Periods of notice and unpaid leave?

If you are paid monthly then you have to give 4 weeks notice and if your paid weekly its 1 weeks notice as for the 2 days unpaid each month is something I've never heard of before I'd check wage slips to see if you have been paid for the hours you have worked or have they taken 2 days pay from you? After you 6mths trial period is up you should be entitled to paid holidays from April to April but I'd check with your boss first and if you are entitled to holidays and you leave before taking them then you are entitled to payment for them in your last pay packet
