New York’s private-sector service unions have been going gangbusters — inking two great deals for their workers in two months. Congrats to them. The danger for New York is that public-sector unions will point to these agreements in their own negotiations.

The latest deal came last week, with the Service Employees International Union winning raises for 10,000 private-security officers who staff such buildings as Rockefeller Center and the Bank of America tower. The guards — nine of whom died on 9/11 — will get 3 percent annual raises over four years, bringing the average up to $19 hourly, or almost $40,000 a year, plus better vacations and benefits.
