I mean, this is what I pretty much did upon returning from my maternity leaves but I would never put it into an email! My maternity leave OOO was the vague “I am on extended leave and am not anticipated to return until X. Please contact Joe or Fergus in my absence.” X being a vague time-frame based on my due date and the length of my leave. No one is waiting 3+ months for an answer so I did get to delete most of the 500 emails I got during my most recent leave! I did once have someone internal tell me I should say maternity leave rather than leave, but really, what does it matter? I’m gone for a few months and no one outside of the company really NEEDS to know why.
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.
