With workplace stress and burnout at record levels, everyone needs to understand the mental health challenges we face at work. But these challenges can be hard to anticipate and manage, whether we're tackling our own sense of overwhelm or trying to help a colleague. That matters, not just for individuals, but for organisational wellbeing too. Poor mental health is miserable for the people affected; it's also bad news for success more widely. That's why we need to work on our Wellbeing Intelligence (WBQ), a first-aid kit of tried and tested tools to help us assess and manage mental wellbeing as individuals, in teams and as part of wider organisational cultures. From self-care and self-assessment to how to help others and the right kinds of policies and support, Wellbeing Intelligence offers a practical guide to better mental wellbeing for everyone.
