Some people always have something to say. Regardless of the subject matter or their personal involvement, they feel the need to chime in at every opportunity. Although this may simply be someone’s personality, others may see it as a deliberate strategy to get noticed and have an impact in the office.
Unfortunately, that strategy can often have the opposite effect. Speaking up at every possible opportunity can actually diminish the perceived value of one’s input. A better strategy could be to actually limit input to situations when one can truly provide genuine value.
