Re paying it back...
The Govt gave out the €350 "no questions asked" and said they'll sort it out later. That's why you supposed to submit another official unemployment application within 6 or 12 weeks. Then they'll start looking for your accounts, your savings (saving for a new taxi?), if your partner is full-time PAYE and if you're self-employed. How many of us have a few grand (savings) in the bank to pay for insurance, tax bill and/or a new taxi? I reckon SW would say you should spend that first before you claim to be unemployed & start looking for the 'dole' (in it's most general sense).
I'd say a lot of us wouldn't get unemployment assistance in the first place, that's why I think a lot of us will have to pay back the money. My 2cents.
