City officials on Tuesday called on two dozen companies that have collectively received billions of dollars of local pension investments to ban workplace discrimination based on sexual orientation and gender identification... The companies named by Thompson included ExxonMobil Corp. and AK Steel Corp. "It's never been our policy to discriminate in regard to sexual orientation or gender identity," said AK Steel spokesman Alan McCoy. "It was simply not specifically spelled out in our equal opportunity policy statement." ExxonMobil strongly believes that is has a fair policy in place when it comes to workplace discrimination. "We have policies that have zero tolerance for discrimination or harassment specifically referencing sexual orientation," said ExxonMobil Corp. spokesman Alan Jeffers.
