No Work Etiquette

I am pissed because people at my job has no regard about work etiquette. They always call in sick almost every week. They have no concern about the people who's in the office working alone. It's been happening all the time. I hate to deal with them. The company is very lenient too about sick time and vacation time. Somehow that I myself could get benefit. But people at my job are just using it too much. For me I always plan ahead my time on when to use it and when it's really needed. I guess they just don't work like I do.
