If you have a job that takes you out and about for the whole day do you include your commute to and from work within your working hours?
If you work from say 9-5. Do you leave home at 9 and get home for 5?
Or, if the work is local, get to your first job for 9 and then expect to finish for 5 before driving home.
The work is never more than 20/30 mins away, sometimes less.
