What have we been saying at the Center for Union Facts for years? Rules that prevent incompetent employees from being dismissed are bad, because employers need to have flexibility to fire underperforming individuals. It’s good for consumers, it’s good for businesses, and it’s good for the economy.

We’re glad to see that the United Federation of Teachers agrees! But we’re sad to see that they only think they should have the ability to fire poor workers and that nobody else should:

In a move of stunning hypocrisy, the United Federation of Teachers axed one of its longtime employees — for trying to unionize the powerful labor organization’s own workers, it was charged yesterday.

Jim Callaghan, a veteran writer for the teachers union, told The Post he was booted from his $100,000-a-year job just two months after he informed UFT President Michael Mulgrew that he was trying to unionize some of his co-workers. …

“I told him I want to have the same rights that teachers have,” said Callaghan, 63, of Staten Island. “He told me he didn’t want that, that he wanted to be able to fire whoever he wanted to.

“Stunning hypocrisy” is right. Given the evidence that there are few things more detrimental to the development of a child than having a bad teacher, it’s imperative that school districts be given wider latitude to get poor-performing educators out of the classroom and away from our kids — the same kind of latitude that Mulgrew covets for his massively bureaucratic organization.
