I've to think back a bit here but if I remember correctly an employment contract I signed had: 1 weeks notice for the first 3 months, 2 weeks notice for 6 months, 4 weeks notice for over a year. That worked both ways so the employer only had to give 1 week notice in the first 3 months and visa versa. Dunno about your situation or the legality of it all. I'd check with a solicitor as blacknight suggested!
