Substitute Days

In accordance with Belgian law, if a public holiday falls on a non-working day (i.e. Saturday or Sunday), it must be replaced by a ‘replacement’ or ‘substitute’ day which falls on a normal working day (Monday to Friday). 

As many businesses in Belgium close on public holidays, most employees are not able to work on these days. However, the employer is obligated to pay employees their normal salary for that holiday, including any bonuses or benefits they would have received if they had worked that day. 

In 2023, two public holidays will fall on a non-working day, New Year’s Day (Sunday 1st January) and Armistice Day (Saturday 11th November). For this reason, Belgian employees are entitled to two substitute days.

Officially, the specific dates of these substitute days are decided by the Joint Industrial Committee responsible for each sector (companies can confirm which joint committee is responsible for their sector by contacting the Belgian Labour Inspectorate). This doesn’t often happen in practice, so in most cases the decision falls to each individual company.

Companies in Belgium can make that decision in one of the following four ways:

  1. Through a Works Council (an external body which represents the collective interest of employees)
  2. Through an agreement between the union representatives and the employer
  3. Through agreement between all company employees and the employer
  4. If no agreement can be reached for the whole company, individual agreements may be created between the employer and each individual employee

If a company cannot decide on substitute days using one of the methods stated above, the replacement day will automatically fall on the next working day following the public holiday (normally a Monday).

Compensatory Rest

In the case that employees are required to work on a public holiday or substitute day, they are required to a period of compensatory rest. This period of rest is equal to one full day if they have worked more than four hours, or half a day if they have worked less than four hours. 

This compensatory rest must fall on a typical working day for the employee and be granted no more than six weeks following the public holiday or replacement day.
