Pros
Not many: Minimal behavior problems to deal with, no work to take home, and the false, inflated sense that you're an educator.
Cons
Enough that it merits a list: (1) $17 an hour, zero to no chance of a raise, and no guaranteed/set hours (2) 15 minutes of prep time for every 1.5 hours of class. (3) At one point I was teaching 18 different courses--no joke: History 6-12, English 7-12, Govt., Econ, Music Appreciation, Art, and photography . . . I've never owned a camera. (4) Very little outside resources--there are numerous courses where you have to provide ALL the homework/testing/projects/etc. (5) Upper management pressure to change grades to appease paying parents. (6) Students come and go as the wind blows; you may have a student miss 3 months straight--the job is hourly, you won't be getting paid for the missed classes (7) No staff cohesion. Staff come and go almost as often as students. (8) Students fall into two categories: socially weird or really, really low intelligence; they are not in public school for a reason. (9) Classrooms are small offices occupied by no less than two teachers at a time; can be up to four. (10) You have 45 minutes to review homework and check for mastery, teach an ENTIRE section (for example the French Rev.), and assign the following night's homework. (11) Lunch is a non paid 1/2 hour--eat fast. (12) Several books are designed for college and do not provide answer keys. (13) NO BENEFITS WHAT-SO-EVER. (14) Allegedly, in 2013 Halstrom netted $14 million; the following year they decided color printer ink was too expensive. (15) Most common topic brought up at upper management meetings: very low staff morale. (16) It is impossible to survive on this job alone, a second job/income is necessary. (17) For many parents, Halstrom is not a school but a day care to babysit their obnoxious kids. (18) A large percentage of classes are spent completing students' previous nights incomplete homework. (19) Most popular activity for on-campus students: playing video games on their iPads. Second most popular activity for on-campus students: playing video games on their iPads. Third most popular activity . . . (20) Large gaps of unpaid time are common to have in between classes. (21) Every day is the same as every day before, and will be the same as every day to come.
