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.

Pros

Compensation (for higher level associates/senior management positions)

Cons

1) Work/life balance - leaders don't honor paid time off. Many teams expect you to be available during paid time off periods 2) Benefits - employer doesn't offer employer-subsidized vision insurance 3) Holidays - employer doesn't offer MLK Day and Juneteeth as paid days off, indicating how little they value diversity, inclusion, and belonging 4) Promotions - political; not based on merit 5) Mandated 5 day return-to-office to enable "in person collaboration" while at the same time offshoring jobs to cheaper markets. 6) PTO - based on tenure, but I think Lonza prefers high turnover so they don't have to give people time off (if they even honor it in the first place - see con 1) 7) Lack of harmonization - for an established CDMO, I was surprised at the level of misalignment between sites and the lack of standardization of processes
