I have been at my job for almost 8 years and I work in a large office. I definitely struggle at times, especially in the winter when sickness is going around. I also will not use the public restrooms for fear that someone will have to v* while I am in there. Thankfully there are 2 single stall private restrooms (they are actually only for men because there is so many more woman that work there) but I still use it when I have to use the restroom. About 2 years ago I got my own office so I think that helps that I can close out the germs from the rest of the employees. I still go thru a bottle of hand sanatizer every 2-3 weeks and I spray all the surfaces with Lysol every week. I haven't caught any bugs yet (knock on wood) so I think my rituals help.
