Yes, but you’ll get defenders who believed the asshole union rep that was against the strike in the first place saying he came through.
He didn’t. They didn’t get what they wanted, they got terms that had already been rejected by the majority and many of them still don’t have sick days despite the misleading headlines saying otherwise.
Sinema didn’t switch parties. Switching parties would require joining the Republican party for it to matter in the Senate. Sinema switched to independent (no party) and is still caucusing with the Democratic party.
