In companies with fewer than three hundred employees, the employer may defer the employee’s leave or the start of the period of part-time work if exercising this right would result in the number of hours of leave requested being excessive in relation to the total number of hours worked in the year.
However, the number of hours of leave to which an employee is entitled may, at the employee’s request, be carried over from one year to the next, provided that the total number of hours carried over does not exceed four years.
