I'll post my pay slip if you want. A typical shift for me last week:
Out of bed 0415 to be out the house for 0500. Drive 35 miles to Glasgow to start shift at 0600 (petrol cost approx £5).
Class 1 (artic) shift, drive to Aberdeen and back. Finish shift at 1545. Lose 45 minutes pay for unpaid break, despite it being a legal requirement. Drive 35 miles home, another £5 in petrol.
Pay = 9 hours at £8.50 per hour (quite a generous company, usually it's 8.00, or 7.00 if non artic, i.e. tipper!).
Gross pay = 76.50
20% tax = 15.30 (basic rate as second income).
NI = 4.20 approx
Net pay = £57
Petrol = £10
So my efforts for the day made me £47 better off, and I worked a 9hr 45min shift for that.
