-- Low pay. Only pay raises without promotion come with annual reviews, up to 3% based on performance. These don't happen every year though. In my 5 years, I only had two "annual" reviews.
-- As in any job, a lot depends on management. If your center director is reasonable, you may not bear as much of the brunt of how crazy the corporate leadership really is. If not, things can turn very abusive very fast.
-- Benefits are pretty abysmal. I always found the Obamacare marketplace had better options than what was offered to full-time employees through the company.
-- Online instruction is difficult. Kids are often plopped in front of computers, and it is difficult to keep them on task without them physically in front of you. The instructor and/or consultant inevitably get blamed.
-- This is actually a pretty common narrative. Most employees are hired right out of college, on summer break, etc. and given a great deal of responsibilty without any experience or guidance. Ostensibly there is supposed to be mentoring, but for me this was about 3 hours in my first week. Then staffing issues lead to battlefield promotions. Freshly hired 21-year-olds being asked to write lesson plans and update parents, feigning expertise. This would be one thing if it were just some summer camp, but parents pay tens of thousands of dollars for their kids to come here for remedial instruction, and the company will just throw three raccoons in a trench coat into center leadership positions and then swindle these parents into thinking only the most highly trained expert instructors are looking after their kids' instruction.
