If you have enough stamps, and the reduction in hours is because your employer is reducing your hours rather than you doing it and you are looking for and available for work on those days, then you will be entitled to jobseekers' benefit. The amount you'd get if reduced to 2 days is about €117.60 and if you work three days, it'd be €78.40.

In any case, if your total salary for the year falls below €26,000, you will be entitled to reclaim any health levy you have paid so far this year. This can be done after the year end using form prsiref1 (available on www.welfare.ie).
