BOSTON -- Massachusetts General Hospital is one of several Boston-area businesses named to the Top 100 list of Working Mother magazine's best companies for working moms.

It was the only local hospital to make the list and it's the third time MGH has grabbed a spot on the list.

The magazine bases its list on more than 500 questions covering issues such as compensation, child care and flexibility programs, leave policies and more.

Particular weight was given to family-friendly policies, flexibility, leave policies and benefits for part-time employees.

MGH programs that particularly impressed the magazine included child care options offered by the hospital, parenting and child care workshops, fitness and wellness programs to keep working mothers healthy and family-friendly policies that allow working moms flexibility in choosing part- or full-time employment.

“Our working mothers are one of our most vital resources,” said Jeff Davis, senior vice president for MGH Human Resources. “They fill many important roles that ensure the hospital continues to run smoothly, and many of them are truly around-the-clock caregivers, tending to the needs of patients here and then returning home to care for their families."

Other Boston-area employers that made the list included Arnold Worldwide, in Boston, Bain & Co., Boston, The Boston Consulting Group, Boston, and Harvard University, in Cambridge.

"The Working Mother 100 Best Companies know that their investment pays for itself through employee loyalty and they realize that productivity depends as much on satisfied staffers as on smart processes,” said Suzanne Riss, Editor in Chief, Working Mother magazine. “By helping employees manage their work/life demands, the winning companies are creating a highly motivated workforce.”

Ninety-nine percent of this year’s winning companies support part-timers by offering them health insurance, while only 39 percent of companies nationwide extend the same benefit.

It's a win-win situation for the mom and her employer, the arrangement cuts costs for the company and gives the employee the work/life balance she needs, the magazine said.

This year’s winning companies haven’t forgotten about working dads either, the magazine said. Seventy-five percent of the 100 Best offer paid paternity leave versus 13 percent of companies nationwide.

“Any business leader who chooses to ignore the driving force in the economy that working mothers provide, does so at his or her own peril,” explained Evans. “With working mothers playing such a strong role in national politics and in business this year, the Working Mother 100 Best Companies are doing all they can to help women attain the top spot in their professional lives without sacrificing their families.”
