I'm going to call out of work with acute bronchitis even though we're short staffed
Do you have a doctor order for that illness?
I do what I want to do, don't you understand?
People who have acute bronchitis generally have very few problems with their recovery as long as they get the treatment they need. You can expect to stay home from work for a few days while you are recovering.
I'm going to call in sick because I want to go to a wedding. I don't need to find someone to take my shift, what a waste of time.
Why lie about it? You can always take your vacation time. You have that right and just let someone do your work if they need the extra income.
