How about I put extra hours on my time sheet at my job because I've been told every week for the past eight months that my raise would be on my next check.
You can't be serious. Why did you add the extra hours? Was it to help with a problem? Did you think it would make you liked?
People there hate me
It's understandable to want to get what you were promised, but its wrong to lie and falsify your timesheets at work. You could end up getting accused of stealing and be fired.
I don't need to work in that place.
But then why don't you just look for another job? It would be easier than doing wrong by adding those extra hours. It is actually something that they will tell your next employer too if you are fired and need their references.
