ILC, Why did you email him and not go into his office to talk to him? Are you afraid of him? Are you an adult or are you a child? You either have to stand up for yourself or take what you get. Either walk in to his office and speak up, or stay home it is your choice. If you choose to go to work when this is NOT settled then YOU are choosing to accept how they are treating you. If YOU want to get paid as an adult then you either walk into his office or call him on the phone and let him know how you feel and tell him where he can find you. You can let him know that you are highly insulted if he called you back to work just to take advantage of you and pay you what he paid you as a kid. If he called you back because he trusted you with the youngest bunk and needed you for the job, then you expect to get paid like any other trusted counselor or teacher.
It is your choice whether to continue working there no matter what or to stand up for yourself and ONLY work there if they treat you equally as someone else with your experience. Only you can decided how you wish to be respected and treated. Allowing someone to treat you poorly only to complain about it is wrong and YOU are the one responsible for allowing that a to happen.
