The Behavioural Science and Insights Unit (BSIU) recently produced a briefing document which looks at the behaviours of transmission reduction in retail, this for staff in wearing face coverings, social distancing and handwashing/sanitising. In addition, they look at 3 customer behaviours. They state social distancing is the most prevalent problem followed by not making the rules clear to employees and customers using signage and markings, and not communicating public health guidelines to staff.
The document gives a breakdown of reasons why businesses contacted have failed Health and Safety Executive / Local Authority spot checks for COVID-19 controls: 7926 of 12,000 businesses contacted have failed Stage 1 spot checks and the highest proportion due to failure to engage in the process.
Although face coverings are not covered in HSE spot checks and there is limited data on adherence to the use of face-coverings in retail, especially in the UK. Between August and November 2020, self-reported face covering usage in Great Britain was consistently above 90% and Office of National Statistics (ONS) data from December 2020 showed that 97% of adults said that they had used a face covering outside their home in the past week.
