Who really is the mobile worker? I'm asking this because if you want to control risk around mobile work, you have to know what mobility adds to the work and how this fits with decisions about the time and place of work. A bus driver, a mobile hairdresser and a consultant are not all mobile in the same way. The mobile bits of work are not often not what they seem. Consider Fergus, the National Park fee collector who I wrote about recently in my blog.
