Night Shifts and Pregnancy: Your Rights, Explained

Last updated: 20 August 2026 · ~1,250 words

Finding out you're pregnant while working nights raises a very practical question fast: do you have to keep doing them? The short answer is no, not if they're not safe for you — but the process for getting that changed is specific, and knowing it in advance makes the conversation with your employer much easier than winging it.

This is a guide to the process and your rights, not medical advice. Whether night work is a problem for your particular pregnancy is a conversation for your midwife or GP.

The first step is telling your employer

Nothing changes automatically until your employer knows you're pregnant. Once you've told them — formally, ideally in writing so there's a record — they have a legal duty under UK health and safety law to carry out an individual risk assessment covering you specifically, not a generic policy document. That assessment has to look at your actual job, your actual shifts, and any risks night work might pose to you or the pregnancy.

You're entitled to request this assessment yourself if it hasn't happened. You don't have to wait for HR to remember.

What the law says about night work specifically

There's a specific provision — Regulation 17 of the Management of Health and Safety at Work Regulations — that deals with night work during pregnancy. If a doctor or midwife certifies in writing that night work would affect your health and safety, your employer is legally required to either:

  • move you to suitable day work on the same terms, or
  • if that's genuinely not possible, suspend you from work on full pay for as long as necessary.

The key trigger is that written certification from a doctor or midwife. It's worth raising the night-shift question directly at a midwife appointment if you're at all unsure, so you have that document if you need it.

If a risk is identified

Where the risk assessment turns up a genuine risk — whether that's the night work itself, or something else about the role like heavy lifting, prolonged standing, or exposure to certain substances — your employer must do what's reasonably practicable to remove it. In order of preference, that generally means:

  1. Adjusting your working conditions or hours to remove the risk.
  2. Offering suitable alternative work on your normal terms and pay, if adjustment isn't possible.
  3. Suspending you on full pay, if neither of the above is workable.

What your employer can't legally do is simply leave you on an unsafe rota because reorganising it is inconvenient, or quietly push you out. Unfavourable treatment connected to a pregnancy-related health and safety issue is unlawful, and if you lose pay because your employer failed to act properly, that can be a matter for an employment tribunal.

What "unsafe" actually means here

There's no blanket rule that says pregnant workers can't do nights. It depends on your individual circumstances, your specific role, and what your risk assessment and your midwife or GP actually say. Fatigue, standing for long periods, manual handling, and reduced access to breaks or rest facilities are common factors that come up in these assessments for shift-based roles — but the honest answer is that a proper individual assessment is the only way to know what applies to you.

Starting the conversation

A few things that tend to make this go more smoothly:

  • Tell your employer in writing as well as verbally, so there's a clear record of when the clock started on their duty to assess.
  • Ask directly for the risk assessment rather than waiting for it to be offered — not every workplace runs this process proactively.
  • Raise night work specifically with your midwife at an early appointment, so you have written guidance to hand if your employer needs it.
  • Keep a note of dates and conversations — when you told your employer, when the assessment happened, what was agreed. It's unlikely you'll need it, but it matters if you do.

Where to get proper advice

This page explains the process, but it isn't a substitute for advice on your specific situation. Maternity Action and Working Families both run free advice lines for UK workers on pregnancy and workplace rights, and are worth contacting if your employer is pushing back or the situation feels unclear.

Once things are settled

If your shifts do change — moving to days, a lighter pattern, or a temporary adjustment — it helps to see the new rota mapped out properly rather than working it out week to week. The MyShiftCalendar tool generates a full year of whatever pattern you're actually on, free, with nothing stored beyond your own device.
