The rules of business etiquette have changed over the years, but there are some things that have stayed the same. In a professional work environment, maintaining good etiquette is key to good working relationships, and it’s one way to show that you respect your boss and co-workers.

Here are some of the basic do’s and don’ts of professional business etiquette.

Be on time for meetings

Being habitually late for meetings is a sign that you don’t respect your boss’ or your co-workers’ time. Be sure to wake up early enough so you will have time to go through your morning routine and still make it in time for your meeting. If you’re meeting a client at a restaurant and know that you’re going to be late, call and apologize, and give him or her an idea of when you’ll be arriving for your meeting.

Turn off your cell phone during meetings

Constantly checking your phone or texting during meetings is a no-no. You should give your boss or your client your full attention, so make sure to turn off your phone or put it in silent mode before the start of your meeting.

Always bring several calling cards with you

Office workers should always carry several calling cards with them, especially when meeting new people for networking or business purposes. Get a leather or magnetic card holder to store your cards to keep them pristine.

Check your attire

Dressing appropriately for the office is a must for any employee. As previously reported by Jobs & Hire, the way you dress for the workplace says a lot about you, and you never want to give your boss and co-workers the wrong impression with what you wear. Check your office dress code and dress accordingly.

Re-read your email before sending it

Check your email for any grammar or spelling mistakes, and don’t use acronyms or unprofessional terms when communicating with your co-workers. And whatever you do, don’t use emojis in your business emails.
