I can’t find a solid confirmation but it looks like as part of the law killing the strike and enacting the recommendations of the emergency board, the attendance rules creating points was vacated without further agreements from the unions. So from what I can tell, your statement is incorrect. I looked up the emergency board’s recommendations but I didn’t do a deep dive into the law to confirm. Link to the recommendations below.

Just so everyone knows. Child poverty went down because Dems had enough power to expand the child tax credit as part of Bidens American rescue plan. The expanded credit then expired and Republicans have blocked passage of the renewed expansion. This is another thing where Republicans will do anything to harm Democrats including voting against extremely popular programs. I agree that it sucks the poverty went back up, but Dems reduced it and Republicans increased it.
