Why you gotta be so rude? How to spot these clueless co-workers in your office

Here are five of the most common toxic colleagues The Flake: factor in their anticipated laziness when you're given a project with a lazy co-worker The Betrayer: they'll throw you under the bus the second a project goes wrong, so protect your ideas by sending a memo of your thoughts The Full-time Downer: spend as little time with them as possible The Office Gossip: keep your personal details close and limit this co-worker's access to your social media posts The Narcissist: keep your expectations of what t

Rudeness is running rampant in the office these days.

While loud talkers and food stealers used to be the main culprits — and they still make the cut — these days rudeness is taking on a distinctly 21st-century vibe.

Did you hear about the new trend of quitting via text? Or about ghosting, done by new hires who, having apparently found a better gig before their start date, don't even bother to show up for the job? No word, no notice, nada, nothing.

Not even a text.

Whether it is a toxic political culture that seems to not just tolerate but celebrate rudeness, or a generation perhaps not taught a lot of manners, it's difficult to deny that we are in a regrettable era of increased rudeness that is spilling over into the office.

Who are the worst workplace culprits?

The phone abuser: Do you have co-workers whose necks must hurt from the all of time they spend trying to steal glances at their phone during a meeting? Or worse, the ones who text during the meeting? Or worst, she who texts during a conversation.

Loudmouth: You know loudmouth, right? Loudmouth doesn't know from inside voices. Loudmouth apparently thinks you are really interested in his private phone calls. Loudmouth cares not if he interferes with your concentration.

Food stealer: You know who you are food stealer and we want our lunches back.

Scene stealer: Not to be outdone, scene stealer thinks nothing of taking credit for someone else's work. The only thing worse than a scene-stealing co-worker is a scene-stealing boss.

The interrupter: The Interrupter loves the sound of his own voice. He thinks every idea he has is so good, so important, that it necessitates that he replace your thought with his.

Headphone: Hey, don't bother me, can't you see I have my headphones on?

Ms. Double Pneumonia: Double pneumonia goes like this:

You: "I've been so sick lately. In fact, my doc thinks I have pneumonia."

Co-worker: "You have pneumonia? Wow, sorry to hear that, but did you know that last month I had double pneumonia?!"

It's rampant, right? You went to Hawaii? Well, I guess what? I went to Bali! You had to work late last night? Too bad. I had to work all weekend!

Clueless: Clueless doesn't realize that he put on too much cologne. Or that she needs to wear deodorant. Or that you are having a bad day.

The slob: Apparently the slob thinks that there is a maid service that will clean up after him, or wash her dishes, or throw out his rotten food, or wipe up after her spilled coffee.

Tardy Tom: Tom was an old co-worker of mine who was always late and thought nothing of holding up Every. Single. Meeting. That is, of course, until he was canned.

And let's just say, it wasn't by text.
