What makes it so great?
The clinical research and consulting firm allows employees to take a "QDay" once a year, between October and December; QDays are used for employees to give back to their communities, whether that be by planting trees to preparing care packages for troops overseas. "Everything about Quintiles makes it a great place to work. The people, atmosphere, and core goals are unparalleled," says an employee. "I work from home, which helps me to balance work and life." With programs like "iQ" -- an internal communication intranet that keeps staffers up-to-date with all information concerning the company and industry -- and an almost even gender ratio at the executive/senior management level (50.1% of these positions are occupied by women), Quintiles knows how to keep its people happy.
