So I have been working a very casual job and have been for almost two years. My employer and I have sign a contract explaining my wage and when she will pay it (which is once every month). Anyways, I notice there appears to be a missing payment of 9 dollars in my paycheck this month. My employer has been on par with all my previous paychecks.
I have asked a friend and my co-worker and I have two rational sounding courses of action of what to do.
My friend said I should just let it go and brush it off because if she has been paying me 100% correctly before, then you can give your employer the benefit of the doubt and only tell my employer if this occurs again the next month.
My co-worker says I should tell my employer because I earned that 9 dollars. (She is very vocal about worker rights so I understand her side on this).
What should I do? I am also supportive on worker rights but a one-time mistake over a small amount just seems trivial.
