My dad is dying within a week according to his doctor, I'm crying while working everyday. Today emailed my boss and said I'm mentally distressed and want to spend time with him and family before he passes. He always responds within a minute, he has not responded. He always says we need to let him know weeks before taking time off, but I could not plan my dad's terminal cancer, or know how fast he would decline. Just angry and upset at the same time. I want to take disability so fuck him up, I'm afraid after that he might fire me. I'm on H1B visa.
