Sanofi reviews

Management and mid-level supervisors make sure that the employees are aware they don't trust them to get the job done by constantly checking up on each project. When employees know they're not trusted, they become experts at "presenteeism"—the physical appearance of working, without anything getting done. Management keeps their employees in the dark about important, possibly career-altering changes until the very last minute. Marketable top performers want a seat at the table and won't stand for being left in the dark without the information they need to do their jobs well. You will not advance in the company unless you know someone. Advancement isn't based on job performance, it's based on who you know in this company.

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.
