Listen, I’m thrilled that the workers got their sick days and credit where credit’s due to anyone in the admin who helped secure that, but that doesn’t make my point inaccurate. The Biden administration helped deny railroad workers their right to strike. That counts as breaking the back of the strike, even if after breaking their back they turned around and gave them (at least part) of what they were asking for. Breaking strikes via a literal act of Congress is a deeply upsetting, dangerous, and anti-worker move. Full stop.

In contrast to the IBEW statements you’ve quoted up above, look at the contrasting tone from the RWU in a recent Jacobin article:

RWU made crystal clear by our words and actions throughout contract negotiations that, while we were of course in full support of seven days of paid sick leave for railworkers, RWU would never be in favor of any legislation denying railroad workers our human right to withhold our labor when all else fails in our struggle for safe working conditions and dignity, regardless of whatever concessions may be dangled.

RWU was and is in favor of any legislation that would grant any relief to the barbaric working conditions we contend with — but we would never concede our right to strike. We thank Ocasio-Cortez and other members of the House of Representatives and the Senate for their votes in support of sick leave. But we are not happy at all with her or others in both chambers who voted to deny railroad workers the right to strike.
