Department of Health and Social CareOn-call, out-of-hours work and additional duties
Identify what is already contracted, how availability differs from work done, and how to agree extra activity safely.
On-call availability, work actually performed, premium-time rules and additional voluntary work are not interchangeable. Read the relevant contract and rota together. Agree the duty, frequency, time, rest, payment, cancellation and review before recurring extra work begins wherever possible.
By the end of this module, you should be able to:
- Distinguish availability from work performed.
- Analyse safe hours and compensatory rest.
- Agree extra work without creating hidden permanent duties.
Availability and actual work
An on-call availability supplement may pay for being available at specified frequency and category. It does not necessarily pay every hour of work performed or replace job-planned time for predictable emergency duties. Contract definitions differ by nation and version.
Use call data to test intensity: contacts, returns to site, remote decisions, time and next-day effect. If intensity changes materially, request rota and job-plan review.
- Read the supplement definition.
- Measure actual work separately.
- Review increased intensity.
Additional work
Extra contractual work should be explicit about activity, rate, duration, cancellation, indemnity, pensionability, rest and tax. Clarify whether it is an additional contracted unit, internal bank/locum work or a separate arrangement. The label affects neither safety nor tax by itself.
Repeated ‘temporary’ cover may reveal a substantive workforce need. Review the base job plan and recruitment solution rather than relying indefinitely on voluntary extra work.
- Put rate and scope in writing.
- Protect rest and primary duties.
- Review recurring service dependence.
Safe hours and rest
Working Time rules provide a statutory framework including average weekly limits, rest and paid annual leave, subject to detailed provisions. Some doctors opt out of the average limit, but an opt-out does not remove the employer’s health and safety duties or every contractual safeguard.
Combine all work when assessing fatigue, including bank, locum and work for other employers. If fatigued, use immediate patient-safety escalation and do not drive if unsafe. Address recurring rota design separately.
- Count work across employers.
- Opt-out is not a waiver of safety.
- Escalate fatigue before harm.
Prospective cover and leave
Rota arrangements may include prospective cover for colleagues’ leave, meaning the frequency of work while present can be higher than a simple one-in-n calculation. The contract should explain how this is recognised. Check whether annual leave, study leave and vacancies are included in the rota calculation.
A vacancy is not automatically ordinary prospective cover. Sustained gap cover should be risk assessed, time limited and addressed through recruitment and job planning.
- Understand the rota denominator.
- Distinguish planned leave cover from vacancies.
- Review sustained intensity.
When to decline or escalate
Doctors should not accept work beyond competence, without necessary support or when fatigue creates serious risk. Raise the specific concern, seek senior clinical direction and propose a safe alternative. Immediate patient abandonment is not an employment remedy.
For non-urgent additional work, a clear response can state existing commitment, safety or rest constraint and conditions under which the work could be accepted. Seek advice where refusal might have contractual consequences.
- Describe the safety constraint.
- Offer a safe alternative where possible.
- Get advice on disputed contractual duties.
Does your rota description match the real frequency, intensity and next-day effect of the work?
Three takeaways
- 1Availability, actual work and extra work are different pay concepts.
- 2Count total working time and protect rest.
- 3Recurring extra work needs a written and reviewable arrangement.
