I am a professional, but was treated like an intern.
Pros
Nice co-workers. Easy schedule IF you want part-time work. Provided supplies. Reimbursed some driving mileage. Many schools will provide free lunch.
Cons
Poverty wages for a Masters degree level job, no support from management, principals and supervisor spoke behind our backs, my supervisor was not qualified to give feedback to school counselors-she has no concept of what school counselors do. We are told that "the teachers don't like you" and expected to go to work feeling confident. It was also discovered that my supervisor lied to her employees to fit her own agenda. Zero constructive criticism- only put downs. The year before I left I almost went to Corporate to report my supervisor for making comments about my marriage and my husband's income at a meeting.
