Cambridge has historically promoted managers less for their competence and management skills, and more for their ability to say "Yes, Sir" and "how high." About 90% of all day-to-day problems stem from a team of inexperienced supervisors who are openly mocked on the floor. Even when trying to handle situations well, every few months upper management will come down with a new decision that simply demonstrates middle management's lack of power in any situation.
Besides that, the job is uninteresting and unchallenging, promotions are rarely given after one year of employment, HR openly talks about things said in private meetings, and the CEO openly celebrates layoffs in firm-wide calls that the hardest-hit departments have to participate in.
No one is happy, everyone is trying to get out, and the firm underpays compared to the market.
