<human>: Condense the text into a few key points

as someone who is currently trying to keep my sanity, fight the desire to call out and generally have a, "normal day at the office," i really need reddit to come through for me here.. i currently work doing mid-level supervisory stuff in my office and work with the same people day in and day out.. gossip flies around that place like herpes, and generally when someone that is well-liked by upper-management decides they don't like a particular person anymore, soon nobody else does either.

all that being said, it's my turn--people don't send me important emails, ignore and outright refuse to communicate things to me, accuse me of things like favoritism and loudly proclaim their apparent aversion to me. all attempts i've made to speak with my immediate supervisor was met with apathy at best, and retaliation from the people i've made complaints about at worst.

i've been dealing with this sort of thing on and off for the duration of my 2 years at this place, and after overhearing a conversation in which a higher-ranking member of staff called me, "a stupid, childish idiot that he wasn't going to speak to anymore," i couldn't help but be brought to tears.
<bot>: When going to internal management fails only results in retaliation, what do you do to properly report, and stop workplace hostility and bullying?
