Is the personnel shortage is because most people can't handle 8 hour shifts, then it's plausible that you'd have more than 4 times as many people that can handle 2 hour shifts

If 1 in 100k can handle 8 hours, and 1 in 10k can handle 2 hours, then the solution is to employ 4 times as many people for 2 hours.
