In theory: sure it sounds great. Being a former Comcast employee prior to the TWC merge, I highly doubt it will happen. There will always be contract work; its simply cheaper than having all the work in-house.

The trick is to hire and use internal employees for a steady state budgeted workload and then hire contractors for expansion projects and for those times when problems occur(like hurricane season in some locales and ice storms in other locales).
