my wife worked for the second biggest banking group in the country. quit last year but you should see the mess they made of her final wages slip and p45.
* last wage slip they produced showed she

owed over €3000 tax. This was because for some odd reason the tax office incorrectly issued a tax certificate with nil cut of point and nil credits ( doesnt bear to think about) anyway about a week after this incorrect cert they forwarded a corrected one and also a copy to bank. bank acted on first one. also the pay was incorrect as her leaving date wasn't correct. after much written and verbal communication with the payroll of the bank they came up with a corrected (sort of )payslip.
*in the meantime an incorrect p45 was issued by them
* new pay slip was better in that it had now dispersed with the tax deficit but still not 100% correct
* a new p45 shows neither the figures given on the corrected pay slip nor the previous payslip.
* I havn't yet made a tax return for last year and don't know which to go by her last payslip , which at least is closer to the truth or the P45 which is what the bank will have forwarded to the revenue on their p35 listing.
* talking to the payroll section was like talking to the wall
* I was employed on payroll section of my own company for about 10 years and to say that this bank didn't have the basics isnt overstating it. My wife was temorary for the past few years, of her own choice, and this bank didn't even know her holiday entitlements or what dates she worked. I kept a record of dates worked and not worked. Just as well because on one occasion when social welfare sent a form to the bank to confirm dates etc they rang her to ask her did she have a record as they didn't. Unreal.

i should add that she only wanted temporary work with them as she felt permanent work would stop her looking elsewhere for work she though she would enjoy more. And she does.
