I have been an assistant manager at a fast food restaurant for over a year now. I have never been written up or talked too for bad behavior. Then half way through my shift the new manager sat me down and told me I wasn't working out and was let go. I am payed hourly. Can they just let me go like that?

Thank you for your question. Generally speaking, an employee can be let go at any time, for any reason, as long as that reason isn't discriminatory and the employee is provided with with their legal entitlements in terms of termination/severance pay. If your employer let you go without any termination/severance pay, you should contact a lawyer to discuss a potential wrongful dismissal claim.
