If you will be available for and seeking full time work, and have sufficient Class A PRSI contributions, then you may qualify for Jobseeker's Benefit. JB is paid for a maximum of 12 months. If you are still unemployed at that stage, you can apply for the means-tested Jobseeker's Allowance.
If you pay Class D PRSI contributions (which clerical/admin staff recruited before April 1995 pay), you won't qualify for JB.
Can someone get Job Seekers Benefit if they are in a part time job and need to find a full time job for financial reasons e.g. a person working week on / week off for just 20 hours in the week they work i.e. average 10 hours per week overall?
