Hey Tia, its really common in the workplace for cliques to form. At the fast food place I worked at there was a really weird vibe. And recently, I did a few shifts at a residential home & I could see straight away the cliques that were set in stone. Its typically the longest serving staff that cliques emerge from.

They create a culture in the working environment which becomes routine. The restaurant I worked at was full of crass, crude humour which was passed off as "banter". People would also freely gossip to their clique & most were so obnoxiously loud. Some of the established staff in a workplace can also appear to be self absorbed. A few girls ive worked with seem to be abrupt in their tone for no reason whatsoever.
