Philosophically or legally? I’m fully aware that US has weak worker laws, but in Europe you can’t fire people based on whim.

Employees at Google are mostly at-will. Google can fire them any time, although typically, they produce a 6+ month performance record with failure to do job before terminating (mostly to protect against lawsuits). However, Google has terminated people on the spot, with cause. The government will back Google firing people for not being vaccinated.

The takeaway is that the general left now is for firing employees for political or medical reasons, when historically they were against. Why that is, at least in Europe, is because the left is no longer majority working class, it is majority middle class.
