Employers can control who else you wish to work for, they hold your P45, they pay into your pension, NI etc.
They have to pay your pension and NI, it is a legal statutory requirement. And what does the fact they hold your P45 have to do with anything?

The problem with a second job is you pay more in tax, than you earn, unless its for cash.
This old â– â– â– â– â– â– â– â– again.
No you don’t. You pay no more in tax than you would if you had one job paying the same amount as both jobs do. What you don’t get is a second chunk of tax free pay because you already have all your personal allowance applied to the first job. But you pay no more tax if you earn £20,000 in your main job and £10,000 in your second job than you would if you had just one job paying £30,000.

I suppose that if going by the rules, then the hours you work are averaged out over a 17 week period, holidays are not included, so by working your holidays, you may not adhere to the regulations,
Holidays are counted as a 48hr working week under the working time directive to stop employers abusing holidays to lower the average.
Jesus don’t you two know owt?
