 Teamsters Local Union 8, which represents technical service employees at Penn State University, has voted to authorize a strike. The union represents 2,700 workers at the university who work in custodial service, emergency medical response, food and housing, airport services, and trades. The vote allows the executive board of the Teamsters to strike if an agreement can't be reached by Sunday. Bargaining sessions began in early May, and the two parties have met nine times since then to try and work out a new deal.
