Every minute I’m forced to work while tired is violence against my body. I do not have time in my day to continue working for such trite reasons as “my shift isn’t over yet.” My body’s shift is over when it is tired. I am not here to fall asleep at my desk while I have more important things to do, like sleep in my bed.. I am here to earn a living, and I cannot live if I need to sleep. No I will not go to bed earlier. I will not plan my sleep around a job I do not like. You will schedule my work around when I sleep. And if I sleep all day, then you are not entitled to my labor. I am not running a charity and you cannot rent my body for all hours of the day. My work is making you rich while keeping me poor and tired, so you will thank your lucky stars I came into work at all.
Edit: I guess I should make it clear that this is a joke. I think most people got it but just in case.
