      Be very careful about what you say!

      Pros

      Some of the best reasons is that they are not "corporate" in the sense, that they don't write you up for every little thing. They were fairly flexible with myself as a single parent.

      Cons

      Extremely top heavy in management. For my department we had 3 employees, a manager and a Supervisor. They don't write you up for everything, they just fire you. I wrote an email to my manager about innapropriate behavior between himself and my coworker and that I was feeling uncomfortable, and instead of changing that, they let me go.

      Great potential if not for the rampant toxic culture

      Pros

      - Very nice offices in Reading - Good benefits including free EV charging on-site - Some talented colleagues - especially the "old timers"

      Cons

      - Toxic culture - colleagues smile at you and then give negative feedback to line managers behind your back. - Speaking up is encouraged by SLT but it will put a target on your back. - "My psychological safety" (a buzzword at Sanofi UK) is used as a weapon to complain. - Very high tolerance for under performers. Getting high scores on employee surveys is more important than performance. - HR's only objective is to support the SLT. Have no illusion they are there for you. - Recognition based on who's the leader's favorite, not merit
