Elephant in the room the "sick days"!
I know for a fact that my company, now mostly WFH, has seen absentism drop like crazy and sick days are almost non-existent in our dept now. Even in my own team of 8, I think we've had a total of 3 sick days in 2 years and prior to that eveyrone had at least 2-3 days a year to make that fake croaky phone call so they could sit at home all day watching Oprah and playing Call of Duty!
