Extreme heat and wage supplementation: using the adverse weather ground

TOPIC
What matters is not the recorded figure alone, but perceived temperature in relation to the task.

High temperatures fall among the weather events justifying recourse to wage supplementation for suspension or reduction of activity, where they make work unsafe or technically impossible. What counts is not so much the absolute temperature reading as the perceived temperature, assessed in relation to the task, the exposure and the actual conditions of the site or the land.

Relying on this ground requires a timely application, a precise description of the operations suspended and supporting weather data for the place and days concerned. Weeks claimed on this ground also follow their own counting rules compared with other ordinary schemes, and should be coordinated with the heat stress risk assessment.

IN PRACTICE
Keep, for each day, the local weather bulletins and a named list of the workers and operations suspended: this is the documentation that will support the application if further evidence is requested.
