If the employer reports the thefts to the police, and the suspicions that the employee committed the thefts, the police will review the evidence to try to determine if they could build a case against the employee. If they find that they have probable cause, they will have a prosecutor review their findings and recommendation and, if the prosecutor agrees, then the employee can be criminally charged for the acts of theft.

Even if the employer does not go to the police, or the police don't find sufficient evidence to support a finding of probable cause that the employee was the thief, the employee can reasonably expect to be fired.
