"What will the boss say?" That's a top question on employees' minds when they're planning for a family. And about 70% say it's actually affected the timing of that first little bundle.

It's just one of the surprising findings from a recently released survey of new and expectant working parents: employers play an unexpectedly prominent role in family planning.

2016 Modern Family Index: The Sting on Careers After Children

Despite an ongoing national conversation about family friendly workplaces, the 2016 Modern Family Index survey shows that women -- and men ; continue to worry about what happens to careers after children. And it turns out, for good reason. Many expectant parents have seen their colleagues passed over for promotions when they have children; others have seen careers stall. And many, after having children themselves, are feeling the sting on their own careers.

Feeling Passed Over, Looking to Leave

Highlights of the data:

• More than one in three new parents report feeling that their boss presumes they are now less committed to work and would prefer if they left
• Women aren't the only ones facing workplace bias; new fathers reported being judged negatively by their peers and bosses and say that becoming a parent will cause them to look for a new workplace
• Workplace bias has had such a major impact on new parents that nearly half have sacrificed salary for a family-friendly workplace and more than half are likely to switch jobs

Third in a Series Series Showing Workplace Bias

The 2016 Modern Family Index is the third in a series demonstrating examples of workplace bias after parenthood. The first revealed that working moms and dads feel they can't be honest with their supervisors about family responsibilities, and worry that family responsibilities could even get them fired. Last year, the survey showed that working parents are experiencing burnout due to the stress of managing their work and family responsibilities, and feel their employers don't care about them.
