My name isXXXXX and I'm happy to help with your question today. I need to ask you some preliminary questions to be able to help you.
What is your objection to this?
Sorry - - I don't understand what you mean by 'hell'.
Do you still need help?
Sorry, spelling mistake. I have a birth make on my scalp line which i keep covered up with a cap for most of the time. I do have a stigma about it, and i would prefer not to have a photograph of my face displayed on a notice board for others to see. I know it might seem trivial, but to me it is a real issue. Can i say no to this request?
Yes you can. Your employer has a duty to avoid any form of discrimination/harassment/victimisation in the work place. If you feel that displaying this photo will result in negative behaviour from other employees and result in the behaviour I've just mentioned you can ask your employer not to display the photo. If they refuse your request your next step would be to lodge a formal grievance although once you've aired your concern they will hopefully discuss a suitable compromise.
