Just so you know, employers are obliged by law to heat inside workplaces for sedentary workers to a minimum of 16 degrees Celsius (63F) and for those who undertake physical work to a minimum of 13 degrees Celsius (58F). If the temperature drops below these levels the employer is obliged by law to bring in additional heaters to raise temperatures to the legal minimum requirements.
For those working outside the employer is obliged to undertake a risk assessment and where necessary provide appropriate thermal clothing and regular breaks for hot drinks. Those exposed to risks of falls in slippery conditions may need to be redeployed to suitable alternative work if gritting cannot be carried out or if the ice cannot be removed.
The GMB says that many of its members in refuse collection and street cleaning have been moved to work with gritting teams.
