Pros
My coworkers at Covance were some of the best I have ever had. They made everything else about the job easier to handle day to day. The benefits are okay, but have lost some value with the acquisition by LabCorp. Otherwise, the only good thing I can really say is that scheduling was super flexible with flexible working hours.
Cons
I'm not sure about all of Covance, but working in the Early Development Division in BioA was a tough gig. There is too much work and no one seems to know how to schedule or organize it correctly. There's a lot of rework because of poor planning and lack of effective implementation of new systems and processes. This leads to lack of accountability that means that maybe sometimes the right people are promoted, other times they just aren't.
