Today is half day but only for the students. The teachers have to stay for meetings. That’s totally unfair. How can I get out of it?

So when they announced that it was half day which is today I was excited until the assistant staff said teachers and staff are required to work a full day and have a meeting with our teem after the kids leave and still take a lunch break. It’s mandatory. When we all got that you know yesterday, I was bummed. One of the coworkers was right. So Wednesday she said it’s half day Friday which is today. I was excited and happy and so was she. I said we’re getting out early. She said, “Well the STUDENTS, some stay for aftercare, do but I don’t know about us. We have a meeting so we still have to work a full day.”
I told her, “Are you serious? We will have to work a full day?” Then she said, “We’ll that’s how it is, us staff stay behind and work and have meetings. Well, teachers stay longer but still. Hopefully they’ll let us out a little earlier.”
Today is Friday and I’m still happy it is but I gotta get out of staying until 3:30.
We (assistant teachers/behavior coaches) usually clock out at 3:00, but today we have a staff meeting from 1:00-3:30pm.
The teachers have to say until like four or 4:30pm. Man I’m jealous of the students. I’m one of the assistant teachers. I’m 19 going on 20! I have a life too you know!

This is your job. You aren't a kid or a student. A LOT of the time that kids have "half days" its because teachers and staff have trainings or meetings. Of course as an adult and staff member you won't have the same schedule as a literal child. You aren't one.
Unless its a half day due to weather or a holiday break, you will almost never get the same time off as the students. You are paid and held to different expectations because you are an adult being paid to do a job and fulfill your duties.
