That doesn't make much sense--payroll tax is roughly 15% either way, so with employees you just pay them 7.5% less than a contractor for the same benefit.
The real reason for contracting is that the paperwork is much simpler. You don't need an HR department. And the guy gets automatically laid off after a few months without the incident reflecting on either you or him, so there's less risk.
There's another side to it where you can hire a "contractor" on an n-month term, but instead of paying the contractor directly you go through a middleman who hires the contractor as an employee and provides (shitty) benefits and takes care of taxes.
