YANBU.
They need to get a grip. I had to grapple with similar issues a few years ago with a manager in HR, who should have known better, and I metaphorically ended up giving her a bloody nose in the process. I’ll post separately about that.
My advice from both an HR and H&S background.
Take the steps you feel will enable you to reduce the impact of heat stress symptoms when it comes to clothing. If you get any nonsense, tell them you’re following guidance from the HSE - https://www.hse.gov.uk/temperature/employer/how-you-keep-comfortable.htm I strongly recommend you read that page.
Take more comfort breaks. Again featured in the HSE guidance - “Take regular breaks to cool down in hot conditions.”
PP who mentioned the Health & Safety at Work etc. Act 1974 was right to. There’s a broad duty for employees under it to take reasonable care for the health and safety of your own self. Heat stress presents risks. All you’re doing is your own part in managing them.
The Workplace (Health, Safety and Welfare) Regulations require employers to provide a reasonable indoor temperature in the workplace. You’ll get idiot managers being uppity about this - “how can we control the weather” - but there are obvious things they can do when workplace temperatures are uncomfortable for workers. It is required under the Management of Health and Safety at Work Regulations too.
The HSE’s guidance on what employers should be doing when staff report uncomfortable working temperatures is to assess the risks, talk to staff and agree control measures. Lo and behold a bullet point within the HSE guidance:
- relaxing formal dress codes to allow fewer or more layers of clothing
It’s also notable the first thing suggested in the HSE guidance about what workers can do is to add or remove layers of clothing. Wearing clothing that is more appropriate to the temperature is keeping in with the spirit of that.
Putting it bluntly, what you’re proposing to do OP is basic common sense. it’s also backed up by legal requirements and guidance from the regulator of H&S in the UK. There are obvious reasons why they’ve put this guidance out there.
Here’s a link from HSE about heat stress at work - https://www.hse.gov.uk/temperature/employer/heat-stress.htm Isn’r it telling the example of “ a typical heat stress situation” they give is someone who has to wear protective clothing but is working in hot and humid conditions.
Particular emphasis on the bullet points under that section:
- sweating is restricted by clothing and humidity…
- the body reacts by producing more sweat, which may cause dehydration
For the benefit of obtuse managers, you don’t have to be wearing protective clothing to encounter the same issues.
If you wanted to try and get a step ahead of these berks of managers, email your manager and CC the berks in. Report the temperatures recorded in the office and symptoms you’ve all experienced; ask for details about the revised controls in place on account of the extreme weather conditions and the unreasonably high temperature in the workplace. There’s even a handy heat stress checklist they can work through https://www.hse.gov.uk/temperature/assets/docs/heat-stress-checklist.pdf
