The said "tool" seems to work by flagging almost every word in the English language with a gendered connotation, including "mother" and "father." When users learned about the Inclusiveness Checker and attempted to see how far it would go, they found out that when using the term "maternity leave," the Checker would recommend changing the phrase with "birth-related leave," "parental leave" or "childbirth leave." When referring to "paternity leave," it suggests "child-bonding leave" as an alternative.
When users attempted to input the term "postman," the Inclusiveness Checker would suggest "postal worker." When using the term "manpower," the Checker would recommend replacing the word with "workforce."
