NEW YORK, NY June 23, 2006 —Twenty labor unions representing more than 170,000 city workers have banded together in a new coalition, pledging to bargain together to preserve their benefits.

REPORTER: Teachers Union President Randi Weingarten says the unions are worried about the nation-wide trend of cutting healthcare and pensions.

WEINGARTEN: And what has happened is that you have a lot of people behind me who have been watching this, thinking about it and very much believe collective action is the way we can create fairness.

REPORTER: Mayor Bloomberg hasn't said if the city will recognize the new labor coalition. But on his WABC radio show this morning, he said "one size fits all" fits no one, suggesting the 20 labor unions have different work rules and might not be served by working together.
