According to a new Willis Towers Watson survey, over the next three years, work automation will surge through a combination of artificial intelligence and robots—which will drastically change not just the workforce but also HR responsibilities.

The survey finds that very few U.S. companies and their HR departments are prepared for how work automation will change their businesses, and moving foward, companies will be less reliant on full-time employees and more reliant on contingent talent.

However, responses reveal that very few companies and HR functions are fully prepared to address the organizational change requirements engendered by a greater dependence on contingent workers and smaller reliance on full-timers.
