As a Millennial or a Gen Z’er, you’ve probably encountered a lot of acronyms in your short life. OMG, LOL, WTF, ROFL, TBD, ILY, NSFW, BRB, BTW, JK, LMAO, ASAP, TTYL, TMI, SOL, NP, IRL, TBA, BFF, FYI and probably way more that I don’t even know about yet.

But what happens when you’re in the office for your first internship or professional entry level job, and you get an email from your boss with acronyms like WOMBAT in it??

The business world loves acronyms almost as much as you do, so take a look at a few of the most common acronyms you will likely encounter in your career:

2. EOM

This one can be used in one of two primary ways:

EOM: End of Month

EOM: End of message. If you’re sending a very short email, you might end with EOM to signal that there isn’t anything else you meant to include in the email. You can also put it at the end of the Subject Line if that says it all and there is no body to the email.

Example: “Subject Line: Please Empty Dishwasher EOM”


OOO/OOF: Out of Office. When you’re going on vacation or will otherwise not be checking your email regularly, you can set up an automated reply to let others know where to direct their questions while you’re gone.
