I’ve read about a-hole control-freak bosses who ‘require’ doctor’s notes if you’re sick. It would be really cool if you could request a medical professional’s note through a website. They could then sign it digitally with a click or two. Then you send HR or your boss the link to the note. Only the date(s) are blurred out. Your boss/HR would unlock that date with a payment or by sending a note to the site, on company letterhead, requesting access to the date. Due to HIPPA concerns or something.
