My employer somehow found through a thorough background search that I had a grand theft ($300) chrarge that was no action and supposedly expunged.All employees are at-will and they felt it was best to terminate me even though I have done nothing wrong at this job. Can they do that? And how the heck did they find it if the county and fdle have no record of the case??? I can't even start interviewing anywhere else if this case is still floating around somewhere! Please advise.
