My understanding in most locales: Terminating an employee without cause is acceptable for at will employment, but it means you will be paying them unemployment

My understanding in most locales: Terminating an employee without cause is acceptable for at will employment, but it means you will be paying them unemployment. Firing is terminating an employee with just cause and means you don't have to pay unemployment. If this guys is letting people go because they don't fit into his super-culture, that is the former and not the latter.
