I thought the mask was mainly for other people? I remember it being hotly debated but last I remember seeing anything I think that was what was said

Yeah, it catches (lots of but not all) aerosolized saliva from the wearer’s mouth, which means a carrier is putting less viruses into the air. It’s far less effective the other way: stopping viruses in the air getting into your lungs, but it’s slightly better than nothing.
So, if someone feels sick but cannot miss work, this allows them to lower the risk they pose to others near them.
