Job sharing: how employers can make one role work for two people

Define the shared role before dividing the week

GOV.UK describes job sharing as two people doing one job and splitting the hours. Start by identifying the service the role must provide: customer availability, recurring deadlines, decisions, supervision and tasks that cannot wait until a particular person returns.

Our practical recommendation is to map a normal week and a difficult week. For the coordinator role, include order queries, urgent complaints and the Friday dispatch cut-off. Decide which activities either partner can handle and which need specialist knowledge or a named lead. A shared job title does not make every task interchangeable.

Recruit against the same essential role requirements, while checking the skills each person brings. Ask how candidates would communicate an unresolved issue and respond to a decision made in their absence. Avoid using personal similarity as a substitute for evidence that they can work together.

Keep the request process separate from the design discussion

Employees in Great Britain can make a statutory flexible working request from their first day. Acas says employers must handle requests reasonably, consult before refusing or partially accepting, and reach a final decision, including any appeal, within two months unless an extension is agreed. A refusal needs a genuine permitted business reason, not a blanket view that job shares never work.

Discuss evidence about the proposed arrangement: coverage gaps, recruitment prospects, cost and customer demand. If the request relates to disability, the reasonable-adjustment duty is separate and must also be considered. An informal conversation should not obscure a statutory request or its deadline.

Use the design work below to test what is possible. If recruiting a partner or running a trial will take longer, agree any necessary extension explicitly and record it. Do not leave the employee waiting indefinitely while you advertise.

Budget for a real handover, not invisible extra work

Our recommended rota includes time to prepare and receive the handover within agreed paid working hours. Work out whether an overlap is needed, what it costs and which tasks should happen during it. Two people discussing work are using two people's time; an overlap does not create extra customer coverage.

For illustration, a business needs 37.5 hours of weekly coverage. If both partners work 20 hours and overlap for 2.5 hours, the arrangement provides 37.5 distinct hours of coverage but costs 40 staff hours. The employer should assess that extra 2.5 hours against continuity, retained knowledge and service needs. This is an example, not a prescribed staffing formula.

Agree where urgent work goes when neither partner is available. Do not build the arrangement around unpaid messages on non-working days. A manager needs an escalation route that works without either person constantly checking their phone.

Use one record and make decision rights visible

A useful handover records the next action, deadline, owner and reason for any important decision. Keep it in an approved shared system, with appropriate access for the role. A list of emails forwarded without context will quickly become another queue to investigate.

In our coordinator example, a delayed order entry might say: supplier confirmation due Thursday at noon; contact the customer by 2pm; agreed alternative already recorded; escalate a second delay to the operations manager. The incoming partner can act without reconstructing the conversation.

Agree which decisions either person can make, which require consultation and who resolves disagreement. Tell colleagues and customers how to contact the role and who is on duty. Shared responsibility should not mean asking both people for approval of every routine action. Review an awkward handover together before it becomes a recurring complaint.

Record individual terms and keep opportunities fair

Acas says agreed flexible-working changes usually alter contractual terms and changes must be put in writing within one month of agreement. Record each person's hours, pay, working pattern and relevant responsibilities, alongside the shared operating arrangements. Distinguish an agreed temporary trial from a permanent change, including the review date and what is agreed to happen afterwards.

Part-time workers are protected against less favourable treatment than comparable full-time workers simply because they work part time, unless objectively justified. GOV.UK identifies pay rates, holidays, training and promotion among the areas covered. Apply proportional entitlements where appropriate; do not assume every benefit or opportunity can simply be halved.

Our practical check is whether each partner can access briefings, development and meaningful feedback during their working time. Assess individual performance fairly as well as the shared service outcome. Do not automatically blame the person who discovers an error, or give all development opportunities to whoever happens to attend the usual Monday meeting.

Plan absence and a partner leaving before either happens

Agree how annual leave, sickness and other absences will be covered. Our recommendation is a manager-owned contingency plan, rather than an expectation that the other partner automatically works full time. If extra hours are proposed, discuss availability and the applicable terms before relying on them.

Civil Service Careers recommends agreeing the procedure for a partner leaving in writing at the outset and not pressuring the remaining person to increase their contracted hours. Its guidance is an employer example, not a universal contractual rule for every business, but the planning principle is useful.

For an SME, the plan might include advertising the vacant share, agreed temporary support and a review of the work while recruitment continues. If a replacement cannot be found, consult the remaining employee about realistic options and take advice before changing contractual hours or considering termination. One resignation should not trigger an improvised assumption that the other person's job ends too.

Review the service, not just whether the rota is filled

Acas recognises trial periods as a way of checking whether a flexible arrangement works. Agree what the trial is intended to test, the review arrangements and any extension to the statutory decision period that is needed. A trial should produce useful evidence, not postpone a decision without agreement.

Our suggested measures are missed deadlines, repeat customer explanations, unresolved handovers, extra hours and access to team information. Ask each partner separately what is working, then discuss shared improvements. A problem caused by an unclear escalation route may need a process correction, rather than abandonment of the job share.

The job-share launch checklist

Official UK primary sources checked on 11 November 2026. Employment-law points concern Great Britain; Northern Ireland has a separate framework. Acas confirms that the existing flexible-working Code continues to apply while the revised Code and legal changes await commencement. The coordinator scenario, hours calculation and launch checklist are practical illustrations and recommendations, not prescribed legal forms.

• Map the service hours, deadlines and essential role requirements.
• Handle any statutory request on time and consider adjustment duties.
• Agree paid handover time, its cost and a shared record.
• Define decision rights, escalation and the contact route for colleagues.
• Record individual terms, fair entitlements and development access.
• Plan absence cover and the process if one partner leaves.
• Set review measures and follow up the evidence.
