Shouldn't employees have the right to collectively strike to get better conditions at work? There's a lot more at stake here than "drama for the company".
Doesn't the employer have the right to fire them for any reason in any "at will job"?
I am not sure if that is true or not or if it applies to google employees, but I feel like there is a ring of truth in it.
While it's harder to get fired here, it is by no means impossible. The law just provides what's basically a three strike system (one to two adhortatory letters for the same reason, then the third time the employee can be dismissed) to give the employee a chance to change behaviour.
Striking employees can be replaced in order to get the work done, but that doesn't make sense for a one-day walkout.
