This is a hypothetical question. I understand that in ordinary circumstances, when starting a new job, the probation period allows an employer to terminate the employee for any or no reason, provided it's not a form of illegal discrimination.
Does that freedom disappear for the new employer if a person was already working for a previous employer and is head hunted by the new employer? That is, what if a company goes out of its way to make an appealing job offer to someone who is already employed? Would there be cause for legal action if the employee quit his old job to start a new job, then was terminated from the new job without reason shortly after starting the new job?
