Hey! Buddy! Ya can't do that! All the sanitation workers will go on strike!
The company I once worked for used to do quite a lot of business with New York.
One of the vendors told me the trash collectors were the most powerful force in New York. If the cops went on strike, people would just be more careful about staying out too late, where they went, etc. If the cab drivers went on strike, they'd take the subways. If the subways went on strike, they would take buses. If all three went on strike, they would carpool, bicycle, walk, use scooters & skateboards, etc.
But if the trash collectors went on strike, they had little recourse. There was one clever lady who bought a large roll of store wrapping paper from Sak's, gift wrapped her trash, set it in the back seat and left her car unlocked. It disappeared, of course, but the wrapping paper was getting expensive.
The city's life is numbered in days when the trash collectors go on strike.
