My last day in my previous job was 2 May, so I was expecting just 2 days' pay for the month of May.

However, I checked my online statement today and I've been paid for the whole month of May (as if I still worked there).

I was just wondering what could happen next (obviously hoping they just write it off or don't realise!) and what rights I have and the employer has about recovering the over payment.

(take it as read I'm not going to say anything to them!)
