A new proposed rule from the US Department of Labor is taking another look at the status of independent contractors—and making some in the travel agency channel nervous.

It’s the second time in two years the Department of Labor has revisited the way companies define “independent contractor.” Their goal, they say, is to put an end to the misclassification of workers—”a serious issue that denies workers’ rights and protections under federal labor standards, promotes wage theft, allows certain employers to gain an unfair advantage over law-abiding businesses, and hurts the economy at-large. Misclassification denies basic worker protections such as minimum wage and overtime pay and affects a wide range of workers in the home care, janitorial services, trucking, delivery, construction, personal services, and hospitality and restaurant industries, among others.”
