More and more, working moms are telling their employers that they need and deserve more support - and some companies have really been listening.

Working Mother magazine just identified the 100 best companies for working moms to honor those organizations that are setting the standard for work-life practices in the US.

To compile the list, which is now in its 31st year, Working Mother surveyed hundreds of companies with more than 400 questions about their paid time off and leave policies, workforce profile, benefits, women's issues and advancement, flexibility policies, and company culture, among other things.

Every company on the list offer fully paid maternity leave, and the majority also offer flextime, backup childcare, professional development opportunities for women, mentoring programs, and career counseling.

Subha Barry, vice president and general manager of Working Mother Media, says these companies are also beginning to embrace a number of emerging trends, including wellness programs for employees like fitbits and yoga classes, more support for families with special needs, and benefits to part-time employees.
