Part-time employment

This is an example of what makes part-time jobs worth doing: You earn in a full-time job using up 60 hours a week including commuting, and costing in travel and food expenses. You're actually making . Get a couple of part-time jobs making each and doing 40 hours, and you're ahead by if you don't have the overheads. You're also not dependent on just that one job. Make sense?
