I’ve been told that the armies in many countries use sliding scales of work-rest cycles based on temperature and humidity. For example in Canada, above 35°C you may only have half the crew working 30 minutes on 30 minutes off. Meaning you have 50% of the work being done 100% of the time. Hydration and heat stroke checks are strongly enforced as well. The American army does similar if I’ve been told correctly.
How American civilians and labourers are not allowed these very same standards is insane to me. People die because of this shit and unions are just okay with this?
