Pros: the people (we have a community of sorts on linkedin).
Cons: closure of the shrewsbury, worcester, and southbridge sites.
See review for TSI Mason Laboratories. When TSI Mason was acquired by Genzyme Transgenics, as Primedica, we had good benefits and a teamwork mentality. After Charles River Laboratories acquired Primedica, that mentality and some benefits slowly declined. I do retain a small pension benefit, and I wish the corporation well.
