One software company I worked had a benefit that, in your sixth year, you could take a paid sabbatical. IIRC, it was a month, which was still a nice break, but you probably aren't going to have time to write a novel.

I heard of people using that sabbatical to pick up consulting work. (This was before FAANG salaries, so even top engineers and managers might need the extra money, such as for kids' college, more than they need to travel or take up watercolor painting.)

Professor friends who've done sabbatical, it's much longer than a month, and seems to be a change of working scene. There's no teaching load from their university, but expectations that they'll be doing research/writing of some kind. They might do it while visiting a different university.

Regarding the class equity the article mentioned, a paid contiguous month off might be something a company could swing for all employees, as acknowledgement and incentive to stay 5+ years. A paid few or more months off would be a different matter to do.
