Work-related stress, depression and anxiety has rocketed in the last three years.
Between April 2015 and March 2018, an average of 1,370,000 work days a year were lost in the West Midlands to stress, depression and anxiety caused - or made worse - by work.
That is up from 851,000 days a year between 2011 and 2015.
It means the average employee in the West Midlands takes off 0.6 days a year due to work-related mental health conditions.
That is above the national average of 0.5 days.
The data shows that across Great Britain, work-related mental health problems have been rising sharply in recent years.
A average of 13,188,000 days a year are now being lost to stress, depression and anxiety caused or exacerbated by work.
That is up from an average of 10,572,000 days a year between 2011 and 2015.
Workers in Wales are the most likely to take time off because of work-related mental health conditions.
The average employee there loses 0.7 days a year to work-related stress, depression and anxiety.
Workers in London are the least likely to be affected, losing an average of 0.3 days a year.
The data is published as part of an annual statistical report by the Health and Safety Executive, which came out today.
It shows that stress, depression and anxiety accounted for more than a third of the 30.7 million days a year being lost to work-related illness and injury.
Those are costing the economy an estimated £15 billion a year.
