Do not intervene
Yes, do intervene
Nonsense. The screwing is done by the unions to the employees. They killed the auto industry and constantly price their people out of the market. Employers look for options like overseas manufacturing or automation. Are the grocery store employs unionized where you live? Notice the automated check out?
And a machine can't stock shelves yet for one, two in the store i work at (or whole foods or trader joes) they don't have automated checkout. And this is another symptom of a deregulated system. Plus theirs still cashiers at a store with automated checkout.
And really the screwing is done by the employer to the employee. The unions are another symptom of a sick system.
