My daughter has been forced to listen to a man in the office opposite hers using the most vile language . He works for a different company and she's often in her office alone. She can hear him through two doors ! This morning he was on the phone telling someone on the other end that "she wasn't available for sex as she was in a period. " He then asked for recommendations for prostitutes in the area he was off to for business .... all accompanied by mysoginistic and vile language. Sounds a great guy doesn't he ? My daughter has said she intends to take his photograph and post it on social media along with his comments. I've questioned the wisdom of this and suggested instead that she contacts his firm and tells them what she has to put up with on a daily basis. What do people think ? Any suggestions as to how best to deal with this ?
