answer:Welcome to Fluther! May I ask a couple of questions first? What country do you reside in? This will help us help you. Was there any type of written agreement when you took on the new position? If so, do you have a copy of it? What were his grounds for termination? Can you provide his definition of a ‘probational employee”? To me, that means someone who has a defined probation period, and if they do not perform as required during that time, it can be grounds for termination without repercussion, at least in their mind. Are you sure he didn’t mean on a temporary basis, as in a start-up manager? If you live in the US, then yes, you can file a lawsuit. Almost always, in cases of employment disputes, the burden of proof falls on the employer’s shoulders (the defendant) and not on the employee’s (the plaintiff). We can help point you in the right direction, but the best bet is to seek guidance of legal council in your area.
