Maple-flavoured peasant here - Dr’s Note requirements make way more sense in a functioning healthcare system as a specific way of justifying medical-related leave. If I want to access workplace support for medical emergencies, or long-term leave, I don’t think it’s wild unreasonable that the employer wants to see some measure of proof that it’s legit.

Using it to address general absenteeism as a starting policy for any day off is fucking stupid, but that’s on the employers and not the doctors.
