Pros

Pay and close from home

Cons

Toxic management, an HR department that enables bullying, and a 'feedback' policy that is actually a trap for retaliation. It’s a living hell that ignores every cry for help. Looking for a new role as we speak.

Pros

Not everyone is bad, lots of people keep their heads down and get on with the job.

Cons

Toxic HR who are living in la la land. They all need sacking if Merck is to restore any credibility.
