OK, I have heard some weird news from one company.

They gave their staffs 3 months notice but still cannot hire somebody to do.

Then from their Exit Audit checklist, suddenly bosses can ask them to do something which is not required now but want it done so that the new person comes in, don't need to rush.

I wonder right, if the person really cannot finish the ad hoc items on time, does the company have a right to keep the staff and not allow him/her to leave?

Thanks for the reply guys. So meaning, if the employer decided to hold the leaving staff's salary until the leaving staff submits all the work, the leaving staff can do legal method?
