can your boss give you a written counseling for an issue that you came to them about a week prior?

I am a dept. Supervisor in a retail store. We have a night & morning freight crew. I am the night supervisor. Last week I went to my store mgr addressing an issue of the morning crew not finishing up the merchandise that my team didnt finish. He offered no explanation only that he didnt know he wasnt there & that they were probably working on something but offered no solution. Now a week later he gives me a written verbal counseling regarding the freight not getting done. The counseling states what my job expectations are (which is everything I currently do) and I asked why these expections werent told before and he told me hes "setting my expectations now". So I am wondering if this is retaliation or if theres anything I can do? Thanks!
