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.
There ought to be a word - and perhaps there is, in German - for the mix of feelings that accompanies composing and activating a holiday out-of-office message. There's smugness, of course, and a gratifying sense of laying down one's virtual tools after a horribly long shift. But for many of us, these nice feelings are tempered by the knowledge that in two weeks, refreshed but depressed, we will have to trawl through hundreds of emails, many of which will be conference room notifications for meetings about crises that have passed.

I’ll be unreachable for a few days starting on December 11th because I’ll be at Growth Marketing Conference. I’ll have limited ability to return phone calls and emails until I return on December 13th, but if you want to talk accounting software options or learn all about the latest growth marketing tactics and tips when I return, please shoot me an email. I’ll get back to you as soon as possible. If you need immediate assistance, please contact my assistant Megan White at 971-841-0098, or at [email protected].
