Re: Holiday pay ?
As far as I know, yes - see :
Annual Leave and leaving employment
It is illegal under the Organisation of Working Time Act, 1997 for an employer to pay an allowance in lieu of the minimum statutory holiday entitlement of an employee unless the employment relationship is terminated. In general, your annual leave is calculated on the basis of hours worked. If you are leaving employment, the calculation of your annual leave is done on the basis of hours worked from the start of the leave year until the date you leave employment. If you were entitled to annual leave on the basis of hours worked and had not taken this leave (or were unable to take this leave) before leaving employment, you are entitled to payment for this untaken annual leave when you finish employment.
