During the first six months of service, Workers are entitled to 1 day of paid vacation for each month worked. After six months of continuous service, Workers are entitled to a minimum of 20 paid working days of vacation per year. If a Worker worked for the same employer prior and there were 15 days or less between the two periods of employment, they do not have to observe the six-months of reduced vacation. Rather, they are immediately entitled to the minimum of 20 paid working days of vacation per year. Each calendar year, the Worker must use at least 12 days of annual leave in an uninterrupted period. The remainder can be carried over to the following year, but must be used by June 30 of that subsequent year. Accrued but unused leave is only payable at the end of employment if it was the employer's fault that the leave could not be used (e.g. economic, organizational, or technical reasons). It is not payable if the Worker resigned or was terminated due to a breach of work duties. Workers may not elect to receive their annual leave allotment as a payment in lieu of time off.
