Aircraft manufacturer Boeing has told its union that passage of a gay marriage law in Washington state won't affect pension benefits for gay married couples.

According to Seattle alternative The Stranger, Boeing, which was founded in Seattle and maintains a large number of employees in the state, will likely deny “pension survivor benefits to same-sex married couples.”

Washington voters earlier this month upheld a marriage equality law approved by lawmakers.

In the course of contract negotiations, the company told union representative Ray Goforth that such benefits are covered by federal law and that Boeing does not plan to voluntarily extend the benefits to the spouses of gay employees.

“Their answer was that they had no intention of granting pension survivor benefits to legally married same-sex couples because they didn't have to,” Goforth told the paper. “We are profoundly disappointed that they would use a loophole to engage in institutionalized discrimination.”

In a statement, Boeing backed off a bit saying, “Nothing is ever final in negotiations until they're over. What we said today is that [these benefits] are not currently addressed in the contract.”
