Much of modern work involves being joined at the hip to some form of technological device. But don't forget you're a human being - we love breaks. Here's how to balance your humanity with technology.

After working for three hours without a break, Helen glances at the clock.

'Four o'clock. I didn't know it was so late. I need to stretch my legs.' On her way to the staff room she passes Louise's desk.

'Hi, Louise. How’s it going?'

'Fine, but I've just got so much to do.'

'Me too. I worked late every night last week on a report and I still haven’t finished it. But last night I went to see that new Tom Cruise film. I do quite fancy him blah, blah, blah...' On and on she goes, while Louise thinks of all the work she’s got to do.

Is Helen totally oblivious, with skin as thick as elephant hide? Why didn't she get the message and leave when Louise said she was swamped? Because Helen needs human contact after working on her computer for so long.

John Naisbitt, author of Megatrends believes that the more high-tech activities, such as working alone at a computer, we undertake, the more we need to balance them out with human interaction. The length of time one can work at a computer before needing contact with other people varies widely, depending on your personality and circumstances. It could be just an hour, or a whole day or more at other times. The need to find the balance will only increase as technology continues to affect our working lives. By understanding the ebb and flow of your working patterns, you can get your work done and keep up with your colleagues' film reviews:

1. Be aware of when you need to take a break. Neck ache, eyestrain, headaches or a sore backside are symptoms that can trigger the need to move around and often, to talk to someone.

2. Keep a note of your need to take a break for a few weeks to see how long you can go without human interaction. Then, when you know you'll be working on the computer all day, you can plan to take breaks with friends or colleagues. Set a time limit for your breaks, and stick to them. Regular breaks are very important when working on a computer for several hours a day. The Health and Safety Executive recommends frequent breaks before fatigue sets in.

3. Be honest and assertive with chronic interrupters. Don't expect them to mind-read, or pick up on the subtle body language messages you try to use to tell them to bugger off. They are probably not aware that they are stopping you from doing something important and would rather you said something than let them carry on chatting.

4. Be understanding – colleagues who interrupt may also need to talk to someone. This will help you have more patience with the chronic interrupters, but you should still let them know you’ve got work to do. Don't allow your work to be sidelined. Be diplomatic: try fixing up a mutually convenient time for a tea break.
