We are an industrial company in Aarau with around 340 employees. At our company, employees can currently buy up to ten additional days of holiday per year, for full-time employment; individually or in a block. The purchase price is deducted from the salary in the month of the order, or in the following month if the order is placed after the 20th. The purchased days are taken within one year, in one block or individually, without approval by HR or line managers. Anyone who needs more can apply for unpaid leave; this requires the approval of the line manager and of HR, and we hand out an information sheet on accident insurance and the pension fund. We are considering extending the holiday purchase to fifteen or twenty days, so that someone with purchased days can be away for up to a month. An employee with a monthly salary of 8'000 francs wants to buy twenty days at once and take them in one block in February. We are unclear whether, for insurance purposes, the purchased days count like unpaid leave.
Before the analysis runs, LEXchat asks about what the facts leave out. Only what the text already stated was answered.
Should the extension of the holiday purchase to fifteen or twenty days be examined specifically?

Is the approval of line managers and HR required for the purchase of twenty holiday days?

The "holiday purchase" is an agreement on additional holidays beyond the statutory minimum in exchange for a waiver of salary; under Art. 19 para. 1 OR it is permissible as long as the statutory minimum holiday entitlement of four weeks (Art. 329a para. 1 OR) remains untouched and the full holiday pay under Art. 329d para. 1 OR is paid for it (mandatory under Art. 362 para. 1 OR) — the extension to 15 or 20 days is therefore possible in principle, but as the quota grows it comes closer to a disguised shifting of the holiday pay risk onto the employee, which the Federal Supreme Court rejected in BGE 118 II 136. For insurance law purposes, what matters is not the label but the actual salary entitlement (Art. 18 para. 1 OR): under Art. 3 para. 2 UVG, accident insurance ends only on the 31st day after the entitlement to at least half the salary ceases, whereas the occupational pension relationship under Art. 10 para. 2 BVG continues without interruption as long as the employment relationship continues and the annual salary exceeds CHF 22'680 (Art. 2 para. 1, Art. 7 para. 1 BVG) — the two branches are thus treated differently. Prognosis: under the current design (deduction in the month of the order or the following month, unreduced salary payment in the month the days are taken) no extended cover period runs; action is needed above all regarding the staggering of deductions, the coordinated salary and the approval requirement for large withdrawals.
1. Legal nature of the holiday purchase and permissibility of the extension (work assignment 1)
The holiday purchase is not a holiday arrangement in the technical sense, but a two-part agreement: a waiver of part of the salary entitlement (Art. 322 para. 1 OR) in exchange for release from the obligation to work (Art. 319 para. 1 OR) for a certain number of days; whether in the individual case there is a reduction of the agreed salary or a set-off against a purchase price claim is not decided by the label alone, but must be qualified on the basis of the agreement, the payslip under Art. 323b para. 1 OR and the time of payment. Under Art. 18 para. 1 OR, what matters is the true and common intention of the parties, not the designation as "holidays". Economically, it is a selective, consensual suspension of the principal obligations — i.e. the same structure as unpaid leave, the only difference being that the salary deduction is brought forward in time.
The agreement is permissible under Art. 19 para. 1 OR insofar as it does not conflict with mandatory law. Limits:
The standard of Art. 329d para. 1 OR is strictly amount-based: what is owed is "the entire salary attributable to them" — i.e. for each of the four or five statutory holiday weeks, the salary the employee would have received had he worked. In concrete terms, this means for the pricing and payroll mechanics: the purchase price per purchased day may not exceed the share of salary attributable to one working day, the deduction must be allocated exclusively to the purchased days and shown as such on the payslip (Art. 323b para. 1 OR), and in the months in which ordinary holidays are taken no purchase price deduction may reduce the holiday pay — otherwise the employee bears a loss on the mandatory holiday pay contrary to Art. 329d para. 1 OR.
Interim result: The extension to 15 or 20 days is permissible if the regulations lay down (i) the subordination of the purchased holidays to the ordinary holidays, (ii) the equivalence in amount between the purchase price and the salary forgone, and (iii) that the entitlement under Art. 329a para. 1 OR remains unaffected.
2. The salary deduction — reduction of gross salary or set-off? (the doctrinal pivot)
The entire insurance law assessment depends on how the deduction is structured:
Variant A — reduction of gross salary: The agreed salary (Art. 322 para. 1 OR) is reduced for the month concerned. Consequence: the relevant salary under Art. 5 para. 2 AHVG decreases, and with it the annual salary under Art. 7 para. 2 BVG and the insured earnings under Art. 22 para. 2 UVV.
For occupational pensions, however, this consequence is not inevitable: under Art. 3 para. 1 let. b BVV 2, the pension fund may determine the coordinated annual salary in advance on the basis of the last known annual salary, and under Art. 3 para. 1 let. a BVV 2 it may disregard salary components that arise only occasionally. Whether the purchase price deduction reduces the coordinated salary at all therefore depends primarily on the regulations of the pension fund; if the fund relies under Art. 3 para. 2 BVV 2 on the salary paid for a given payment period, the deduction has an immediate effect, but the employee remains subject to mandatory insurance even if his salary temporarily falls below the minimum amount.
Variant B — set-off of a purchase price claim against the unreduced salary: The gross salary remains unchanged; the AHV, BVG and UVG bases remain in full. In return, Art. 323b para. 2 OR applies: set-off only to the extent that the salary claim is attachable (Art. 93 para. 1 SchKG); under Art. 361 para. 1 OR the provision is mandatory for both parties, and the employee's consent does not cure an excess. Whether a direct charge agreed in advance is "set-off" within the meaning of Art. 120 para. 1 OR and Art. 323b para. 2 OR at all, or is regarded as a mere modality of salary determination, is an open question of judgement — I expressly flag it as such and advise a conservative treatment.
Concrete calculation for the case at hand (monthly salary CHF 8'000, 20 days):
| Item | Amount |
|---|---|
| Annual salary (12 × 8'000) | CHF 96'000 |
| Daily rate 96'000 ÷ 260 working days | CHF 369.25 |
| Purchase price 20 days | CHF 7'385 (alternative rate 8'000 ÷ 21.75 × 20 = CHF 7'356) |
| Annual salary after deduction | CHF 88'615 |
| Coordinated salary so far (capped at 90'720 − 26'460, Art. 8 para. 1 BVG) | CHF 64'260 |
| Coordinated salary after deduction (88'615 − 26'460), provided the regulations rely on the effective salary (Art. 3 BVV 2) | CHF 62'155 |
| Reduction of the insured salary | CHF 2'105 (approx. 3.3%) |
The purchase price practically corresponds to a full monthly salary. A deduction in a single month means that in that month the entitlement to at least half the salary (CHF 4'000) is no longer met — with the consequences set out under no. 3. If the deduction is staggered over three months (approx. CHF 2'462 each), CHF 5'538 remains each month, i.e. clearly more than half.
3. Question 1: Accident insurance — do extended cover periods run?
Under Art. 1a para. 1 let. a UVG in conjunction with Art. 1 UVV, mandatory accident insurance requires that insured employee status exists at the time of the accident. Under Art. 3 para. 2 UVG it ends on the 31st day after the day on which the entitlement to at least half the salary ceases. Under Art. 7 para. 1 let. a UVV, salary means the salary relevant for AHV purposes.
Under Art. 1 UVV, an employee within the meaning of Art. 1a para. 1 let. a UVG is anyone who carries on a dependent gainful activity within the meaning of the AHV legislation; the link is thus to the qualification under AHV law and not to the amount of salary paid in an individual month. Since in the case of the holiday purchase the employment relationship continues without interruption and the activity remains dependent under AHV law, insured status is preserved; the only decisive factor is the salary entitlement under Art. 3 para. 2 UVG in conjunction with Art. 7 para. 1 let. a UVV.
BGer 8C_587/2024 holds that during unpaid leave the essential obligations under the employment relationship are suspended and that there is no cover if a continuing salary entitlement is not proven; BGer 8C_413/2019 confirms the same link to Art. 3 para. 2 UVG for unpaid leave. Accordingly, what matters is not the label "holidays" or "unpaid leave", but the salary entitlement in the period in question.
For your model, this means:
4. Question 2, first part: Do the UVG and the BVG treat the days differently?
Yes, and structurally so. The BVG is not linked to the salary entitlement in an individual month, but to the existence of the employment relationship and to annual salary thresholds:
Coverage here follows exclusively from Art. 2 para. 1 BVG (employee status); the subjection of self-employed persons under Art. 3 BVG requires an application by the professional association and plays no role for your employees. The relevant figure therefore remains the annual salary under Art. 7 para. 2 BVG, and in the case of employment for less than a year the salary converted to a full year (Art. 2 para. 2 BVG) — relevant for employees joining in the year of the holiday purchase.
Consequence: occupational pension cover continues without interruption; there is no gap in cover and no extended cover situation. The one-month continued cover for death and disability under Art. 10 para. 3 BVG presupposes the termination of the pension relationship and is not relevant here.
What may be affected, however, is the amount of benefits: if the annual salary relevant for pension purposes decreases, the coordinated salary under Art. 8 para. 1 BVG decreases — in the case at hand by approx. CHF 2'105; whether this happens is determined by Art. 3 BVV 2 and the pension fund regulations, which is why the figure must be verified with the pension fund before any communication to employees. The protective provision of Art. 8 para. 3 BVG does not apply: it covers only temporary salary reductions due to illness, accident, unemployment, parenthood, adoption "or for similar reasons" and links the duration to the obligation to continue paying salary under Art. 324a OR. The holiday purchase is not a hindrance through no fault of the employee, but a voluntary suspension; there is precisely no entitlement to continued salary payment under Art. 324a para. 1 OR for it. Whether "similar reasons" should be understood more broadly is an open question of interpretation — in light of the meaning and purpose of the provision, it is to be answered in the negative.
There is scope for design in the pension fund regulations: under Art. 49 para. 1 BVG, pension funds are free to design their benefits and their financing and, under Art. 50 para. 1 let. a and c BVG, issue provisions on benefits as well as on administration and financing. A regulatory clause under which the previous coordinated salary is maintained in the event of a holiday purchase and unpaid leave is readily possible; parity of contributions under Art. 331 para. 3 OR and Art. 66 para. 1 BVG must be observed (the exception in Art. 33a para. 3 BVG concerns only continued insurance after the age of 58 and does not fit here).
The freedom of design is not unlimited: under Art. 1 para. 1 and 2 BVV 2, the pension plan must remain appropriate, i.e. the regulatory benefits may not exceed 70% of the last insurable salary subject to AHV contributions before retirement, or the retirement credits may not exceed 25% of the insurable salaries subject to AHV contributions (Art. 1 para. 2 let. a and b BVV 2). A clause that maintains the previous coordinated salary despite a holiday purchase must be measured against this limit — at the order of magnitude in question here of approx. 3% of the annual salary, it is unproblematic.
5. Question 2, second part: Reporting obligations
Neither the UVG nor the BVG provides for a reporting obligation for the "holiday purchase" as such. What must be reported are the salary bases:
In passing, but of practical relevance: according to BGE 137 V 121, there is no legal basis for family allowances during unpaid leave that is not specifically justified. As long as salary is paid in the month the days are taken, this problem does not arise with the holiday purchase; it very much does, however, in a model with a salary reduction in the month the days are taken. The contribution period in unemployment insurance (Art. 13 para. 1 AVIG) remains unaffected, as the employment relationship subject to contributions continues.
6. Question 3 and work assignment 3: Approval requirement and further points at 20 days
Approval: Under Art. 329c para. 2 OR, the employer determines the timing of the holidays and takes the employee's wishes into account insofar as this is compatible with the interests of the business. Under Art. 362 para. 1 OR, the provision is mandatory in favour of the employee; a voluntary waiver by the employer of its right to determine the timing (withdrawal without approval) is permissible as a more favourable arrangement, but is not required by law. Introducing an approval requirement for large withdrawals is readily permissible and is based on Art. 321d para. 1 OR; it is strongly recommended for a withdrawal of 20 consecutive days, as the interests of the business are considerably affected. Note: for commitments already in force, the subsequent introduction of an approval requirement is an amendment of the contract that requires consent or would have to be enforced by means of a notice of termination with an offer of modified terms under Art. 335 para. 1 OR; the introduction of the extended quota itself is a more favourable arrangement and can be tacitly accepted under Art. 6 OR (freedom of form: Art. 320 para. 1 OR, Art. 11 para. 1 OR). Public-sector staff law (for instance Art. 41 para. 2 PVBger with the express reservation of undisturbed operations, or Art. 36 para. 1 PersR of the Aargauische Gebäudeversicherung with the requirement of approval by the executive board from four weeks) does not apply to your private-law employment relationship, but illustrates widespread regulatory practice.
Reduction of holidays: Art. 329b para. 1 OR permits a reduction of one twelfth per full month only in the case of a hindrance through the employee's fault; para. 2 prohibits a reduction in the case of a hindrance through no fault of the employee of up to one month. The holiday purchase and unpaid leave are not a "hindrance" within the meaning of this provision, but a consensual suspension. According to BGer 4A_319/2019, the reduction in the case of incapacity to work through no fault of the employee is governed by Art. 329b OR and not by a mere pro rata calculation based on Art. 329a para. 3 OR; whether, conversely, a pro rata reduction of the ordinary holiday entitlement under Art. 329a para. 3 OR is permissible in the case of a consensual suspension is an open question of judgement. The public-law rules (Art. 67a para. 1 let. b BPV: 22 working days; Art. 41 para. 4 let. b PVBger and Art. 29 para. 1 let. b AZGV: 30 days of unpaid leave each; Art. 36 para. 1bis PersR AGV: proportionate reduction) show that this question is regularly governed by positive law — you should answer it expressly in the regulations. For the purchased days, the following applies mandatorily: they do not give rise to their own holiday entitlement ("no holidays on holidays") and may not reduce the ordinary entitlement under Art. 329a para. 1 OR.
Further points to regulate:
Limitation: claims arising from the employment relationship become time-barred under Art. 128 no. 3 OR after five years, to which Art. 341 para. 2 OR refers; records of purchase prices and holiday pay must accordingly be kept for at least five years. The determination of salary for pension purposes is governed by Art. 3 BVV 2 in conjunction with the regulations of the pension fund.
This is advice on structuring; the risk does not materialise in pending proceedings but in two scenarios.
Scenario A — employee action for holiday pay. An employee claims that the purchase agreement is void under Art. 362 para. 2 OR and that holiday pay must be paid retroactively under Art. 329d para. 1 OR. Key argument for the employee: BGE 118 II 136, according to which agreements that burden the employee with the risk of salary losses in connection with holidays violate Art. 329d OR. Key argument for the employer: the purchased days lie outside the mandatory minimum of Art. 329a para. 1 OR; in the area beyond the statutory minimum, Art. 19 para. 1 OR applies, and the agreement is made at the request and in the interest of the employee. With proper documentation, I consider the employer's argument to be clearly stronger; the risk does, however, increase measurably if the order of withdrawal is not regulated or the purchase price exceeds the salary forgone. Burden of proof: the employer must prove that the holidays owed were actually granted and paid (as held in cantonal practice in Higher Court C-24719-2013 and Higher Court C-22737-2015); an estimate under Art. 42 para. 2 OR comes into consideration only where proof is objectively impossible. Practical consequence: separate time balances for ordinary and purchased days, kept for the entire limitation period.
Scenario B — insured event during a large withdrawal. This is where the actual liability risk lies: if the UVG insurer denies cover on the basis of Art. 3 para. 2 UVG and the line of BGer 8C_587/2024 and BGer 8C_413/2019, the employee will hold the employer liable for breach of the duty to inform (Art. 328 para. 1 OR). In the case of 20 consecutive days with continued salary, cover exists according to the view taken here; the residual risk lies in the question of qualification and in the calculation of the daily allowance under Art. 22 para. 3 UVV. For non-occupational accidents, this risk can largely be absorbed by extended cover by agreement under Art. 3 para. 3 UVG in conjunction with Art. 8 UVV — weighing cost against risk, this is clearly the preferable solution; for occupational accidents it remains ineffective, which is why it must additionally be ensured that a salary entitlement of at least half continues in the month the days are taken.
Costs. Employment law disputes with an amount in dispute of up to CHF 30'000 are privileged before the Federal Supreme Court with a court fee of CHF 200–1'000 (Art. 65 para. 4 let. c BGG); the allocation of costs follows Art. 66 para. 1 and Art. 68 para. 1 and 2 BGG. With 340 employees, however, the actual cost risk lies not in the individual case but in the multiplier effect of a void standard clause.
7a. Clarify the definition of salary for pension purposes: before any calculation, ask the pension fund in writing whether it determines the coordinated salary in advance under Art. 3 para. 1 let. b BVV 2 on the basis of the last known annual salary or relies under Art. 3 para. 2 BVV 2 on the salary paid per payment period; this determines whether the purchase price deduction affects the insured salary at all. Result: file note with the pension fund's answer and the resulting figures, supplemented by confirmation that maintaining the previous coordinated salary complies with the appropriateness limits under Art. 1 para. 2 BVV 2.

| Art. 3 UVG | Insurance begins with the employment relationship or the first salary entitlement (para. 1) and ends on the 31st day after the day on which the entitlement to at least half the salary ceases (para. 2); extension by agreement for up to six months (para. 3). | Central connecting provision for questions 1 and 2: decides on the extended cover period and the need for action in the case of large withdrawals. |
| Art. 10 BVG | Mandatory insurance begins when the employment relationship commences and ends, among other things, upon its termination or when the salary falls below the minimum salary (para. 2 let. b and c); extended cover for death and disability for one month (para. 3). | Demonstrates the BVG's different connecting factor compared with the UVG: no interruption of the pension relationship in the case of a holiday purchase. |
| Art. 8 BVG | The annual salary from CHF 26'460 to CHF 90'720 is insured (para. 1); in the event of a temporary drop in salary due to illness, accident, unemployment, parenthood, adoption or similar reasons, the previous coordinated salary is maintained (para. 3). | Quantifies the loss of benefits resulting from the holiday purchase (here approx. CHF 2'105) and shows that the protective provision of para. 3 precisely does not apply. |
| Art. 329a OR | Entitlement to at least four weeks of holidays per year of service, five weeks until the age of 20 is reached (para. 1); pro rata entitlement in an incomplete year of service (para. 3). | Mandatory lower limit (Art. 362 para. 1 OR) that the holiday purchase may not touch — core of the permissibility assessment. |
| Art. 329d OR | Full holiday pay during holidays (para. 1); prohibition of compensation during the employment relationship (para. 2). | Para. 1 is mandatory in favour of employees (Art. 362 para. 1 OR), para. 2 mandatory for both parties (Art. 361 para. 1 OR); benchmark for allegations of circumvention under BGE 118 II 136. |
| Art. 323b OR | Written payslip (para. 1); set-off of counterclaims only to the attachable extent (para. 2); nullity of agreements on the use of salary in the employer's interest (para. 3). | Limits structuring the purchase price deduction as a set-off; under Art. 361 para. 1 OR para. 2 is mandatory for both parties and cannot be waived by consent. |
| Art. 22 UVV | Maximum amount of insured earnings CHF 148'200/year (para. 1); insured earnings are the salary relevant for AHV purposes (para. 2); for the daily allowance, the last salary received before the accident applies (para. 3). | Explains why a month with a full purchase price deduction can distort the amount of the daily allowance — key argument for staggering the deduction. |
| Art. 3 BVV 2 | In its regulations, the pension fund may deviate from the salary relevant for AHV purposes, disregard occasional salary components, determine the coordinated annual salary in advance on the basis of the last known annual salary (para. 1) or rely on the salary paid per payment period; in the event of a temporary drop below the minimum amount, coverage is maintained (para. 2). | Decides whether and to what extent the purchase price deduction reduces the coordinated salary at all — the calculation is reliable only with the specific regulations. |
| Art. 1 BVV 2 | Appropriateness of the pension plan: benefits of at most 70% of the last insurable salary subject to AHV contributions, or retirement credits of at most 25% of the insurable salaries subject to AHV contributions (para. 2). | Outer limit for maintaining the previous coordinated salary under the regulations in the event of a holiday purchase and unpaid leave. |
| Art. 1 UVV | An employee within the meaning of Art. 1a para. 1 UVG is anyone who carries on a dependent gainful activity within the meaning of the AHV legislation. | Demonstrates that insured status is linked to the qualification under AHV law and not to the amount of salary in an individual month; the holiday purchase does not affect it. |
| Art. 2 BVG | Employees over 17 with an annual salary of more than CHF 22'680 are mandatorily insured (para. 1); in the case of employment for less than one year, the salary converted to a full year applies (para. 2). | Coverage provision for your employees; shows that the purchase price deduction is far from affecting the entry threshold. |
| Art. 3 BVG | Occupational groups of self-employed persons are subject to mandatory insurance only upon application by the professional associations. | Delimits the substantive scope of coverage: for employees, only Art. 2 para. 1 BVG applies, which is why the holiday purchase raises no question as to the type of coverage. |
The legal review stays with you. The structuring groundwork does not.
