Mayne not all Teamsters, but thousands got laad off practically on Day 1 when Biden’s handlers cancelled the Keystone XL pipeline.
Biden screwed over a lot of labor when he did that. In the Beaumont/Port Arthur area of Texas there are a lot of union workers in the refineries and chem plants. The Keystone was supposed to deliver a lot of Canadian crude to the refineries there. Several of the plants were in the process of expanding to handle the new workload, then biden cancelled the project, which put a whole lot of union folks out of work.
