are they taking the piss with my tax

[Wessex]

I always calculate deductions as about a quarter of the gross amount and would expect 8 or 9 pounds to be deducted for every 40 pounds earned as a postie.This is a very rough guide to make a quick mental calculation.My normal gross is around 400 a week and I get just over 300 after deductions so my estimate works rather well.

wessex ,how many hours do you work to take home £300 is that full time or with an average ot rate on top

I take home over 300 a week after deductions, pension and cwu subs and small donation, this is ft hours .

I take home a bit less but I buy extra holidays so it probably works out about the same.

I get a weighting allowance in addition to the standard rm wages
