Pros

Great benefits with 5 weeks paid vacation without having to accrue time. Also up to 3 months of paid parental leave. They have medical, dental, vision and group legal that you can opt in for. They also have a variety of wellness benefits such as personify health which pays you up to $225 a year for maintaining healthy habits and Lyra for mental health support.

Cons

It's a big company that moves pretty slowly. Not a lot of opportunity for development outside of my role for the group that I work for. Currently going through a lot of organizational changes.

Pros

Merck has been an excellent company to work for, for the over 10 years I have been here. Colleagues are nearly always willing to lend a helping hand or take a break to answer a question and provide guidance. I recommend anything considering a position here to take it!

Cons

There can be bureaucracy, but they are taking steps to mitigate it. Different in every organization I'm sure. It's a 100+ year old company, to be expected.
