What we need in our work communication is not more professional politeness or less formal, chat-based messaging applications like Slack. We need honesty. The problem is that we’ve conditioned ourselves to see honesty as self-indulgent or disrespectful. I’d argue the opposite is true. Honesty, even if it’s a bit more inconvenient for all parties in the moment, pays dividends later. It builds trust. When my partner Anne Helen Petersen and I were interviewing people for our forthcoming book on remote work, a frequent lament from both middle managers and workers was that they didn’t feel like they knew how to succeed in their jobs; that they were guessing what their superiors and coworkers wanted and, even when they asked, they didn’t quite trust the responses they got back.
Like the previous examples, the message doesn’t have to be lengthy – you just need to let people know the details, and who they should be contacting in your absence.

We do it every time we go on vacation or take a sick day. We put up an out-of-office (OOO) message with the date of our return, a colleague’s contact information for urgent needs, and maybe even some details about the destination of our long-awaited vacation.
“You have reached [Sandy and Bill’s] voice mail. Please leave your message after the beep so we can call you back if we want to.”
