Note, my suggestion wouldn't only apply to their requests under their new interpretation....it would apply on all the holidays the CBA specifically addresses
My main point is that the FDX approved medical insurance provider, BC/BS, fully recognizes (and even encourages) the use of their 24/7 Nurse Line when faced with minor illnesses and injuries
Using the Nurse Line should be acceptable --- it's lower cost, and meets their intent that you sought out appropriate health care
I'm sure the Nurse will recommend you see a physician if the condition warrants
