The Brosix blog posted an article on IM etiquette on Jan. 23, 2009, but I’m here to continue the discussion on IM etiquette and how it impacts the way people see you in the workplace.
Even though many use IM and chat lingo, such as ‘OMG’, ‘hehe’, or ‘lmao’; it is not usually appropriate for the workplace. Make sure you present yourself as a educated and eloquent employee and co-worker, even though you are using online communication. Make sure your words are spelled correctly and you are using proper grammar. Smileys and abbreviations may be ok for more casual conversations, but in IMs where business is involved, make sure you keep it professional.
Also remember, that everything you say in an IM conversation can be recorded, monitored, or kept, just like an email or voice message. Even if your employer doesn’t monitor IM conversations, other employees can keep their own logs of archived chat conversations. These can be used for malicious reasons, so make sure not to gossip over IM and to keep confidential information out of the conversation.
Proper IM etiquette can usually be achieved by simply remembering the ‘golden rule’- treat others how you want to be treated. Treat others with respect and professionalism over IM, and you will receive the same.
