An ANU longitudinal study tracking 7,000 Australian workers over seven years found that working in a poorly designed, high-strain job is now worse for mental health than being unemployed.
Employment is not the goal. Good work is the goal.
Her warning about AI was precise: used carelessly, it creates an infinite workday – employees trapped in loops of automated execution, never quite finished, never quite in control.
The right question is not 'how do we make people more productive? It is: what work should humans no longer be carrying in the first place?
Kat distilled the conditions for workplace mental health into a formula that I loved for it's simplicity and power:
Love + [Load / Latitude] x Leadership
Love: People do not just want manageable work. They want meaningful, motivating work. As the saying goes: If you want people to do a good job, give them a good job to do.
Load over Latitude: High workload is not what breaks people. What causes psychological injury is heavy load paired with low latitude.
No autonomy, no control. As Kat put it: "Humans don't break from hard work. They break down from helplessness."
Professor Sir Michael Marmot's research at UCL confirms it: the worst health outcomes belong not to those with the most pressure, but to those with the least control.
Leadership: Leaders are workplace designers. Our behaviour amplifies everything in the system.
Getting this right requires both clarity of expectations and genuine care – and the right balance looks different for every person you lead.
