To remind us – as if we needed reminding, as we vainly strive for ‘inbox zero’ – of just what a time drain email has become, Kay Woodward, UK-based author of What Would She Do?, has wryly channelled one of her book’s real-life heroines, Emmeline Pankhurst (and Pankhurst’s movement’s motto) in her OOO. “Deeds, not emails. That’s what the Suffragettes need. And let’s face it, I’m probably in prison anyway, so couldn’t reply even if I wanted to.”
That’s just sloppy. We always check who will be available, because usually someone is. We also have a service address, and usually use that for OOO–messages. Then the ones working are responsible for those messages. That said, in my branch nobody seriously awaits an answer in July, but I’m in academica.

I want to be clear that I don’t think OOO responders are the solution to the larger problems of worker inequality or the broad American cultural attitudes that celebrate and encourage overwork. That would be silly. The big remedies for what ails modern work will likely require workers organizing and employers recognizing and granting protections. Large companies will have to stop prioritizing shareholder at the expense of their workers. I’m aware how unlikely this feels in practice and how a thoughtful auto reply email feels like applying a band-aid on a gunshot wound. I get it.
This makes a lot of sense to me, since surely in the 3-4 months people tend take as leave in the US, your issue would have been resolved. Also for parental leave, most people delegate ongoing projects to some specific person, so anything that’s still going to be going on months from now when you return is getting handled by someone else.
