Three major labor unions, including the Teamsters and the United Auto Workers, say they'll press to unionize workers at Atlantic City's newest casino.

The unions are joining with Local 54 of the Unite_HERE union to start a unionization drive at Revel. Revel's dealers, hotel workers, beverage servers and others are not represented by a union.

Local 54 has repeatedly clashed with Revel over tax subsidies that the $2.4 billion casino has received, as well as four or five-year term limits it has imposed on many customer-service jobs.

Revel opened earlier this month and is Atlantic City's 12th casino. It has reached pacts with some other unions.
