What we measure
We use Lost Time Injury Frequency Rates (LTIFR) to track the number of employee accidents per 100,000 hours worked, that result in a staff member needing to take >1 day off work.
Why we measure it
Safety is one of our core values, we keep each other safe. The Work Safe Home Safe framework focuses on managing our safety challenges through key pillars including leadership and culture, safe assets and workplaces, safe ways of working, safe third party delivery partners, and health and wellbeing.
