youd be suprised what they can get away with. i had to take mine to employment tribunal, and the main thing that shocked me was if your claim is under �600 once it gets to the period of notice they have to pay you, and they dont pay, there is nothing you can do!!! �600 is some money for normal people!
also the time periods the eployers get are ridiculous. tbh i dont thnk there is anything your friend can do with not being employed for a year, but go to citizens advice and they will help. or a lot of emploment solicitors give a free consultation
