4 state-of-the-art child-care centers located near Pfizer offices make it easier for employees to check in on their kids during the day.

With health and fitness centers in 12 locations and gym discounts nationwide, this New York City–based pharmaceutical firm helps employees get in fighting shape so they can better handle the tasks facing them at work and home. Pfizer also helped employees firm up flabby career plans last year by launching a leadership development initiative for female managers and directors, as well as an array of new mentoring programs—like one in the Global Manufacturing division that features small group discussions. Moms seeking further education to climb the ladder can tap up to $10,000 in annual tuition reimbursements and an allowance for books and supplies. A brand-new Mobile Work policy allows users to telecommute with Wi-Fi cards and phone forwarding technology; they can even reserve “Pflex” workspaces at larger offices (with just an hour’s notice) when they need a desk.
