I have resigned from my job and gave my employer 30 days notice. The following day she sent me a termination letter stating that it was effective immediately and that I would only be getting paid until that day. Is this allowed? Should I get a severance pay?

Some employment contracts will give the employer the right to waive notice of a resignation. If you do not have an employment contract, or it does not speak to this, then what your employer has done is not allowed, and I suggest you contact an employment lawyer at the number below to discuss your entitlements.
