They have different issues. Construction work is hot and cold. Industrial work is regular consistent long term.
Organization:
All construction has similar work units involved: electricians, plumbers, welders, cement workers, iron workers, sheet metal workers, roofers, equipment operators, general laborers. It is run by a general contractor who will usually hire subcontractors to do work he does not specialize in.
I think industrial operations will have fewer divisions within the workforce. Also it is more likely for workers to move around to do different functions in the operation and it probably has to be written into the contract to allow WORKERS TO MOVE INTO A DIFFERENT DEPARTMENT WITHOUT LOSING SENIORITY.
As far as bargaining, I do not know.
Labor relations has to be different. I do not know of labor issues on a construction site other than seeing a company picketed because part of the workforce is non union or they have a labor grievance. Industrial operations generally have the workforce at the same site for more time, so the CONTRACT EXTENDS OVER SEVERAL YEARS RATHER THAN MONTHS TO A LITTLE OVER A YEAR.

Construction unions usually represent higher skilled labor like electricians, pipe-fitters, etc. Wages are usually higher and benefits are better.
