Hi Hailey good question.
As a college professor you are going to work long hours. Being a teacher, especially a college professor, is not a 9-5 job. You will be working definitely 50+ hours a week and I know a few who work over 60. You will be spending lots of time at home or in your office creating lesson plans, grading assignments, and meeting to help students. It is a job that requires a significant time commitment so it is something that you definitely should be aware about going in. Being a professor is a lot more than just showing up to class and instructing, there are many out of class roles and responsibilities that you will have to deal with.
I hope this helps and I wish you the best of luck!!
