iTALK INITIATIVE

iTalk was set up to help businesses achieve sustainable success via creating and maintaining mentally healthy, psychologically safe workplaces where people thrive as part of a supportive work community.

Increasingly, businesses are wanting to tackle the problems caused by poor mental health and gain the benefits from investing in positive mental health and psychological safety – better recruitment and retention, attendance levels, performance, productivity, etc.

And key sectors like Construction are increasingly wanting to take steps to tackle the problem of high suicide rates, especially given the fact that Construction workers are 10 times more likely to die by suicide than a physical injury or accident at work.

iTalk works with organisations that want to make a long-term commitment to a mentally healthy, psychologically safe workplace; and be part of the solution for reducing suicide rates.
