You decide that you don't feel quite sick enough to call out of work. You are a receptionist for an office.
It's just taking calls, and scheduling meetings. You get to sit down for most of the day. It's not like it's hard.
Your boss asks if you're feeling alright when you walk in. You say you feel fine. They say you look tired.
They tell you to take it easy for today. Take an extra ten minutes when you go on break.
You think about asking for an extra hour. Or an extra twelve hours.
