Mayor de Blasio’s nonprofit took in $200,000 from a food-service union on the same day a mayoral ally in the City Council submitted legislation to protect the union workers’ jobs, new financial filings show.

Unite Here, a union formerly run by Hizzoner’s cousin that has given more than $900,000 to de Blasio causes, made its latest donation to the nonprofit Campaign for One New York on Nov. 23, 2015.

That was the same day Council Member Ydanis Rodriguez (D-Manhattan) introduced a bill requiring venues such as universities or sports stadiums to retain unionized food-service workers for at least 90 days after ownership changes.

Rodriguez spokesman Russell Murphy dismissed the timing as coincidental and said the council member, who worked in the food-service industry at age 19, has been fighting for working New Yorkers his whole life.
