There's several tech companies that had talks between staff of unionising to 'protect workers rights' when really it was to protect their cushy life.

Our cushy lives should be protected, at gun point if need be.

Unionising nowadays is a sign that instead of using talent to justify your pay, you're using sheer weight of numbers to intimidate the company into not ditching them for fear of negative PR when it could be the best decision for the company.

The only bad tactics are the ones that don't work. Jobs are temporary anyway so might as well bleed the company dry since it's not like you'd have a lasting job anyway.
