Depressing and toxic

Pros

I’ve been with this company for over a decade, but lately it feels more like a trap than a career. The culture has deteriorated rapidly, especially after the abrupt and demoralizing return to site mandate that felt more like a punishment than a policy. The environment is tense, disjointed, and disheartening. The only thing keeping me here is the health insurance otherwise, I would have moved on already. If you’re thinking about applying to Lonza, I’d recommend holding off, at least until the organization re-evaluates how it treats its people.

Cons

Management is siloed and often plays favorites, creating a toxic atmosphere where retaliation isn't uncommon. Decisions are reactive, not strategic, and forethought is practically discouraged. The pay is decent, but it comes with a heavy emotional toll. After a while, you’ll start dreaming about work and wondering if your growing collection of bourbon bottles counts as a hobby or a warning sign.

Good and Bad

Pros

- Hands on testing experience - Cross Training - Some Good co-workers - Available overtime - 401K

Cons

- Silo Mentality - Manager rivalry - GMP Violations - Poor Building infrastructure - Toilet flooding multiple times leaking raw sewage into GMP lab and office areas (deemed normal with facilities and EH&S) - Petty bathroom etiquette training by microbiology manager - Dangerous area of town. Foggy conditions, risk of getting hit by trucks while walking from building to building - Matriarchy power trip among some women there against men in their group. They feel threatened by new people. Some women there were ganging up on myself and others. There is a tendency to make something from nothing.
