Today I resigned. My boss did not take it well. He locked me out of my company email and informed me that he wanted me to work strict office hours during my notice period of 1 week. (9-5 is unheard-of at my company and this is obviously just to inconvenience me). He also sent me a letter to my other email informing me that I'm being fired, and sent it as well to the recruiting company that originally placed me. Because I sent my resignation from my company email, it's difficult to contest the facts as he's presenting them since I don't have access to that email (In retrospect I should have sent it from, or cc'd, my personal email).
The only other co-worker who regularly works in the office is about to start a holiday that will run through my notice period. To be honest, my boss' reaction is such that I don't really feel safe working alone with him in the office for a week.
How can I find out my status and if I am expected to come in next week?
The letter already states that he won't provide any recommendation OR verification of employment (which I'm pretty sure is illegal), but given his reputation and my industry I will not need his recommendation to find other opportunities.
EDIT: I am in the UK, in case that affects anyone's answers.
