The worst place I've worked in 45 years
The problem with GCC is the management culture of fear, humiliation and degradation. I worked there for 7 months and received no useful training or line management support. The colleagues I had were lovely, but depressed and felt used and abused, as I did.
GCC need to realise that the reason so many people leave is not low pay, it's being bullied and deskilked by sub standard management . The rot is endemic and comes from the top down.
Treat people with respect, fairness and kindness and they'll be loyal. Abuse, humiliate and degrade them and people will have nothing good to say. Rightly so.
