Yes, this is what I never get about incentives like that: why on earth would you want to incentivise your employees to come to work sick? A constantly sneezing worker will be unprofessional, prone to making errors, much less productive and endanger his/her co-workers. Now, granted, this is Amazon so no client will see those warehouse employees and I guess their processes are so airtight that one employee making mistakes won't have such a big impact (four-eyes principles or whatever). But it still seems pretty inefficient to me. In Switzerland, some companies have insurance that covers sick days for employees - if your employee is sick, the insurance company will pay the wage during that time. This is mainly meant to cover longer sicknesses in smaller companies, who otherwise might get into real financial issues, but it also has the (in my opinion) desirable side-effect that a company is actually better off sending you home than having you at your desk as a half-productive zombie.
