The New York AFL-CIO on Monday launched a digital ad campaign in support of changes to how gig economy workers are classified.

The ad is the harbinger of a larger debate coming over the labor benefits of workers in the on-demand field, like Uber and Lyft drivers, and others who provide services through apps.

“The ads point out that because app companies misclassify their workers as independent contractors, the workers are deprived of statutory rights and protections including: minimum wage, overtime, workers compensation, unemployment benefits, the right to join a union and protection against discrimination and sexual harassment,” said Mario Cilento, president of the New York State AFL-CIO.

The ad comes after state lawmakers last week held a public hearing in Albany on the issue.

Also last week, a coalition of business groups and local chambers of commerce formed a coalition in support of the gig economy, which they say provides workers with flexibility to earn additional money outside of traditional jobs.
