Are labor laws the same for all industries?

There are basic labor lawas that are nationwide, then you get to labor laws that are for each state that are at least as restictive as federal law, then you get to industry specific laws. An example of this would be the fact children under 18 can't work cerrtan machines in the aerospace industry

No, not in the US, nor, uniformly, in all 50 states.
NY, for example, holds contractors to a much higher standard of liability under their "ladder law," which assumes that any contractor whose worker falls off of any ladder (including a chair, an overturned bucket, a stack of books) is automatically liable for that worker's injuries - and the contractor has no common law defenses. (This is known as "absolute liability," or "strict liability.")
Certain industries must follow "affirmative action" guidelines in certain fields if they do any work that has any federal funding.
Certain states allow unions a free hand in striking and bargaining, even if 49% of that firm's work force don't want to be represented by that (or any) union - in some states, they can be compelled to pay union "dues," whether they're a union member or not.
Labor laws can also differ by age (you can only be a victim of "age discrimination" if you're over 40), by race (only certain ones are "protected," in some instances), and in general, men cannot be sexually harassed, as defined by our Supreme Court. (ie, men are not able to collect for being sexually harassed, unless both they and their supervisor/harasser are homosexual.)
So yes, labor laws can differ quite a bit!
