Nearly 600 tech workers at the New York Times have officially unionized, forming the largest tech-worker union in the United States. The results of a National Labor Relations Board (NLRB) election were tallied last week, with the spread 404 in favor, 88 against. The workers join the NewsGuild of New York — which, as the country’s largest journalism union, also represents Jacobin  — and can begin negotiating a first contract.

While many New York Times employees are already NewsGuild members, that didn’t stop the paper’s management from waging an anti-union campaign. As the Guardian reported, Meredith Kopit Levien, the chief executive of the New York Times Company, wrote a memo circulated to staff in January titled “Why a Tech Union Isn’t Right for Us.” Kopit Levien’s message? “In short, we don’t believe unionizing in XFun [the group responsible for product development operations] is the right move. But that’s not because I’m anti-union.”

It’s a familiar line at this point. With support for unions as high as it’s been in decades, bosses at putatively liberal institutions cannot outright admit that they’re anti-union. Instead, they emphasize that their problem is with this union in particular. The only notable thing about Kopit Levien’s argument is that it was tried at a workplace that’s already largely unionized.
