Just got word from the Service Employees International Union that the custodial staff at the Carnegie Science Center has officially, and unanimously, voted to unionize.

This is no great surprise: All 10 of the custodial staff signed union cards late last year. The only surprise is that it took so long to ratify that decision. As I first reported here, despite the early unanimous show of support, the Science Center forced the staff to hold an election, which wasn't held until today. (The P-G later followed up with a story here.) 

So congratulations to the SEIU and to its newest members, who will now begin negotiating a contract. And congratulations to the Science Center, I guess, for going another couple months without having to pay its custodians health benefits or a decent salary.
