an under appreciated consequence of remote working is the radical reduction of switching costs to a new job.

In the on-premise world, this would require all sorts of calculations outside the immediate considerations of the job itself - the commute, the parking, the new office amenities vs old office amenities, the degree with which you 'click' with colleagues - all of this is reduced or eliminated in the world of remote work. You will be sitting at the same (home) desk, at the same set up, probably using the same tech environment.

It will make switching easier, cos it means less.
