I️ have a coworker, whom I️ share an office space with, that has horrible phone etiquette and just about practically yells at all our patients I️ dk how to tell her to quiet down I️ mentioned it once jokingly and she just didn’t get the hint I️ honestly don’t know how to tell her and with these mood swings some days I feel like I’m going to snap 🙄
