Pros: good pay and benefits, stability
Cons: upper management "thrash", tiny cubes offering no privacy
McKesson is an enjoyable place to work, allowing employees work hour flexibility to provide some measure of work/life balance. I was fortunate not to be working on the "cutting-edge" products where much longer hours were expected, although I did work on some intense short-term projects too.
My McKesson co-workers are, with almost no exception, bright, personable and hard working.
First level managers dothe best job they can, but they were so often required to act as Product and/or Project Managers that they did not
Upper management, on the other hand, changes personnel frequently and changes priorities, and focus, with each "thrash".
