Can you be dismissed while in possesion of a doctor's sick note?

Sorry but although it is wrong for you to have been sacked, there is not a lot that you can do, you cannot sue for wrongful dismissal because you have not worked for them for over two years, they have not said that you have been sacked because you have been sick, they have said that it is not working out, you could go to the Citizens Advice Bureau to see what steps you can take though, if any.
