Results showed a third of people are consumed by thoughts of work from the minute they wake up, while one in four said they only stop thinking about work last thing at night.
The inability to switch off is having repercussions with over half the study (51%) saying their work life has impacted their personal relationships and in some cases led to poor health (52%).

This was most commonly shown through more arguments with their partner (52%), a decline in the quality of their diet (47%), while nearly a third (27%) spent less time playing with their children.
