the answer is no. Why not? It?s likely that the not-so-good employee is better at 9 a.m. after a full night of sleep than the good employee is at 2 a.m. after a -hour workday. So you want to give at least a few tasks to your worse guy. The same principle applies in your household. Yes

you (or your spouse) might be better at everything. But anyone doing the laundry at 4 a.m. is likely to put the red towels in with the white T-shirts. Some task splitting is a good idea. How much depends on how fast people?s skills decay.
