Night Work
Night work (from 11:00 p.m. to 6:00 a.m.) and Sunday work (from 11:00 p.m. on Saturday to 11:00 p.m. on Sunday) are generally prohibited.
Night work may be authorized if certain conditions are met. Permanent or regularly recurring night work is authorized by SECO, while temporary night work for up to 10 nights per calendar year is authorized by the cantonal authority. You can find the form for applying for a night work permit from the Canton of Schwyz at the following link.
In the case of temporary night work (fewer than 25 nights per calendar year), the employer must pay a wage supplement of at least 25 percent. In the case of permanent or regularly recurring night work, the employee is entitled to compensation equal to 10% of the time during which he or she performed night work. The compensatory time off must be granted within one year (see Art. 17b ArG; Art. 31 ArGV1). Employees who are paid by the hour also receive the 10% time allowance for regular night work in the form of paid time off. Art. 22 ArG prohibits the compensation of compensatory time off with monetary payments (link).
Special provisions apply to certain categories of employees and businesses, allowing night work without prior authorization (see Ordinance 2 to the Labor Act).
In general, an employee may not be required to work on Sundays or at night without his or her express consent.
Night work may be regulated on a case-by-case basis in a collective bargaining agreement.
