Clear lawsuit? COVID | "nys no longer enforcing healthcare worker covid19 booster requirement"

For context, NYS had a deadline of Feb 21st (presidents day), to get your 3rd dose of the vaccine or you would be fired. State workers had Monday off for the holiday so they had to get it on 2/18 in order to keep their jobs. Then at about 3PM EST this was released saying it was no longer mandated. There was clearly no intention of following through with this. It was clearly an attempt to coerce state health employees into getting the 3rd dose. They even sent out memos saying "Don't even show up to the premises if you did not get the vaccination". How can this be at all legal? Uncontrolled and reckless attitude towards these decision.
