If New York City Mayor Mike Bloomberg is the tough-minded, results-oriented pragmatist that his fans in the media keep telling us he is, here’s his moment to shine:

Selfish Sanitation Department bosses from the snow-slammed outer boroughs ordered their drivers to snarl the blizzard cleanup to protest budget cuts — a disastrous move that turned streets into a minefield for emergency-services vehicles, The Post has learned.

Miles of roads stretching from as north as Whitestone, Queens, to the south shore of Staten Island still remained treacherously unplowed last night because of the shameless job action, several sources and a city lawmaker said, which was over a raft of demotions, attrition and budget cuts.

“They sent a message to the rest of the city that these particular labor issues are more important,” said City Councilman Dan Halloran (R-Queens), who was visited yesterday by a group of guilt-ridden sanitation workers who confessed the shameless plot.

Halloran said he met with three plow workers from the Sanitation Department — and two Department of Transportation supervisors who were on loan — at his office after he was flooded with irate calls from constituents.

The snitches “didn’t want to be identified because they were afraid of retaliation,” Halloran said. “They were told [by supervisors] to take off routes [and] not do the plowing of some of the major arteries in a timely manner. They were told to make the mayor pay for the layoffs, the reductions in rank for the supervisors, shrinking the rolls of the rank-and-file.”

New York’s Strongest used a variety of tactics to drag out the plowing process — and pad overtime checks — which included keeping plows slightly higher than the roadways and skipping over streets along their routes, the sources said.

The snow-removal snitches said they were told to keep their plows off most streets and to wait for orders before attacking the accumulating piles of snow.

A public sector union just refused to perform their duties in a snow emergency to make a point about a contract. If Bloomberg has any desire to run for national office — I think he doesn’t really want to run — he has to show that he can stand up to public sector unions with unrealistic expectations.

How do you deal with a union with unrealistic expectations and no sense of duty to the public? Well, this comes to mind…
