Well it depends.
It depends on what 'cost' you're talking about do you mean to the individual, to the business or to the UK economy as a whole?
Just in case you're really not sure here's all three!
The individual cost of workplace stress can be catastrophic.
I'm talking - developing severe and horrific physical and mental health complications which may leave the individual out of action for weeks, months and even years.
Most people are aware of the mental health costs (and if you're not it's usually depression & anxiety, although it has been linked to things like bipolar disorder, schizophrenia...).
But, more recently research into physical illnesses has shown clear causal links between stress and things like cancer, heart disease and diabetes.
More often than not, because our brains and bodies are linked you'll usually have a combination of both - sorry!
The ability to carry out 'higher order cognitive functions' (thinking, processing and recalling information) is significantly impaired.
Currently productivity levels in the UK are shocking (and if you didn't know this it really, really is).
One study last year showed that if we replaced all our workers with German's they'd come in do the same amount of work while taking half a day off on Thursday and chilling at home all day Friday.
Workplace stress, depression, and anxiety is estimated to cost the UK economy around 6.4 billion pounds each year, and if we only added 1% to our productivity levels then within a decade there would be an extra £250 billion knocking around in the UK.
That's a phenomenal amount of money.
Imagine what we could do with that money.
The NHS 'black hole' is only 22 billion.
We'd be able to pay for that with loads to invest in infrastructure, education, social services, the police force...
Reducing workplace stress is by far the quickest and easiest way to get the country back on track.
