Working 12-hour shifts

A 12-hour shift pattern fits a full-time week into about three shifts instead of five, which means more days off and fewer commutes. Each working day is long and tiring, with little left over for anything else, and some staff find that recovery eats into the days off. Whether it suits you depends on your health, your commute, your caring responsibilities and how well the shifts are staffed.

Where 12-hour shifts are used

Long days and long nights are standard on many hospital wards, in intensive care, in maternity units and in A&E. Ambulance services, police response teams, fire control rooms, prisons and residential care also use them. In most of these jobs the service sets the pattern and you do not choose it. Some wards mix long days with shorter earlies and lates, which gives a bit more choice.

The actual shift is usually a little longer than 12 hours once handover is included, and the paid hours are usually a little shorter because of an unpaid meal break. Check how your trust counts it: the difference across a year adds up, and it affects how many shifts make up your contracted hours.

The advantages

The main advantage is time. With three long days you have four days off in a week, which helps with childcare, study, a long commute or a second job. Fewer shifts mean fewer journeys, which saves on fuel, fares and parking.

Fewer handovers can also help patients, because the same nurse or paramedic covers a whole day, and some staff find it easier to get to know patients and finish tasks without passing them on halfway.

For people with caring responsibilities, a block of days off can be easier to organise than a short shift every day. Rotas can sometimes be arranged so that shifts fall on days when another parent or relative is at home.

The disadvantages

Fatigue is the main one. Concentration tends to drop towards the end of a long shift, especially on nights, and tired people make more mistakes. Driving home after a long shift carries its own risk. If you are falling asleep at the wheel, stop somewhere safe; tell your manager if it keeps happening.

Working days are mostly lost to the job. With travel, a 12-hour shift can take up 14 hours or more of your day, leaving time for little except eating and sleeping. Three in a row can be draining, and the first day off is often spent recovering.

Breaks often suffer in practice. You are legally entitled to at least a 20-minute rest break when you work more than six hours, and most NHS long days include a longer unpaid meal break. On a busy shift these can be cut short or missed. Regularly missed breaks are a safety issue. Report them through your manager or the trust’s incident system so that they are recorded.

Long shifts also make sickness and family emergencies harder to absorb. Swapping a single 12-hour shift is a bigger favour to ask than swapping a short one.

Rest rules that apply

The Working Time Regulations say you should not average more than 48 hours a week over 17 weeks unless you have opted out in writing. On a rota of 12-hour shifts it is easy to go over that if you also pick up bank shifts. You should normally get 11 hours’ rest between working days and 24 hours off each week or 48 hours each fortnight. Health services can vary daily rest where patient care requires it, but only if you get equivalent compensatory rest later.

Night workers have additional protections, including a limit on average hours and the right to a free health assessment. Working nights explains those.

Making long shifts more manageable

Some practical habits help. Eat proper meals on your break rather than grazing, keep water with you, and protect your sleep before and after a block of shifts. The NHS website has advice on the effects of poor sleep, and your trust’s occupational health service can advise if you are struggling.

Ask for your rota preferences to be considered. Many rostering systems let you request patterns such as no more than three long days in a row, or keeping nights together. If you need a specific pattern for health reasons, ask occupational health to recommend it; that carries more weight than a personal request.

If long shifts are not working for you, you can make a flexible working request from your first day, asking for shorter shifts, fewer shifts or set days. Part-time staff on long-day rotas have the same rights as full-time staff on a pro rata basis; see part-time workers’ rights. Some areas, such as outpatients, day surgery, community teams and admin roles, work standard days. NHS shift patterns describes the other shift types and how rotas are put together, which helps if you are deciding between ward and non-ward posts.
