Telling work about your diabetes: what you owe them, and what they owe you

One of the most common questions in Type 1 communities has nothing to do with insulin or carbs. It is this: do I have to tell work? People ask it before a first day, before an interview, and after years of quietly saying nothing. The answers they give each other are honest, mixed, and worth reading before you decide.

The question that comes up again and again

Scroll any Type 1 forum and the same worry surfaces, in threads with titles like ‘Do you tell your employer?’, ‘How do I tell my boss I have diabetes?’ and ‘Do you inform someone at your job that you’re a diabetic?’. If you have been turning it over yourself, you are in very common company.

Many people describe a real tension. They do not want to be treated differently, or seen as a risk, but they also know that if a bad low ever happened at work, a colleague who understood could matter a great deal. There is no single right answer that fits every person and every job, and the community reflects that. Some people tell everyone on day one. Some tell one trusted colleague and no one else. Some say nothing for years. All of those are legitimate.

What the law actually says in the UK

Here is the part that surprises a lot of people. For the large majority of jobs in the UK, you are not legally required to tell your employer that you have Type 1 diabetes. It is your medical information, and in most roles the choice to share it is yours.

The main exceptions are a handful of safety-critical roles that carry their own medical rules, such as professional driving (lorries and buses), aviation, the armed forces and some emergency services. If your work is in one of those areas, there are specific requirements to check rather than a personal choice to weigh up, and your diabetes team can help you understand them.

The other thing worth knowing is that Type 1 diabetes is generally covered by the Equality Act 2010. In plain terms, that law treats Type 1 as a disability for its protections, whether or not you would ever use that word about yourself. It means an employer is not allowed to discriminate against you because of your diabetes, and it puts a duty on them to make reasonable adjustments (practical changes that help you do your job safely).

Why many people tell someone anyway

Even though the law does not require it in most jobs, a common thread in Type 1 communities is that people are glad, in the end, that they told at least one person. The reason is usually safety.

A hypo (a low blood glucose, when your sugar drops too far) can leave you shaky, confused, or unable to think clearly, and it tends to arrive at the least convenient moment. People often say that having one colleague who knows what a low looks like, and where the fast sugar lives, took a quiet weight off their shoulders. You do not have to brief the whole office. Many people describe simply telling a line manager or a desk neighbour: this is what a low looks like for me, this is what I do about it, and this is the point where you would call for help.

Reasonable adjustments: what work can owe you

Telling someone is also what opens up the adjustments the Equality Act talks about. These are not favours. For a covered condition they are something an employer is expected to consider.

People in the community describe adjustments like being allowed to stop and check glucose or treat a low whenever they need to, keeping snacks and insulin at their desk or in a fridge, a bit of flexibility around meal breaks and shift patterns, and paid time off for clinic and eye-screening appointments. If you work somewhere with an occupational health service, that can be a comfortable route: a confidential conversation that turns ‘I have Type 1’ into specific, agreed adjustments, without you having to negotiate each one with a manager. Diabetes UK has clear guidance on rights at work that many people take along to that conversation.

A low at work, and when it stops being routine

Most lows at work are not emergencies. The usual pattern people describe is straightforward: treat it quickly with fast-acting sugar, wait, recheck, and top up with something longer-lasting once you are back up. That is ordinary self-management, and it is a good reason to be allowed a two-minute pause without having to explain yourself.

It becomes different if a low ever gets severe: if someone with Type 1 is so confused they cannot help themselves, cannot swallow safely, has a seizure, or passes out. That is a 999 emergency, and it needs an ambulance straight away, not a wait-and-see. This is the honest reason so many people land on telling at least one colleague. Not because a bad low is likely, but because if it ever happened, you would want the person next to you to dial 999 rather than assume you had simply fainted.

There is no perfect script

If you are weighing this up, it helps to know that the community has not settled on one answer, and you do not have to either. Some people find it easier to mention it casually and early, before it starts to feel like a big reveal. Others wait until they trust the place. What most people agree on, looking back, is that they would rather one person at work knew than nobody at all.

Whatever you decide, your diabetes team can help you think through the specifics for your role, and Diabetes UK can help with your rights if work does not respond well. You are allowed to share as much or as little as feels right, and you are allowed to change your mind.
