Corporations don’t want government to tell them what to do. They pay lots of money to politicians at all levels of government from POTUS to state representatives to make sure they can do whatever they want. These corporations don’t care about people who work them as they are expendable, thus there will be no rules placed on companies that are doing nothing more than keeping plants open to make money regardless of how many of their employees and the citizens in the surrounding community dies.
There was a day when there would have been strikes all over the place, but union busting has mitigated that risk to corporate America.
