Nationwide, the National Partnership for Women & Families reports that adults without paid sick leave are 1.5 times more likely than workers with paid sick leave to go to work with a contagious disease.

“Knowing the lay of the land can provide parents with reassurance and confidence at what can be a stressful time of year,” says Vicki Shabo, vice president at the National Partnership for Women & Families. “All parents know that there are times when missing work is unavoidable, so knowing whether [they] have paid sick, vacation or personal time to use, and understanding employers’ rules about providing notice for using that time, is also important.”

The fight for paid sick leave requirements has picked up steam since San Francisco passed the nation’s first local paid sick leave policy in 2006. D.C. followed suit two years later, according to the National Partnership for Women and Families.

However, testimony from Kevin Trapani, CEO and president of The Redwoods Group, and Maryella Gockel, flexibility leader at Ernst & Young LLP, demonstrates that such worries are misguided. Indeed, for these employers, as well as for businesses in the states that have passed paid family leave insurance laws (California, Rhode Island, and New Jersey), there has been no evidence of what witness Vicki Shabo of the National Partnership for Women & Families called the “parade of horribles”—a litany of negative business implications predicted by critics.

But that was the culmination of a difficult, nearly nine-year fight. “In the early 80s, when it was first introduced, nobody was even uttering the words work/family policy or work/life balance,” said Debra Ness, president of the National Partnership for Women & Families, which played a big role in crafting the FMLA.

If the bills become law, it would mean that more than 300,000 additional workers gain the right to take up to five paid sick days a year, according to the National Partnership for Women and Families.
