You obviously don't know the statutory rights regarding employment contracts.. let me cut and paste direct from the .gov site..
" Your employment contract
An employment contract is an agreement between you and your employer. If you have been employed for over one month, by law you must be given a written statement of your terms and conditions. You should receive this within two months of starting work, even if you are going to work for them for less than two months. Generally, your employer needs your permission to change the terms and conditions of your contract. You should always check your employment contract to see what you are entitled to. If your employment contract says you should get something more than the statutory minimum (eg higher pay than the National Minimum Wage), your employer must give this to you."
That's it nothing else as far as I can see.
