yeah there are backstabbers out there i have just experienced it first hand,
I saw it coming when a guy I had never met before started the conversation with I dont like you . he was a supervisor and had never met me before . I still dont know what his problem is but he is making a lot of problems for me. He has lost my timesheets deliberately twice, told lies about me to senoior managment to cover up his own mistakes , other supervisors and techs have warned me that he is doing this stuff but we dont know why.
i have tried to have it out with him face to face , but he creeps away every time ,
