What if I don't care if people steal from my job?
Why don't you care if people steal from your employer?
I hate work and other people
If you have seen your coworkers stealing though, you should report it. It is wrong for employees to steal from the place that employs them.
Then they will hate me.
It's wrong to steal from your place of employment, yet understandable that you don't want to be the one to get a co-worker into serious trouble. It would be best to let your coworkers know that what they are doing is wrong. By speaking up you can prevent them from getting into trouble.
