Vantaggi
If you're passionate about education, it's wonderful going to work every day with similarly minded people. The work-life balance is still pretty great, even if it's gotten worse over the past few years (less flexible hours, less working from home, etc). Your coworkers are great people, many of the mid-managers genuinely care and want to help and look out for their employees.
Svantaggi
As other people have said, the learning curve is STEEP. Plus, with all the reorgs and moves and lay-offs, we're severely understaffed and the staff we DO have is all new, unexperienced and overworked. However, the biggest problem by far is salary. Speaking as someone in a junior position in one of the most expensive cities in America, the salary is just not enough to live off of, especially considering how understaffed we are and how much our workload/responsibilities has expanded over the past two years. Once the hiring freeze is lifted, if you manage to find people who are willing to work for such a paltry sum they're most likely going to stay long enough to put it on their resumes, then leave for a company that's willing to pay them a livable wage. In the meantime, you're losing multiple people a week to similar companies who pay more, and out of the remaining people left, nearly everyone is job hunting.
