Pros

Salary alligned with the market

Cons

No process. Double standard. Blame culture. Turnover of contingent worker that are used and left asap is the standard. New policy requires to be in the office 4 days per week is removing the only relevant good part of this job. I have never felt more unwelcome in a job.

Pros

pay is ok because of NH income tax thats it

Cons

STAY AWAY!! Unless you enjoy destroying your mental health. The worst managers I have ever dealt with. All they do is belittle you, overwork you, disrespect you, infantilize you, and never appreciate your work. They expect you to be a robot, stay in late for work, do a lot more than your job description but will never appreciate you. Management is completely childish, unprofessional, and deeply toxic. Managers demand that you constantly slave away after hours and go 'above and beyond' without an ounce of appreciation, but the exact second you show a shred of humanity or arrive one second late, they write you up out of petty spite. It is an insulting, hypocritical environment run by incompetent managers who treat grown adults like undisciplined children. The hours are 7pm-7am, very bad for your health and time. Furthermore, HR will never accommodate personal improvement education, most of the time they wont even answer you or give you an answer that wont help at all. Absolutely useless.
