...when I know shes got a longterm cash in hand job that she pays no tax on.
Not just me, half the office knows too. Shes working FT in one job and 15 hours cash in hand at weekends, and has been doing so for 18 months.
Just think its a bit bad form to be boasting about her tax rebate from her FT job when shes raking it in at weekends and paying no tax on this. I know shes working very hard and struggling to make ends meet (shes a single person) but my family was stung with a large tax bill last year and had to cough up loads, whilst shes getting away with it.
