Overtime work must be the result of a management decision. Only employees who are prepared to work overtime should primarily be requested to do this.
You should not be required to work overtime if you are unable and have valid reasons.
The employer has no right to require you to work overtime if you are on partial sick leave, on partial leave by virtue of legislation or taking care of a sick child. An employee who is partially retired cannot be required to work overtime for more than 25 hours per calendar year.
If the employer judges that there are special needs, an employee can be ordered to work a maximum of 48 hours overtime during a period of four weeks or 50 hours during a calendar month but of no more than 150 hours per calendar year. Overtime compensated by leave is not included in the total amount of overtime per year referred to in this paragraph and the paragraph above.
