I'm convinced that some managers don't know how to be a manager because they get very scared and nervous about confrontation. This story was posted in r/talesfromthejob, and the OP mentions that suddenly his boss cut his paycheck by $3 an hour because they were talking about some coworkers' salaries, and that caused some problems at the store.
Apparently, some people were complaining to the owner that they don't make as much as this person and were asking for a raise. I guess the situation was kind of uncomfortable for this man, who decided to cut this person's salary instead of setting boundaries or giving a fairer explanation as to why they make more than the rest. To keep the peace among the employees, he made that decision, leaving the employee asking what to do.
That's what I mean when I say that some managers don't know how to do their own job…
Firstly, a good manager should be on top of all of their employee's work and know exactly how much they work, how good they are at their job, and as a consequence reflect that on their salary. If the OP is a good employee and knows how to do things, I think it is fair that they make more than the rest. So, the next time people come and ask for a raise, he has some good arguments to defend the other people's wages.
Now, that being said, what's up with the coworker's attitude? I understand that maybe they were disappointed that this person was making more money, but mentioning this to the owner of the store is a lot, because they were snitching on them and revealing they were having a discussion about salary and work conditions… and I'm sure they know this usually doesn't look good when talking to management.
Anyways, this story shows a lack of empathy and ethics across every member of this store, and multiple people need some serious talk about morals and how to defend the current conditions.
