I agree with the previous post 100%. Ford, like any company, must turn a profit to stay in business. They must satisfy Wall St and their shareholders. The post also says this isn't about politics, very true. It doesn't matter if Trump or Biden is in office, it would happen anyway.
The UAW, as nearly all unions, have been irrelevant for nearly 40 years. Ever since President Reagan broke the air traffic controllers strike (PATCO) back in the early 80's, unions have been in decline. Not much leverage anymore.
