I switched from a professional role to working in my family business which is a niche industry. My Dad & I decided I needed experience outside the family business so when he heard from someone near me they needed staff I interviewed and got a job local to me in the industry.
There was a real culture of bullying led from the top loads of staff started and left quickly. There were two ring leaders who were horrible to everyone including me. Anyway I decided to get an industry qualification which involves an exam and a mock interaction with a customer. As soon as they found out about this they ensured I was always working in the quiet office and for about 3 months didn't actually get to interact with customers they took every job. They would also tell me how hard the exam and mock customer exam was and how one of them failed first time.
So took the exam and passed which was great to announce to them, what was even better was when I got a phone call whilst they were in the office asking why I had put down not to attend the award ceremony, I was then asked to please attend as i'd received the top marks in the country 
There was a photo of me in all the industry magazines it was great.
They were still horrible and continued to be nasty including clearing my desk including kids photos and chucking them all in a box rearranging the office so that I had to work in reception. I eventually quit and went and worked for my family.
