Pros

Work culture is quite positive to a large extent. Since we deal with lab animals, there is a strong focus on mental health which i enjoyed

Cons

The leadership team honestly is clueless. They are constantly changing their mind on the dumb policies they make. There is also no career path for the facilities team, only lab sciences folks
