What do you consider the "mobile" worker?

Hey you Savs,

I work for a company who's unique selling prop. is aimed towards the mobile workforce. A problem we are running into is that people have different definitions of mobile workers. For instance, we help workers who are completely mobile like casino, construction, healthcare, etc. People who do not have a corporate email address. But some people see mobile workers as those who can but choose not to work at a desk. What would you consider a mobile worker?

Thanks!
