Today while discussion out workplace network, a co-worker was explaining how he accesses the network through a webmail login. He referred to accessing the network this way as using a back door method. My boss laughed out loud and stated, "well you know how I feel about the back door." This isn't the first time she has made these types of comments in front of me (I'm her direct report). These comments are very uncomfortable for me. Because of a prior complaint by me, our company has hired a "coach" to help her address her workplace tact. Her behavior has not gotten any better.
