Can I asue a corporation if their employees stole from me while on duty?

Employers are responsible for the acts of their employees if those actions were taken in the course of their duties for the employer.  business.  For example, if a pizza delivery van negligently causes an accident.  I don't think the intentional actions of these employees would fit, but it might be worth a shot.   An employer can also be liable for negligent hiring/retention of an employee if the employer knew or should have known that the empployee was not suitable for the job, and that employee's actions damaged a customer.   For example, if the employees here had had numeorus prior complaints against them for theft and the employer had kept them on anyway, the employer might be deemed responsible for their theft of your valuable.  While this is possible here, at this point you don't seem to have any facts to support this theory.
