What does decertifying mean?
Decertifying is the present participle and gerund of the verb "decertify," meaning to revoke or withdraw official certification from something that previously held it. When a government agency, professional body, or other certifying authority finds that a school, laboratory, aircraft, election result, or individual no longer meets required standards, it may begin the process of decertifying that entity — formally stripping its certified status. The word appears most often in formal legal, regulatory, and news contexts. In the United States, it has a distinctive second life in labour law, where employees may vote to decertify their union, ending its role as their exclusive bargaining representative. Related forms include the verb "decertify," the noun "decertification," and the adjective-like participle "decertified." Because certification signals trustworthiness and compliance, decertifying typically conveys a serious sanction or loss of credibility, making the term useful whenever official approval is being formally rescinded.
Officially withdrawing or revoking certification from a person, organization, product, or union.
"The agency is decertifying several training providers found to have falsified student records."
Often followed by the entity losing certification; common in passive constructions involving regulators or boards.
The process or act of removing official certification from something or someone.
"Decertifying a union requires a secret-ballot vote by the affected employees."
As a gerund, it can serve as the subject of a sentence, often in legal or procedural discussion.
In US labour law, workers themselves can trigger decertifying their union — by majority vote, employees can strip the very organisation that represents them of its official bargaining status.

Etymology of decertifying
"Decertifying" derives from "decertify," formed in English from the prefix de- (indicating removal or reversal, from Latin) combined with "certify." "Certify" comes from Old French "certifier," from Medieval Latin "certificare," ultimately from Latin "certus," meaning fixed, settled, or certain. The de- + certify pattern follows a productive English convention for forming verbs of reversal, as in "declassify" and "decentralize." The word emerged alongside modern bureaucratic systems of official certification, particularly in twentieth-century American administrative and labour law.
