I've been working for this company for 2 and a half years, and i haven't used vacation once.
I fell down the stairs a month ago, and hair fractured my lower right rib, so I spent 3 days in the hospital getting tests done.
I returned to work with a doctors note for the 3 days of my absence, and requested 1 day off for September 1st.
It was denied because my HR manager said I just took time off.
