Those who have worked in an office have their stories about an annoying coworker. It could be about stolen lunches from the fridge, microwaving the most pungent fish dish known to man, or even clipping their fingernails at their desk. 

We’re taking things up a notch in this list by showing actual photos of awful workmate behavior. These images could make you question how supposedly full-grown adults could act like undeveloped human beings. 

If you’ve experienced these sorts of actions firsthand, you may feel some secondhand annoyance as you scroll through.

    One difficult thing about having an annoying coworker is that you will have to deal with them every day you’re at work. It’s likely why every action, even if it doesn’t directly concern you, can be vexing. 

    But according to licensed psychotherapist Dr. Maria Baratta, it could also be because they may remind you of a family member who causes you the same aggravation.

    “Perhaps your overbearing supervisor reminds you of your father and just might trigger anger that is disproportionate to the situation at hand,” Dr. Baratta wrote

    “So not only is your coworker annoying, you are doubly triggered by behavior reminiscent of someone annoying or difficult in your family.”

    According to psychologist and relationship expert Dr. Abby Medcalf, there are several types of difficult colleagues. One of them is what she refers to simply as “The Angry Coworker.” 

    While it is self-explanatory, Dr. Medcalf says this person can be so confrontational that they may leave you feeling inadequate, frustrated, and resentful.

    Colleague Destroyed A Painting I Wanted To Buy

    A damaged painting with a large tear across the canvas, an example of awful coworkers' actions.

    I work at a thrift store and we had about 10 paintings coming in all really beautifully done, the frames where also very neat. I fell in love with this one in the photo but someone else had to price it before i could buy it so i ended up waiting until the end of the day to see if they got priced yet. My workday was almost over so i decided to walk to the back to see if the painting was priced yet and lo and behold, 10 painting in the trashcan. And not just in the trash can, my coworker stabbed them with a scissor. She smashed up the frames from the other paintings too and did the same to the art. I asked her why she did that and she just said "they never sell in store" while ive seen plenty of painting leaving the store for good prices and if we cant sell them we always end up using them for our own creative projects.

    I of course went to my supervisor and he said he would have a word with her but i was absolutely furious, i cant stop looking at the painting and how beautiful it was. I also feel bad for the person/artist that donated the paintings thinking they would get a loving new home.

    It’s acceptable for employees to destroy merchandise now? Since when? Where? Not sure if I buy this one, especially with the boss being so non-chalant about it. Unless boss and other employee both have it out for OP, because even if the store doesn’t want to sell them, why destroy perfectly good art?!

    Dr. Medcalf says the Angry Coworker may struggle with low self-esteem and lash out to assert dominance or to feel superior. And one of her most important tips in handling this type of person is to hold your boundaries. 

    “Be clear about what specific responses you’ll have if they continue to act this way with you in this conversation, and then follow through,” Dr. Medcalf wrote.

    Then, there’s the “Identified Patient (IP) Coworker.” According to Dr. Medcalf, this person has either been identified for treatment or as the problem in their family. 

    As a result, they also become a headache to deal with in the workplace because of their baggage, whether it’s an underlying mental health issue, unresolved grief, or problems with another person in their life.

    When dealing with an IP Coworker, Dr. Medcalf’s most important tip is not to feed the person’s story. She also urges shifting the conversation to something along the lines of, “I hear you, and how are we going to deal with this now?” 

    The goal is to stay in the here and now of the underlying issue, not in the unrelated problems they bring to work.
