Type 1 at work: your rights, disclosure, and reasonable adjustments in practice
Do I have to tell my employer I’m Type 1, and what adjustments am I actually entitled to at work?
In England, Scotland and Wales, Type 1 diabetes is protected as a disability under the Equality Act 2010, even when you manage it well, because the law looks at what would happen without your insulin and monitoring rather than at how healthy you are day to day. That protection means an employer must not treat you unfairly for your diabetes, and must consider reasonable adjustments, practical changes that let you do the job safely, like a break to treat a low or somewhere to test. In most jobs you do not have to tell your employer, with some safety-critical roles the exception. Northern Ireland gives similar protection under its own law.
- The Equality Act 2010 (the equality and disability law for England, Scotland and Wales) treats insulin-treated diabetes as a disability, so it is unlawful to discriminate against you for it.
- The law deliberately ignores how well your treatment works when deciding this, so being fit and healthy does not remove your protection.
- Reasonable adjustments (sensible changes to how or when you work) can include breaks to check glucose or treat a hypo, a place to keep insulin, or time off for clinic appointments.
- In most jobs there is no legal duty to disclose, though telling someone means adjustments are possible and help is there if you have a bad low at work.
- A few safety-critical roles (the armed forces, some driving and emergency jobs) set medical standards that can restrict or rule out insulin users.
Why the law is on your side
The Equality Act 2010 counts a condition as a disability if it would have a substantial, long-term effect on daily life without treatment, and it specifically says you ignore the good that medication does when judging that. Insulin-treated Type 1 fits, however well you are doing, which is the point people often miss: you do not have to be struggling to be covered. In practice that protects you from being turned down, sidelined, harassed or dismissed because of your diabetes, and it puts a duty on the employer to make reasonable adjustments. Northern Ireland is not covered by this Act but gives comparable protection under its own disability law. This is about fair treatment, not about being labelled as ill, and you can use the word disability or not, as you prefer.
Do you have to say anything?
Usually, no. For most jobs there is no legal duty to tell an employer you have Type 1, and the law limits the health questions they can ask before offering you the job in the first place. The trade-off is that some protections and all adjustments only really work once someone knows, and telling a trusted manager or colleague means help is on hand if you ever have a severe low at work. After a job offer, many employers refer you to occupational health, a service that assesses fitness for the role and recommends support, and it is worth being honest there because they are on the side of keeping you working safely. Safety-critical jobs are the genuine exception, where medical standards apply and non-disclosure can matter, so check the rules for that specific role.
Reasonable adjustments in practice
Reasonable adjustments are simply the everyday changes that let you manage diabetes and do your job at the same time. Common ones include a short break to check glucose or treat a hypo whenever you need it, permission to test or wear your CGM at your desk or station, somewhere to store insulin and snacks, flexibility over shift patterns or breaks, and paid time off for hospital and clinic appointments. What counts as reasonable depends on the job and the size of the employer, so a big company can usually do more than a tiny one, but the duty to consider it always applies. An occupational health report can spell out what would help, which makes it much easier for a manager to say yes and to put it in place properly.
When an employer will not play ball
If a reasonable request is brushed off, put it in writing so there is a record, and ask for it to go through HR or occupational health rather than resting on one manager’s mood. Keep notes of what was asked and what was said. Plenty of support exists beyond your workplace: the Diabetes UK helpline can talk through your rights, ACAS gives free, impartial advice on workplace disputes in England, Scotland and Wales, and a union will represent you if you are a member. Most problems are sorted long before this, but if discrimination is serious and cannot be resolved, an employment tribunal is the formal route. Knowing these paths exist tends to make the earlier, calmer conversations go better, because you are asking from a position of knowing where you stand.
What changes how this plays out
No two jobs are the same, and the right adjustments depend on yours. A desk role and a warehouse or driving role raise completely different issues, and a large employer can usually offer more than a very small one. Shift and night work deserve a special mention, because they move your glucose in both directions: changing sleep, meal timing and activity can send you high or low and can bring on lows at awkward hours, sometimes well after a shift ends. How you handle insulin around shifts is worth planning with your diabetes team rather than winging it.
How it comes up at work
Examples, not instructions or doses.
You feel a hypo coming on partway through a busy shift and need to stop, sit down and treat it. An agreed adjustment to take a break whenever this happens turns a stressful moment into a normal one.
You get the offer, then a health questionnaire from occupational health. Answering it honestly lets them set up the support that keeps you safe, rather than it being something to hide.
You want a job with medical standards, such as certain armed forces or emergency roles. These have their own rules on insulin, so the honest first step is checking exactly what that role requires.

Questions that make an appointment useful
When it's urgent
Make sure someone at work knows what a severe hypo looks like, because it is the one workplace emergency worth planning for. If a colleague finds you confused, unable to swallow safely, fitting, or unconscious, they must not try to put food or drink in your mouth. They should call 999 straight away, say you have Type 1 diabetes and are having a hypo, use glucagon if someone is trained to, and put you in the recovery position while they wait. Testing must never delay that call. Writing this down for your team in advance means the right help happens fast on the day it is needed.
