Is is legal for my employer to deny me time off for medical or dental appointments? Am I required by law to gain approval for these appointments prior?? I put off an infected tooth which needed a root canal because my supervisor told me we were too short-handed at work. I work Monday thru Friday 8:30 to 5:15 with a 45 min. lunch. I was told mondays and fridays were out for appointments due to short staffing and thursdays were out due to shipment..( I work in a local Bank). That leaves tuesday and wednesday and my OB/GYN does NOT work Wednesdays. What am I supposed to do for my health sake?
