Hundreds of volunteers in New York came forward to be part of an outreach campaign to educate thousands of manicurists about their rights and encourage them to take care of their health. The campaign was organized by city officials for nail salon workers.

According to city officials, the day saw visits paid to more than 1,000 nail salons in the Bronx, Brooklyn, Manhattan and Queens. Fliers and packets of information were carried by the volunteers as well as city employees to help manicurists know about wages, their right to paid sick leave and the ways that can help them stay away from potentially harmful chemicals in nail products.

An investigation showed that widespread exploitation of nail salon workers and serious health problems suffered by many of them. After the investigation was published by The New York Times two weeks ago, the administration of Mayor Bill de Blasio, a Democrat, called for the effort. Blasio called it a Nail Salon Day of Action.

Subway stops were chosen to being the campaign along with street corners across the city where manicurists gather before moving to their respective salons for a long day of work.

Nearly half-dozen volunteers were seen carrying fliers half-dozen volunteers in Flushing, Queens. Julie Menin, the commissioner of the city’s Consumer Affairs Department, was also walking with them to support the campaign.

The administration of Gov. Andrew M. Cuomo, a Democrat, has brought new rules for nail salons, like requiring workers wearing gloves. Jenny Guo, 31, is a worker in salon and said that the changes are welcoming, especially those relating to ventilation and safety measures.

She said that wearing gloves would increase safety of every salon worker, as many customers have fungus posing the threats of infection.

Amit Bagga, the deputy commissioner of the Consumer Affairs Department, said that she has come from China and has seen that immigrants are kept deprived of education in the states.
