Giving specific benefits often ends up going along with requiring specific proof of need for the benefit. I had classes in college where attendance was part of the grade. Additionally if you had to miss a class due to being sick, you had to produce a doctor's note. The attitude for myself and others was largely fuck that, I'm not going to the doctor for a cold or flu. I'll just come in and infect everyone, hopefully the administration/teacher who introduced such a policy...
