Day rate 'After tax'?

Carryfast:
Daily rate, job rate, per mile rate or per hour rate it makes no difference.Its all about the work load and duties expected ‘in a day’.
IE £15 per hour class 2 based on an 8 hour day local multi drop all handball.
Or £10 per hour based on a 12 hour day distance trailer swaps only trunking regardless of how it’s calculated hourly or job rate.
Which would you prefer.

Its not difficult to see why you spectacularly failed at this job is it!

Or you could simply go for option 2 but at your chosen figure of £15 per hour. No idea why you found that so difficult when trying desperately to find a job, actually on second thoughts we all know why you couldn’t achieve it.
