Ever noticed that your Slack messages and emails are getting shorter and -sometimes- more difficult to decipher? It seems that the language at work is full of abbreviations, also known as business acronyms.

Even if you’re an expert at acronyms, there is always a new one that you don’t quite know. And if the idea of admitting that you don’t understand something sounds cringeworthy, you’ll want to download the cheatsheet below.

Which abbreviations are appropriate in business and which aren't? ASK YOUR TEACHER

As I was saying, BTW, sometimes your HRM tells you it’s NBD and TYT but TBH they just want that file ASAP by EOB and, you know, ATEOTD, they’re the manager. Does this look to you as if I just bashed my head on the keyboard a few times? You’re not alone.

More official acronyms you’ll see at work

What do I mean by ‘more official’? Well, the acronyms from the previous section were more common among friends’ texting, and they are progressively taking over the business world.
