New Choice NY, an outside group informing public sector workers how to legally stop paying their dues, launched a December mail campaign targeting union homes in the area.

Flyers from the group, which waded into the New York debate over the U.S. Supreme Court’s Janus decision, were submitted to the Times Union by a tipster.

“This Christmas, give yourself a raise,” the leaflet reads.

In July, the U.S. Supreme Court ruled that public employees who don’t belong to unions can no longer be required to pay agency fees to fund collective bargaining efforts.

The handouts include information from a recent Empire Center report that found that New York State United Teachers saw a 6 percent drop in the number of people who pay either regular dues or special fees since the Janus ruling.

Still, most public sector workers in New York appear to be sticking with their unions.

In July, New Choice NY sent out an email blast to more than 500,000 New York public sector employees inviting them sign form letter for members who want to leave their unions, sparking a feud between pro- and anti-union forces.

Gov. Andrew M. Cuomo in July ordered the state Department of Labor to issue guidance softening the effect of the Janus decision and has signed legislation making it more difficult to opt-out of membership.

The guidance said: “Public employee unions are not required to produce dues authorizations cards for members from whom the employer has previously deducted dues.”

Bob Bellafiore, a political strategist running the New Choice NY campaign, denied that the group was trying to weaken union membership.

“It’s part of our effort to educate people about their rights and their ability to opt-out,” he said. “We’ve done some press, we’ve done some radio ads and billboards in October. This is just a part of our ongoing educational campaign.”
