The results of the annual survey by the American Psychological Association found that 32 percent of women said employers didn't provide enough opportunities for internal advancement, compared with 30 percent of men who said the same thing, ABC News reported.
Out of the 1,501 employed adults surveyed online, 32 percent of the women said they received sufficient monetary compensation for their work, compared with 48 percent of employed men.
Women found another level of stress if they had families, even if it just came from a "stereotype threat," according to the Wall Street Journal.
Pilar Clark, a blogger on the parenting website Babble.com, which is owned by the Walt Disney Co., the parent company of ABC News, said many women felt added stress from the minute they announced they were pregnant.
"It's ridiculous, but there is real fear of losing your job throughout a pregnancy that creates an enormous amount of stress and tension," Clark said.
Clark said that new moms can face resentment when they return to the office.
While the Pregnancy Discrimination Act of 1978 and Equal Employment Opportunity Commission prohibit discrimination against expectant mothers or discrimination on the basis of gender, Clark said that employers can still find ways to replace a mother on maternity leave.
Clark, 32, said when a new mother returns to the office, there may be "eye rolls" over what is deemed to be special treatment, which might include a flex schedule, telecommuting, leaving early to take care of a sick child.
