Pumping at work

Hello all! I will be a ftm in January and will need to go back to work after my 12 weeks. I’m a high school teacher, and we have 85 minute long classes but are on an even/odd schedule. So one day I’ll have first period prep, and go he following day I have prep after lunch. I only get a 30 minute lunch, assuming I don’t have two meetings during that time.

I’m curious if pumping at work will even be an option, and how you teacher moms have made it work.

Thanks in advance!
