The sore throat starts on Monday. Tuesday adds a headache and congestion. On Wednesday, you ask to leave work after almost hacking up your lungs onto a client, but your boss is being uptight. So you tough it out and go home exhausted, skipping dinner and falling into bed. You feel a little better on Thursday, so off to work you go. But by Thursday night, you feel like the victim of a hit-and-run. So you call the doctor early Friday. She can squeeze you in that afternoon. You ask your boss if you can leave early for a doctor’s appointment. He gives you a disapproving look like you’re a naughty 4-year-old, informing you that he’ll need to see a doctor’s note.
