Pros
The people working for Pearson are typically educated and professional. Since it is a publishing company you find a fair number of women working there. The environment is professional, but less corporate than other big companies. The company tries to offer work/life balance by offering back up child care as well as family leave act.
Cons
There seems to be a lack of advancement opportunities, and many departments would rather have you work a lot of hours instead of hiring the necessary staff. Hard to get appropriate salary raises when needed, so if you start off with a low salary it will be hard to catch up. I have heard of people leaving, just to come back a year later and make $20-$30 K more. As managers are usually super busy and over-worked, performance appraisals and mentoring of employees seem to suffer.
