Cons
Depending upon your position can require a significant amount of travel. Do more with less resources but expect the same output as before...leads to long hours. Not flexible enough on telecommuting. Too many exceptions to the rule depending upon which department you work in. Inconsistency of senior leadership across the board. Management committee can be indecisive on making strategic business decisions.
