hi, as an employer if you started talking about rights your job would be on the line, im not stupid enough to tell you this but i would be looking to out you, this is harsh but im just being honest, i would never stop anyone going to the docs and i always pay but!, as said i would expect you to try and make the appointment at the most convieniant time to suit the job ie early or late or lunchtime, what i dont like is someome telling me they have a dentist appointment at 11am i am not daft and when i book appointments i make sure they are at the right times, i would also appreciate the person offering to make the time up although i wouldnt make them, on saying that my firm is small, things may be different in big companies
