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
