I am responding to the quotes above; my purpose is not to start a religious discussion, which is not appropriate for this forum, it is to fill out the context of this discussion.
That said, as described in the Old Testament of the Bible a sabbath (Hebrew: Shabbath) day of rest was instituted by God on the seventh day of the week. It was designed for man’s good. Man is to work six days and rest and worship his Creator on the seventh.
As I wrote above, a week sabbath (for me my Think Week) is valuable for deep strategic thinking but even a two day “retreat” to the backyard can be refreshing and valuable. I don’t believe anyone is arguing against a sabbatical/retreat per se. The OP’s point was that most people do not have the time, freedom or financial wherewithal to be taking off work for multiple day retreats or sabbaticals. Those who can are a limited group of individuals whose circumstances are such that they are able to do so. The same can be said about working from home during a pandemic. Some professions can accommodate a work from home option, others cannot. My plumber cannot work from home during a pandemic. I doubt that he can take multiple day retreats or sabbaticals without going broke. Having lived for eight years on a farm I can tell you that dairy farmers can’t take sabbaticals either.
Again, back to the OP’s complaint that too much is said about sabbaticals on the Focus and MPU podcast, I don’t think that is necessarily the case, especially for the Focus podcast. The idea of sabbaths, sabbaticals, or retreats is to withdraw from the whirl of daily activity and work to rest and to focus on one’s personal and professional callings and growth. This is the purpose of the weekly Sabbath described in the Bible: rest, reflection, worship, and restoration for the next week. This is extended in the Old Testament with the year of Jubilee. The Year of Jubilee was a year full of releasing people from their debts, returning property to who owned it and as a year of rest (not idleness). The idea of taking time away from the grind of the everyday is perfectly appropriate for the Focus podcast. If some feel like it is covered too much, just skip forward during the episode.
In short, a discussion of of sabbatical and retreats is perfectly appropriate for a podcast titled Focus but, to the OP’s point, most people are not in a position to take multiple days off to do so, those who can are a small niche group.
