The calculation of lomaraha depends on the employee’s salary, collective agreement, and the duration of employment. In general, the formula is:

Lomaraha = 50% × (Holiday Pay)

For example, if an employee’s monthly salary is €3,000 and they receive 24 days of paid vacation, their holiday pay is proportional to those days. The lomaraha would then be half of that holiday pay.

Some collective agreements also specify that lomaraha is paid only if the employee takes their holidays as agreed, while others allow for payment even if the employee continues to work during the holiday period.
