Pros
There's a friendliness among people working "on the floor", in operational positions throughout the company. Also, I experienced a lot of trust and was given autonomy from my manager although I don't know if this is applicable in a larger context.
Cons
There are too many high level managers who are too old and have been in the company for too long. They don't understand market needs, employees' needs or how to meet the competition from smaller and more agile companies. Also, the organizational structure is a complete mess. Pearson has created a culture where video meetings have replaced actual work, and where decisions are extremely inefficient. Small and insignificant issues are shared with too many uninformed people, and nothing happens until consensus is reached; as an effect many trivial questions are repeatedly postponed to future meetings. Working within in this culture is frustrating for people who want to get things done, who have the ability to move things forward, who have experience from more efficient organizations and who have visions for the future.
