Hundreds of union workers jammed Assembly Chambers, spilled out into the Loussac Library lobby,and outside Wednesday night for an Assembly hearing on Mayor Dan Sullivan’s plan to limit the power of city labor groups.

Sullivan’s proposal, if approved, will take power from city unions to strike or arbitrate disputes with the city, making the Assembly the final decision-maker. It eliminates raises based solely on longevity, or performance bonuses. And it limits raises to a five-year average of the consumer price index.

The mayor says the current labor law is out of date, and he wants to control labor and administrative costs. 

The plan is to come up for Assembly action on March 12.
