Illness: 30, 90 or 180 days, notice given during that time is void

Updated on October 24, 2026

After probation, article 336c paragraph 1 letter b of the Code of Obligations stops the employer from giving notice during a full or partial inability to work caused by illness or accident that is not the employee's fault. The period is 30 days in the first year of service, 90 days from the second to the fifth, and 180 days from the sixth. Notice given during that period is void. Notice given earlier, whose period is still running, is suspended. This is not the unfair-dismissal regime of article 336.

Pay and protection are two questions

Article 336c does not say whether wages continue. Continued pay during a no-fault inability follows article 324a CO, an insurance policy or an agreement. Protected days add up within the same year of service.
