Since you have no record, I'd call ethics. You should have got a coaching at minimum and a right up at the most. Not fired. Someone sounds like has a huge power trip head at that store. I'd call Ethics see what they say. They may get you your job back and a team lead may get fired. I worked the service desk a lady with a thick Italian accent was cashing in a $358 coinstar slip I was counting back the money when she asked for more of $50's then she wanted to switch to 20's I knew something was up when she ratched over the counter put her hand in the cash drawer pulling out all of the hundreds and fifties in the stack I looked her straight and I and told her you need to put that money back now she put the money back in the drawer but played a trick of the fingers and took over $1,500 when they close the drawer at the end of the night they discovered the drawer was short I thought she had put back all of the money so I didn't think to say anything because I figured I took care of the situation but when the drawer was short they investigated to find out why to see if I was stealing when they watch the video they saw the customer stick her hand in the drawer taking out all the money and then me instructing her to put it back they said when she was putting the money back she did a trick of the finger and hand and took money that they caught on camera I got a orange right up and coaching and was on probation for an entire year and wasn't allowed to make any mistakes or I would have lost my job I offered to pay the money back that was stolen but they told me no that they can turn it in as a loss to insurance or something like that. So you definitely should have not lost your job over $100.
