For many roles, of course, the sort of OoO described wouldn’t work. But there are a lot of roles where people would survive just fine letting their requests sit for an extra week before forwarding again. And especially at smaller companies where there they might be pressed for coverage when people are out, I think it’s great to normalise that a job is basically ‘off-line’ for a week or two so that the employee can rest and recharge.

There’s a department at my workplace where this is common practice too. My old department worked with clients in similar ways, and I was half expecting we’d also be required to do it, but luckily that never happened. Further proof that, at this (generally progressive, flexible-working) company, your actual work-life balance heavily depends who manages you.
