Measures of working days lost: Definitions and formulae
For working days lost, the LFS gives estimates and rates of the total number of days off work due to work-related illness and/or workplace injury where:
- Working days lost are expressed as full-day equivalent (FDE) days to allow for variation in daily hours worked and includes days lost due to all non-fatal injuries (excluding injuries caused by road accidents) and all work-related illness (new and long standing cases).
- Working days lost due to work-related illness is a measure of the total time lost due to all episodes of the illness over the 12 month reference period whereas working days lost due to workplace injury is a measure of the elapsed time between injury and returning to work and does not include any subsequent time taken off work;
- Rates presented are in the form of average annual working days lost (full-day equivalent) per case of work-related illness or workplace injury and average annual working days lost (full-day equivalent) per full-time equivalent worker.
Theformulae used to calculate the various measures of working days lost are given by:
| Estimated annual full-day equivalent working days lost | = | The estimated number of full-day equivalent working days lost due to workplace injury (excluding injuries caused by road accidents) and/or work-related illness for people employed in the 12 month reference period Note:
|
| Estimated average annual FDE working days lost per case | = |
Estimated annual FDE working days lost Estimated number of people with a work-related injury or illness, in the 12 month period, who worked in the same period |
| Estimated average annual FDE working days lost per full-time equivalent (FTE) worker | = |
Estimated annual FDE working days lost Estimated number of FTE workers in 12 month reference period Note:
|
The above formulae are refined slightly for days lost estimates by employment-related variables (such as occupation or industry) to account for the fact that the LFS only collects employment-related information about the current or most recent job in the last 8 years.
