For many, it's the ideal scenario. Home-based work is the ideal way to manage the work-life balance, providing you can handle the distractions of course.
For others it's a way to supplement their income - a couple of hours in the evening perhaps, or a way to tun a hobby into a few extra quid.
On the Zoek job search site, we always have many job opportunities that fit the 'work from home' bill. In fact, if you search for a job title without specifying a Location, you'll always see the home-based jobs at the top of the job search results.
