Economy is doing OK, but is falling back.
However due to brexit, a lot of EU casual / seasonal workers don't bother with uk now, so plenty of farm work / low skilled building work about.
Problem is cost of living in areas with these jobs is high, tax comes in at a far lower level than here and unemployment benefits are dreadful.

Try it for a couple of months, but I suspect it won't be the promised land you thought.
I had sites in Maidenhead outside London, Bricklayers making £1100 per week and rent for a 2 bed flat in town centre was only 900 per month.
Shopping, electricity and other consumables were much cheaper than in Ireland. The UK leaves Ireland in the dust when it comes to opportunities.
