Presenteeism

Presenteeism is when someone goes to work when they are not feeling well, either mentally or physically. If you are feeling sick, but you still come to work, then you are practicing presenteeism. It's important not to do this because when you don't feel good, it is hard to work and you could spread your sickness to other people. If you are feeling a bit unwell, you should stay home and rest so you can get better soon.
