Pros
Pfizer has great benefits and is family friendly. Pfizer recently formally enacted flex hours so most professionals are off on Fridays or at least Friday afternoons. The vacation plan is decent and the medical coverage is excellent with free prescription drugs and low copays for the doctor. I found that local managers are willing to work with you to accommodate time off for family matters. Professionals can set their own start times each day to get home before the school bus. Like I said really family friendly. I've taken time off during the day to attend a school activity and just worked later in the evening.
Cons
There is a paranoid feeling about the whole place. Every year brings another round of layoffs. Every business unit seems to get hit by these layoffs with strict percentage cuts now matter how lean the group was before the layoff announcements. Also pay increases are running less than inflation for the past four or five years. A worker in their twenties would be hard pressed to make a career in the current environment. Everyone has lost a good friend to the downsizing and the age of an average worker gets higher every year because of the hiring freeze in place.
