For companies seeking to replicate Uber’s success, it’s important to understand that high attrition rates may not be a feasible long-term strategy—the flood of part-time workers could always dry up. Many drivers, both full and part timers, already strategize to maximize their incomes by switching between multiple platforms that offer different incentives or premiums. Uber, Lyft, and other app-based employers stand to gain from retaining dedicated users, or “power drivers,” who may be willing to work under more strenuous conditions than social or supplementary earners. Platforms should seek to understand their diverse workforces and offer distinct employment promises that speak to their varied motivations and needs.
