Aside from "watchdog" as opposed to NLRB, what's wrong with the title? The article describes a bunch of required actions besides just deleting the tweet.
Not the original commenter, but personally, omitting NLRB would be my main concern with the title. A "watchdog" seems needlessly vague as it could imply any range of organizations that report on this, but the NLRB is the specific agency tasked with overseeing and enforcing these union representation laws on a federal level.
I thought the register article was written in a clickbait way.
Reuters actually had the scoop over 24 hours before the register.
