to HR with the probs I am having with a coworker? Shes essentially a self absorbed insecure and manipulative cow ( not very popular with anyone in fact so not just me who feels this) but i am stuck working with her. Tried to be nice. get on with her but shes affecting my job now, lying to and misleading mgr to look good and making my job difficult. Mgr is useless and wants a quiet life so wont address anything. Am afraid it be my word against hers tho and shes a bit on the scary side. am i going to make my work life harder if i tattle?? should i just accept that some people are horrible and get on with it?
