Workplace etiquette – what most bothers work colleagues?
Published Apr 28, 2026
A recent study of 2,000 UK employees has identified the habits that annoy co-workers the most!
The research conducted by Essential Workwear found that 10% of workers admit to regularly leaving dirty cups and dishes lying around and a third of workers dislike colleagues that do not tidy up after themselves.
22% of workers get annoyed by colleagues that microwave smelly food at lunchtimes, exacerbating the risk of arguments in communal break out areas!
The research also identified the most inappropriate behaviours of co-workers. The top 5 inappropriate behaviours are:
Flirting with colleagues
Discussing a dislike of a colleague
Scrolling social media
Taking smoking breaks
Putting on makeup or doing their hair at work
22% of UK workers say they find it annoying when a colleague skips a tea round!
How should you deal with annoying office behaviours?
Do not let it build up as you risk letting out your frustrations through an emotional reaction at a later point about something relatively minor.
Have a gentle conversation that focuses on your productivity and not the personality of the co-worker. Instead of telling someone they are “being annoying” try explaining that you are finding it difficult to focus on a complex task. Perhaps ask if your colleague could wear headphones for a while. Such an approach helps avoid direct confrontation.
If your issue relates to the laziness of a co-worker then raise it with your manager. Focus on the impact the behaviour has on you and your productivity. Explain how your co-workers delays or poor-quality output affect your ability to do your job well. Taking this approach focuses on the practical success of the organisation rather than the character of your co-worker. This approach is more likely to achieve the change you are wanting.
If you are feeling social rejection for being omitted from a tea round then that is a natural reaction because your brain processes social exclusion in the same area that it processes physical pain. So don’t be afraid to express how being excluded by co-workers makes you feel.
