Sometimes get to wondering where your wandering workers spend their hours while away from the office? Now you can find out - for $15 a month.

Building on its already popular mapping service, Google has taken the wraps off a tracking service that allows a business to monitor where employees go and how long they spend there.

Aimed squarely at businesses such as courier companies and service firms, the tool monitors the location of employees' Android handsets and overlays this information on a Google map. Pretty cool stuff for $15 per employee per month.

Dubbed Google Coordinate, the service can issue jobs to workers based on their location. They then have the option to accept or reject and even chat with HQ via the app.

While there are already a range of services on the market that perform these kind of tasks, Google believes the potential customer base is going to grow rapidly - and it's keen to have a slice.

Employees can disable the tracking app outside working hours to avoid electronic prying into their private lives, or set it up so it automatically turns on and off at pre-determined times of the day.

Can you see a role for a tracking service in your business? Or is it all just a little bit too Big Brother?
