I need to leave the country for the summer, hopefully for four months, but I can't afford to lose my job as I need it to pay for college next year. I have been denied the time off by HR and now am looking into the avenue of getting a med. cert for the summer (for mental health related reasons). Can anybody tell me what period of time a doctor's note can cover? Or does anybody have any ideas or advice on how else I can get the time off without losing my job?? Thanks
