Retail, Wholesale and Department Store Union President Stuart Appelbaum mailed New York City Mayor Michael Bloomberg today knocking his long-standing opposition to living-wage laws.

The letter comes as the city Council is considering a wage-mandate law, a provision opposed by a coalition of business groups.

The Fair Wages for New Yorkers Act will help lift retail workers out of poverty. As you know, the proposed legislation would establish a living wage for workers in large taxpayer-subsidized development projects. Similar legislation is already successfully in effect in a number of cities and municipalities across the country. Workers in those cities earn more and there has been no adverse impact on job creation or development.

The City Council is set to vote on the living-wage bill Thursday, but it is opposed by small business groups and larger retailers.

Here’s the letter:
