I recently took a temporary evening part time representing a company that is unionized. This company is is competing against a non-union company. The non-union company has been kicking butt on the playing field but the union company is trying to compete. As far as customers , they DON'T CARE IF A COMPANY IS UNION or NON-UNION and worse yet, the few union people I have run into don't care either . Bottom line - with the exception of a few union bosses , no one cares if your company , store , service , etc. is UNION . UNIONS ARE IRRELAVANT ! NOT EVEN UNION PEOPLE CARE IF A COMPANY IS UNION !
The only aspect of a strong union that seems to be constant is , that one who is union gets more money than thier non-union counterpart and therefor , they are a higher expense to the company they work for.
