Work out the notice period when a Belgian employer dismisses you in 2026, with the new 52-week cap, your last working day and the severance pay in lieu.
Leave empty to use monthly salary × 13.92 (12 months, 13th month and double holiday pay)
Notice starts on the Monday after the week in which it is given. Instead of working the notice the employer may pay the severance in lieu; part of the notice can be used for outplacement. Some sectors and contracts before 2014 follow other rules.
What it does
Since 2014 blue- and white-collar workers in Belgium have the same notice periods, set in weeks by seniority: 1 week in the first 3 months, 6 weeks after 6 months, 12 weeks after 2 years, 18 after 5 years and 3 more weeks per year up to 60 weeks at 19 years, then 62 weeks at 20 years and 1 more each year. For contracts starting from 1 June 2026 the notice is capped at 52 weeks, and from 1 August 2026 it is 1 week during the first 6 months. The severance in lieu is the number of weeks × annual pay ÷ 52.
How to use it
