If you have a background in IT, Engineering or Telecommunications,
it is possible to work from home in Technical Support.
This can be a demanding area to work in, as you need
to know the technical details of what you're dealing
with, and you also need to be able to communicate well
with customers experiencing a problem.
First and second level support can be done from home,
and requires knowledge specific to the business you
are working for, and equipment similar to a standard
customer service job. i.e. a dedicated phone line and
quiet area to work from.
As with some of the other work from home options, there
are more technical support jobs working from home in
the US than in Australia. I have found forums with people
telling you how they work from home in technical support,
but I have found very few jobs advertised.
I will do some more research and keep you posted.
If anyone knows of jobs in this area, please let me
