Read the article. The UAW has just signed a ~5 year contract, expiring in 2028. He’s calling for other unions, between now and then, to align their contract expirations with the UAW’s. This is not something that’s possible to do in a short period of time, because it relies upon various other union contracts ending, and realistically by the time we get to 2026/2027 no union is going to sign a sub-2 year contract.
It’s kind of dumb, I kind of think they’re doing it for PR, but it also is a reasonable strategy.
