What to do if…
your work schedule changes to nights or weekends with little warning

What to do now

1. Save proof of the change. Screenshot the old rota, new rota, app notifications, texts, emails, and any message saying you must work the new nights or weekends. Note the date, time, who told you, and when the new pattern is supposed to start.

2. Check the documents that control your shifts. Look at your contract, written statement, staff handbook, rota policy, and any union or collective agreement. Check especially for normal hours, days of work, night work, Sunday work, overtime, flexibility clauses, how rotas are issued, and how much notice your workplace says it will normally give.

3. Ask for the change in writing. If you were told verbally, send a short message to your manager or HR: “Please confirm the new shift pattern, start date, whether it is temporary, how long it is expected to last, and how rotas will be issued or changed.” If the change affects details in your written statement of employment particulars, ask for the updated written particulars; employers must tell employees or workers about changes to the written statement within one month of making the change.

4. Reply with practical constraints, not a long argument. If nights or weekends cause a real problem, write down the specific issue: childcare, caring duties, transport, personal safety, health, study, or another job. Say what you can cover, what you cannot cover, and one workable alternative, such as a shorter temporary cover period, different days, a shift swap, or a phased start. Ask for a short meeting.

5. If the new shifts include nights, check the night-work rules. Staff who regularly work at least 3 hours during the night period are night workers. The night period is usually 11pm to 6am, unless a different 7-hour period including midnight to 5am has been agreed in writing. Night workers must not work more than an average of 8 hours in each 24-hour period; the average is usually calculated over 17 weeks, but can sometimes be longer by agreement. Your employer must offer a free health assessment before you become a night worker and regular assessments after that; you do not have to accept.

6. Check rest between shifts before saying yes. Workers over 18 are usually entitled to 11 hours’ rest between working days, weekly rest, and one uninterrupted 20-minute rest break during a working day of more than 6 hours. Some exceptions can apply, so write down the exact finish time and next start time if the new rota leaves you too tired or unsafe.

7. If the weekend shift is a Sunday, check whether Sunday rules apply. In general, Sunday working depends on your contract or written statement, and a worker cannot be made to work Sundays unless they agreed this with their employer and put it in writing. If you work in a shop or betting shop, there are specific Sunday opt-out rules, so check those before signing or agreeing to a new Sunday pattern.

8. If you decide to cover some shifts for now, protect the paper trail. If you work the new shifts to reduce immediate disciplinary risk, write that you are doing so temporarily and working under protest while the issue is discussed. Say clearly that you do not agree to a permanent change to your contracted hours or shift pattern. Repeat the objection in writing while the disagreement continues.

9. Bring in support early if pressure is increasing. If you have a union or staff representative, contact them and share the screenshots. If you do not, contact Acas for practical next steps, especially if you are being pressured to sign, threatened with discipline, or told the change has already happened without your agreement.
