Pros
Flexible work hours. No one really cares whether you're doing your work or whether you're even showing up at the office. Hurray.
Cons
Working at Pearson was like walking through peanut butter. Nothing ever gets accomplished and you are always mired in bureaucracy where the right hand doesn't know what the left hand is doing and most likely doesn't care anyway. This can be bad if you actually care about what you are doing at your job or need to have meaningful outcomes. Eventually you find yourself arguing about data with your neighbor and wondering how you got there. There are no career opportunities that I could see of and I couldn't figure out who was really running anything so I could schmooze my way to the top. Luckily I got laid off before I got too old to be employable but just barely.
