You are technically correct, but I would posit “secretly holding two full time, demanding, salaried jobs” is an extremely strong predictor for failing to perform sufficiently at either. Given that, it’s a simple matter of weighing those odds against the costs involved in proving it. One common argument is if you can’t tell their performance is impacted, they must actually be performing adequately. Except, in a different context, we will happily explain how our own performance can’t be measured by number of lines changed or bugs fixed.
