Luckily I don't see many oil drilling rigs in NYC

I guess you didn't read the article?

ABC News reported that the ordinance — which will take effect Nov. 22 — excludes cases in which a person’s height or weight makes them unable to perform required aspects of a job.

I guess you didn't read the article, or my point, which is that you can't be fired for being overweight. That's the point.

The article you posted has clear and direct exclusions for jobs where they can have physical requirements - as I quoted directly for you. Therefore even if there were offshore oil rigs in New York, the law would not apply.
