Why hydration matters for health, safety, and rights on the job
Whether you are in a hospital, behind the wheel, on a build site, or at a desk, proper hydration is a matter of health and safety, not just personal choice. Staying hydrated will keep you alert, reduces risk of heat stress and fatigue, and protects your long-term health.
Employers have a legal duty to provide drinking water and ensure safe working conditions but we must also look out for ourselves and each other.
Guidance on keeping hydrated
Drink water regularly, not just when you’re thirsty
Thirst is a late sign of dehydration. Sip water throughout your shift, especially if you’re working in heat or doing physical labour.
Use a reusable water bottle or flask
It’s an easy way to track your intake and stay topped up. Many workplaces allow or even supply these, if not, ask if you can use one.
Take extra care in hot environments
Outdoors? Near machinery? Kitchens? Warehouses? Hydration is critical in high-temperature areas. Combine with regular breaks and shade where possible.
Speak up if water access is limited
Employers are legally required to provide clean drinking water. Raise it with your manager of mention it to the WEU office, if water is unavailable or access is restricted.
Eat water-rich foods if you can
Fruits and vegetables help keep hydration levels up. A packed lunch with cucumber, tomatoes, melon, or oranges helps.
Look out for colleagues
If someone looks flushed, dizzy, or confused, it could be heat stress or dehydration. Know the signs and act early.
Be aware of the following points
Don’t rely on energy drinks or fizzy pop
They can dehydrate you further, especially ones high in caffeine or sugar. They’re not a substitute for water.
Don’t skip water to avoid toilet breaks
This is common but dangerous. Your body still needs water and your employer should allow time and access for breaks. If not, it’s a health and safety issue.
Don’t “pre-load” with caffeine or use alcohol before a shift
Coffee, tea and alcohol can dehydrate you. Stick to water, especially before and during work.
Don’t stay silent if workplace conditions are unsafe
If there’s no water provided, or breaks are denied in hot conditions, report it. This is a Trade Union issue, your safety is a right, not a privilege.
Don’t ignore signs of dehydration
Headaches, dry mouth, dizziness, tiredness, or dark urine? Time to drink and rest. Pushing through puts you at risk.
WEU message – Hydration is a Health & Safety Issue
