Remember to knock!

“Imagine how you feel when you’re buried under work and a co-worker pops into your office. Maybe it’s just to ask a simple question, but that momentary distraction completely derails your train of thought and productivity. Don’t do that to your co-workers. Even if right now is the perfect moment for you to discuss something, that doesn’t mean it is for them. Take the time to send an email to find out when both of you have a few spare minutes.” —Serial entrepreneur Ilya Pozin in Inc.comFind out more things your co-workers really wish they could tell you.

Keep distractions out of site during meetings

“Ten years ago, there would have never been purses, wallets, or any other personal item sitting on the table during a meeting or business lunch.

Having it out on the table is a sign to those you’re with that they don’t have your full attention.” —Serial entrepreneur Ilya Pozin in Inc.comHere’s some other business etiquette you should know too.

Don’t be nosey

“Avoid being a busybody when someone you work with is going through a personal issue. If a co-worker has been unexpectedly out of the office for a number of days, it’s nice to send a thoughtful note along the lines of, “Hope you’re OK. Let me know if there’s anything you need.” But leave it at that. Don’t pry to find out what is wrong, they will let you know if they want to share.” —Expert Anthony Balderrama for

Introduce yourself to new employees

“Remember what it felt like to be the newest person in the office. Smile at the new person, strike up a very brief conversation and ask him or her to join your group for lunch.

Check in with them after the first week or two, when they may be less overwhelmed and appreciative of a friendly face.” —Etiquette expert Debby Mayne in The Spruce

Give people a heads up if you are running late

“While it’s impossible to always be on time, it’s important to let people know you’re running late. For every minute you think you’ll be late, give two minutes warning.
