Note that union boosters tend to want to push the narrative that all business owners and managers are evil caricatures of greedy capitalists who wouldn't give workers anything but scraps if not for the valiant unions protecting them.

Not saying it's never true, but know when to be wary of union people claiming this and avoiding the point that unions sometimes obstruct efforts to keep the company alive and not lay anyone off during hard times by demanding strict adherence to negotiated agreements on hours and wages.
