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.
Right?! If it’s a 3 day retreat, that’s one thing. But not being around for an hour or two shouldn’t be any kind of BIG DEAL.

World War I – known at the time as “The Great War” - officially ended when the Treaty of Versailles was signed on June 28, 1919, in the Palace of Versailles outside the town of Versailles, France. However, fighting ceased seven months earlier when an armistice, or temporary cessation of hostilities, between the Allied nations and Germany went into effect on the eleventh hour of the eleventh day of the eleventh month. For that reason, November 11, 1918, is generally regarded as the end of “the war to end all wars.”
Ha – I didn’t watch the video but still definitely get the condescension! It’s a LOT of extra explaining and direction when something like, “if you need immediate assistance, please contact Fergus at…” will do. In my opinion, cutesy stuff like this is mildly entertaining at the beginning but gets dumb/annoying shortly thereafter. Not just with OOO messages, but other instances where companies try to make being “cool/funny/laid back” parts of their brand in really obvious ways.
