Guess they haven't stepped up

Remember when all of these individuals signed a pledge that said they would support this?

We’re stuck here in New Orleans, too. Stuck with promises from politicians that haven’t materialized in our paychecks. I believe strongly that public money must be used for the public good and that means that jobs using public finances must pay fair wages. During the last election, six of our city council members and the mayor said they agreed and committed to supporting a $15 minimum wage. It’s time they acted.

Why haven't they?
