This is an excellent must read article by the New Statesman. The article suggests that if you can’t handle the stress of working in a low-pay world, it is always and only your fault. However, it argues that it’s time that presumption changed.
Whilst I can recognize descriptions of big corporate bullying and systemic management by fear, I suggest that this is only part of the story. In my long career in both the private and public sector , it was in the public sector that I found more evidence of mental health issues.
My personal theory is that mental health issues are more prevalent in bureaucratic organizations with broken processes, like the public sector and large banks?
