The work has got screwed up lately. There have been some organisational structural changes (big word right, n so is the impact) that has lead to increased friction between various units mine being one of them. The boss is supportive but his boss is not wtf. First thought in the mind let me find another avenue n second one let me fight it out. Sounds sexy, trendy and so much youthful. But is it actually possible. Is the work life really like a film, rocket sing salesman of the year. And is it worth fighting for. What u do when best of ur allies become worst of ur enemies? What u do when ppl u trusted the most have chosen to work behind ur backs? Blame them confront them or just plain ignore them. Ignore u cant coz their deed is gonna affect u. blame them is not an option coz u know they have done this to save their arse. Confrontation is a viable option, that will at lease relieve u if not help u.
