This is sick.

> workers are not required to provide a doctor’s note until after the third day they stay home with an illness.

There are ways for employers to require on the first day if abuse is suspected. Amazon should stick to established employment practices than to come up with contractual innovations that undermine the spirit of the law. The risk that a worker is becoming sick belongs firmly in the realm of the employer and not of co-workers. Shifting that is abuse of power.
