Following the expiration of their collective bargaining agreement with a trade organization of contractors called the Cement League, concrete workers walked off their jobs at an estimated 30 job sites throughout New York City. The workers belong to the union collective New York City District Council of Carpenters.    

Following stalled contract negotiations and a failed mediation attempt, approximately 750 Milwaukee County Transit System bus drivers began striking. The drivers are seeking wage increases and a cap on the hiring of part-time drivers. The striking drivers are represented by Amalgamated Transit Union Local 998.    

Approximately 30 members and supporters of United Auto Workers (UAW) marched to Hyundai’s Fountain Valley, Calif. headquarters in protest of low wages and unsafe working conditions. The march was in coordination with 23 other protests at dealerships across the country.    

President Obama appointed a presidential emergency board to resolve a bargaining dispute between a coalition of 17 unions and New Jersey Transit. The parties are barred from engaging in a strike or lockout for 120 days. A panel of three arbitrators will investigate and make nonbinding recommendations for a new collective bargaining agreement within 30 days.    

After working without a contract for a year-and-a-half, and no closer to settlement, 80 concrete delivery workers represented by Teamsters Local 50 went on strike in Swansea, Ill. The union also filed undisclosed unfair labor practice charges against two companies.    

About 60 short-haul drivers working the ports of Los Angeles and Long BeachCalif., for Pacific 9 Transportation, Inc. began an indefinite strike. The Teamsters, which has unsuccessfully tried to organize the drivers, state that the strike is in response to the company’s continued misclassification of them as independent contractors. This is the seventh strike by shorthaul drivers at these ports in two years.    

Workers at New York’s LaGuardia and JFK airports called off a planned strike, which they had unanimously authorized, after Aviation Safeguards, an airline contractor, agreed to allow SEIU Local 32BJ to begin an organizing drive among the nearly 1,200 employees.
