Organisations should be prepared for weather extremes that could affect their business during the warmer months. We share top tips for managing your staff through this.

There is no maximum workplace temperature

A common misunderstanding arises around workplace temperatures. While there is no law on either a maximum or minimum temperature, government guidance suggests a minimum of 16°C for sedentary work or 13°C for physical work but there is no maximum temperature. Nevertheless, that doesn’t mean employers can turn a blind eye to the mercury rising.

Employers have a legal obligation to make sure the working environment is safe and comfortable. This means that depending on the type of work being performed, and its location, action is still likely to be needed. Outdoor workers could be given extra breaks and provided with water, sunscreen and access to a shaded area. For inside workers, unless the air conditioning is working properly it can quickly become stuffy. Employers should be checking in with staff, including homeworkers, that they have what they need to stay safe. Where there is something that can be done that is under the employer’s control, such as maintaining or fixing air conditioning or inviting homeworkers to the office, this should be done as soon as possible.

Maintaining productivity in high temperatures

Research has found that high temperatures can cause a reduction in productivity levels, so it’s useful to introduce measures and incentives to keep teams motivated. An early finish for the best-performing person can be a great way to drive team performance. Small treats, such as ice creams or cold drinks to keep staff refreshed, can also go a long way in helping them feel appreciated.

Another option is relaxing dress codes, which can be an easy and achievable measure to immediately alleviate staff discomfort. Allowing loose, breathable fabrics can make a real difference. Where there is a uniform in place, consider giving staff the option of switching out certain items if they want to. For example, rather than requiring black jeans, accept any pair of black trousers. Extending this further to dresses/skirts and, where appropriate, shorts, can help further.

Desk fans can also be provided, as well as allowing extra breaks. Even in office environments, staff can still easily slump if they don’t have adequate time to take a rest break and grab a drink. Finally, pulling down blinds and moving working areas out of direct sunlight can help reduce temperatures as much as possible.

Protecting pregnant employees and those with other health conditions

Pregnant employees, those going through the menopause and staff with other health issues may be particularly at risk during hot weather and may need additional adjustments to keep them safe and comfortable. The best approach in this situation is to meet with the employee to understand what adjustments would help them the most. A pregnancy risk assessment should outline any measures needed for pregnant employees during high temperatures.
