Quite a few people I know have (or are in the process) of changing jobs.
Most of them would love to take some time off in between, but they can’t.
Most of their new employers would love for them to show up on day one refreshed and ready to go. Which is difficult to do if you finish one job on Friday and starting a new one on Monday.
Which begs the question, why don’t companies pay you to take some time off before starting?
Even a few days could make a huge difference.
