CHICAGO—Finding quality labor for a new warehouse has become difficult for many firms, and the task of staffing a facility is likely to get even more challenging in the years ahead. Only about 9% of all retail sales are completed using e-commerce, and that portion is expected to rise precipitously for at least another decade. And even though distribution centers are utilizing more robotics and other high-tech tools, the low unemployment rate means its getting hard to find the right people to run such operations.
