Wait. Is it your job, to follow people around who might shoplift?
Or is it your job to fold clothes, put them on display, and ring out customers?
Troy and Shikago are right dude.
Not your job description.
Edit: my job is to assist therapeutic strategies for the kids where I am at. Not to make diagnosis, or recommend medicine changes, or say "(therapist), (client) is not making any strides for the better, this s--- needs to change".
He didn't follow them around or call the cops. From what I see, he noticed something that could potentially be a shoplifter, and notified management of it, and in his own words, went back to his register. The reason there are managers in the first place is to properly handle situations like this - and if how this was posted is how it went down, I'd have a lot more fault for the manager calling the police needlessly than for the employee notifying management of a potential concern.
So, trying on clothes is potentially shoplifting now? I mean, I can see the logic, I know what size I am and don't try things on... but that poses a serious problem for a lot of people.
Sure the manager could of handled differently... but if the guy is wearing the shirt, and in the store for a half hour... odds are near 0% he's a shoplifter. In a half hour, PLENTY of camera's have seen you, so its not like you can be an in and out guy, which is the point of shoplifting.
If I were the customer, I would file a complaint too, course, as a customer, the complaint would have been against the store/manager, and not some retail jockey employee. I would not even notice the retail employee unless they were following me, or made a comment that struck a chord on me where I would check their name tag and remember it.
I think there is more to the story than we are being told. But yes, I feel his complaint, valid. But as someone else said. Complaints against you, usually mean your doing your job right.
