Conventional wisdom has long proclaimed that moss clumps grow on the north side of a tree, but this is only partially true. In the northern hemisphere, the Sun shines from the south, which means the north side of a tree trunk is typically the shadiest.
The Teamsters joined the Service Employees International Union, the largest AFL-CIO affiliate with 1.8 million members, in bolting. The SEIU is a union that AFL-CIO President John Sweeney once headed. They said they were forming a competing labor coalition designed to reverse laborâs long decline in union membership.
These unions are not part of the AFL-CIO. The workers at a particular employer have the right to choose a union to be their exclusive bargaining representative. If they do not like to level of representation, they have the right to decertify from that union and become non-union.
