Dude that convinced me to come to company became the most toxic person ever after I got fed up of his lies and lame attempts to get me to do his job (so he could just get the merits). We don’t work on the same project but closely related. Every time we speak he tries to hurt me by trying to put me down/raising sensitive topics. But he gets rid of the history all the time, so I have nothing to handle to HR or manager. Time to jump the ship? Job is fine otherwise.
