The Know-it-All. Negative Nancy. Larry Loud-Talker. The Over-Sharer. The workplace is filled with all kinds of personalities, each with their own unique (and sometimes annoying) habits.
While you can’t choose your co-workers you can choose how you handle their annoying behaviour. Your best approach will largely depend upon your circumstances, and the level of annoyance.
For example, if your co-worker’s habit hampers your ability to do your job you’ll need to take care of the problem, even if it means going to your supervisor. However, filing even a "verbal" complaint should always be your last-resort. Meanwhile, you may want to look at your own workplace behaviour which, unknowingly, may be offensive to others.
