Construction industry unions, particularly Operating Engineers Local 150, continue to use the strategy which we regularly refer to as "rats, banners and street theater". They rely on the 2010 Eliason & Knuth NLRB case which gives unions pretty much a green light to engage in secondary boycotts as long as they are not picketing. That Obama Board decision relied primarily on free speech theories. The normal union strategy is to put up a large rat at the premises of a neutral employer that says something like "Shame on You". In other words, there is disruption and demonstration in front of the neutral employer's premises and the whole objective is to have that neutral stop doing business with the primary. For unions, it is a way around the secondary boycott provisions of the National Labor Relations Act. But, with the new pro-business Board now in place, it is likely that this strategy will have a pretty short life expectancy. We anticipate that once the new Board finds an appropriate case they will overturn Eliason & Knuth and find this type of activity to be an illegal secondary boycott. Below is a picture of a typical Eliason & Knuth scene.
The author is fairly certain that a vast number of the readers of this Article have either seen or unfortunately been involved in a case where a union has placed signage and the RAT at an employer's premise to force the employer to "cease doing business with or supplying another employer with raw materials (i.e., stone, sand, gravel, piping, etc.)" with which the union has a labor dispute. The Obama Labor Board (NLRB) has found this type of activity to be "Free Speech" protected by the First Amendment and exempt from the prohibitions of a "Secondary Boycott."
