Redundancy
If you are under 55 and get a redundancy payment of more than €50,000 you are disqualified from claiming Jobseeker's Benefit. The table below shows how long you may be disqualified for. The length of the disqualification is at the discretion of the deciding officer (who can take your circumstances into account). Any period of disqualification is subtracted from your total Jobseeker's Benefit entitlement. So if you are disqualified for 3 weeks (which is 18 days payment) your JB claim starts on day 19.
