My first job out of uni.
I was hired by a charity I'd been volunteering with and made redundant six months later at the end of the contract
The whole six months was a dreadful experience.
Years later I finally realised that the only reason they had EVER hired me is because they wanted me to fail and thereby renegotiate the contract terms with the external funder.
When it became apparent I was good at it and received a lot of external praise the environment just became more and more hostile. The original contract had been failing because my predecessor was a lazy fucking arsehole hated by his contact book.
They offered me no support, sabotaged me and blamed me for being unable to fulfil a practical aspect of the job role that I declared at both application and interview I was unable to fulfill.
Any small criticism became blown into a huge failing, and my supervisions were always one long "you're shit" no praise my manager made me cry twice and was jealous of positive attention I received
With my full support the contract was renegotiated as I had identified that the need was misplaced, the funder agreed and wanted me to stay in post under the new contract.
The charity refused and said I would have to reapply for my job, I knew immediately that if I were to reapply I wouldn't get the job, and I wasn't prepared to be humiliated and refused to apply and told the funder exactly why. They were willing to move the contract to keep me but the charity had the monopoly on a certain provision in the local area and so they couldn't get permission.
The bittersweet element was that with in a year of me being fired under the guise of being made redundant (and they sent a letter to my clients that read like I'd been fired) ; two separate people who knew two separate former colleagues approached me socially and said they'd resigned and that both had cited the way I was treated there the entire duration of my employment in their resignation letters as things that had prompted them to leave.
Absolute bunch of bastards with the exception of the two who resigned.
