In some tasks or roles, it makes more sense to employ independent contractors rather than full-time salaried staff. Sure the hourly cost may be higher but consider…
You pay salaried staff for 52 weeks work BUT that includes 4 weeks holiday, 2 weeks statutory holidays and often 1 week sick/personal leave ie you lose 7 weeks of actual work ie they work 45 weeks. Then if someone works at an 80% productivity when they are producing “billable hours” (and 80% is recognised as good) 45 weeks *80% = 36 weeks.
So as an employer you pay for 52 weeks work BUT likely received 36 weeks of actual productive or billable hours. That’s only a 69% productivity rate!
Suddenly independent contractors who can be “spooled up” or “spooled down” as required start to look very cost effective!
