Am I being micromanaged??

I am a LPCA working full time. Have been working at this center for 3 months now . They are driving me crazy . At first my boss made a comment about me having my door closed ( I need the door closed to do notes in silence).

Now on New Year’s Eve I left at 4pm ( the time the center closes). On my schedule I was supposed to leave at 4:30 to clean up the neurofeedback side of therapy.

At 4pm I finished all my notes and I asked the neurofeedback side if they needed help with cleaning up and they told me no I’m all set and everything was done.

Today my boss told me to tell either boss whenever you’re leaving early. Am i crazy or is this micromanaging ? Why do I have to tell them I’m leaving if I completed all that I’m supposed to be doing???
