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
