Pros
Even though Charles River is a global organization, there is a lot of emphasis on team work from site to site. Many of my colleagues that I interact with on a daily basis are all over the world (Canada, Europe, Asia, in the US but outside of Massachusetts) but we still work well as a team and support each other to achieve our goals. As a member of the marketing department, I have the pleasure of working with a variety of different groups within the company including operations, sales and the scientific staff. There is also a lot of room for growth within the company. I have seen a lot of my colleagues grow and move between departments when opportunities arise. The company does a great job of retaining employees.
Cons
It can be difficult at times to find a work life balance as the company expects more from its employees without increasing resources. However, this is not unique to Charles River, but a trend across industries and corporations.
