There you are, head down in a report, a spreadsheet, or some other urgent bit of business. There’s a knock, and your mind returns to your desk from miles away. Someone says they have a problem and can they talk it over with you please? An interruption. What are you going to say?
Your work is high-value, it takes real concentration, and you need to keep your focus to get it done right. On the other hand, if you send them away, you may be telling them that you do not value them and what they do.
Of course my own work seems urgent, but I know I’ll get it done one way or another. My colleague on the other hand is important, because it is essential for the longer term that they feel valued. I could easily – and quickly – damage a relationship I have taken a long time to build. I know they would not interrupt me when I’m busy unless they felt it was important. It is really important to give them something to show that I’m taking them seriously.
Even if I decide I can only spare 5 minutes now, I’ll always offer that as a first step, at least to give them things to be thinking about until I can pay full attention. If I give them proper respect, value them, take their problems seriously, I find that they respect me back – and interruption is rare unless it really is necessary.
So if you really can’t deal with the interruption fully there and then, at least find some compromise. It will pay you back in the long run.
