The roughly 180 Steelworkers Union members (out of a total payroll of about 3,800) that work in the refinery division of Brentwood-based Delek (Ticker: DK) are getting a raise and a signing bonus, but it's not as much as they'd hoped for.

The union, which represents 30,000 employees in the oil industry, said it was not able to negotiate for better health and safety conditions.

"The recession had a dampening effect on our proposal for a more significant wage increase," Gary Beevers, the union's vice president and lead negotiator, said in a statement. "Even though the oil companies made record profits the last few years, they used the poor economy as a shield to prevent us from receiving a higher pay increase."
