HARTFORD, Conn. (AP) About 800 nursing assistants and other workers at two hospitals are set to vote Friday on whether to establish a union in the latest large private sector organizing drive in Connecticut.

Workers at Danbury Hospital and New Milford Hospital say inadequate staffing and better treatment are top concerns. Pay also is an issue. The union says it ranges between $12 and $20 an hour.

AFT Connecticut is organizing service, environmental, administrative and maintenance workers and patient care providers. It's accused hospital managers of interfering in the organizing drive and the National Labor Relations Board is investigating.

A spokeswoman says Western Connecticut Health Network values each employee and complies with all laws and regulations.

The NLRB says the last large union drive was by electrical workers at the Millstone nuclear power plant last year.
