Well, I disagree with your assessment that by taking my sick days I am hurting another employee. It's actually you, as the employer, who offered me 10 days of sick leave, and who knowingly understaffed your workplace assuming that I wouldn't use that time off, who is hurting your employees. Don't rationalize it by putting the responsibility on me. You're the one who told me I was allowed to do it. If you don't want to offer 10 days of paid sick leave then don't offer it, but don't punish me for using it, and don't try to guilt me out of using it by pretending that I'm the one creating the situation. It's your job to staff your workplace appropriately.
