I am not so tolerant or forgiving.
There are many demands that employers should never be allowed to make on anybody.
"Private corporations" are naturally inclined towards totalitarian rules and controls. They are as bad or worse than the Government in that aspect. That can be checked somewhat by a "free market" in labor. But larger corporations accumulate too much power and invariably attempt to exert monopoly control over customer and labor markets. In the short run they often succeed.
