...but this link below suggests there is not really a union for some park workers, here's a clip from the article:
60 employees of the Boathouse Restaurant in New York’s Central Park walked off their jobs on August 9 and were joined on the picket line by 37 of their co-workers who were illegally terminated in retaliation for organizing a union. Boathouse workers began organizing in 2009 because of very low wages, stolen overtime pay, long hours, no benefits, unsafe conditions, rampant favoritism, sexual harassment, ethnic discrimination, and extremely abusive managers.
