How are the career growth opportunities on the IT team at McKesson?

Extremely bad. They hire the wrong people to work above you and they have no management skills and no communication skills. They lie to you to keep you quiet. The managers above them only want to hear what they want to hear. I for any reason, whether true or false, they feel that you can't give them what they want, they will walk you out the door right then and there, no opportunity to say goodbye to the others, and fire you on the spot. Don't think that you can save your job by talking about it, they'll lie to you and say it was all because of the budget. The ones that have been promoted, have no clue what they're doing, and they will and have overlooked the good people who should be promoted.

McKesson recently centralized all of its IT (central IT and all BU IT). GIven this, and given cost pressures that will last the next year or two, career growth is worse than normal as there are too many people in IT and there will be reductions. If already there, there is normal growth (promotion) opportunities, but the fact is there are 2-3 people for most leadership jobs at this point.
