A 6.00 am shift is still open. The client needs support, the venue needs a capable opener, or the site cannot operate without cover. Yet the notification has gone out, calls have been made and nobody has accepted. Understanding why shifts remain unfilled starts with looking beyond the assumption that people simply do not want the work.
For most shift-based businesses, an unfilled shift is the final symptom of a process problem. The right person may not have seen it. They may not be eligible, available, confident about the location, or willing to accept a shift that arrives too late with too little detail. When this happens repeatedly, managers spend their day chasing cover instead of running the operation.
Why shifts remain unfilled more often than expected
Labour shortages are real in care, hospitality and other shift-based industries. But they do not explain every open shift. Many businesses have enough people on paper, yet still struggle to fill changes at short notice. The difference is often visibility, timing and trust in the roster process.
A shift that sits unfilled may have been offered to staff who are unavailable, lack the required skills or have already worked enough hours. It may have been sent through a group chat where the message is buried beneath unrelated conversation. Or it may be unclear who is responsible for accepting it, confirming the change and turning up.
For NDIS and aged care providers, there is another layer. Filling a shift is not only about finding any available worker. The person needs the right checks, competencies and relationship fit for the participant. A quick fix that creates a poor client-worker match can damage continuity of care and create more work for the service team.
Hospitality teams face a different version of the same pressure. A busy Friday night cannot wait for a manager to work through a list of contacts one by one. If staff cannot quickly see the shift, understand the role and respond from their mobile, the business loses valuable time when it matters most.
The common causes behind open shifts
The roster is built on assumptions, not live availability
Availability changes. Staff pick up appointments, study commitments, family responsibilities and extra work. If a roster is built from an old spreadsheet, verbal promises or a manager’s memory, it may look covered until someone declines or fails to arrive.
Current availability gives coordinators a more realistic starting point. It helps them avoid offering shifts to people who cannot work and reduces the frustration staff feel when they are repeatedly contacted on their days off. This is not about expecting employees to be available all the time. It is about giving them a simple way to state when they can work, then respecting that information.
The shift reaches the right people too late
Short-notice changes are sometimes unavoidable. A sick call, client request or sudden booking can happen at any hour. But a pattern of last-minute offers usually points to weak planning, delayed approvals or a roster that is published too close to the work date.
The later a shift is offered, the smaller the available pool becomes. Staff may have made plans, arranged childcare or committed to another employer. Advance notice will not solve every gap, but it gives capable people a fair chance to organise their lives around work.
Staff do not have enough information to say yes
A message saying “Can anyone work tonight?” asks staff to take a risk. They need to know the start and finish time, location, role, client or service context, pay conditions where relevant, and any required qualifications. In care settings, they may also need to know whether they are appropriately matched to the participant and whether there are specific support requirements.
Clear details allow staff to make a quick decision. Vague messages create questions, back-and-forth calls and delays. By the time the details are confirmed, the person who may have accepted has already made other plans.
Communication is scattered across too many channels
Text messages, personal messaging apps, phone calls, emails and printed rosters all have their place, but relying on a mix of disconnected channels makes accountability difficult. A coordinator may believe an offer was sent, while the staff member never saw it. Another employee may reply in a private message that nobody monitors after hours.
A single operational channel does more than speed up communication. It creates a record of who was notified, who viewed the request, who accepted and when the roster changed. That matters when clients, managers or auditors need an accurate account of what happened.
The same reliable people are asked every time
When pressure is high, managers naturally call the staff who usually say yes. Over time, those people can feel taken for granted. They may become tired, decline more often or leave for a workplace with more predictable hours.
Fair allocation does not mean every shift can be shared equally. Experience, qualifications, client preferences and contractual hours still matter. It does mean managers should be able to see who has been offered extra work, who has accepted it and where the workload is becoming uneven.
Fix the process before the next urgent change
The most effective response is not a longer call list. It is a roster process that helps the right staff see, assess and accept suitable shifts without a coordinator acting as the switchboard.
Start by making availability easy to keep current. Employees should be able to update their availability from their mobile, while managers can see it when building or changing the roster. Set clear expectations about how far ahead availability needs to be entered and how staff should flag exceptions.
Next, publish rosters as early as practical. There will always be changes, particularly in community services and hospitality, but early publication reduces the number of changes that are genuinely urgent. It also gives staff confidence that their work life is being managed with reasonable notice.
Then make every open-shift request useful. Include the role, time, location, requirements and any information staff need to decide. Send it to eligible, available people first rather than broadcasting blindly. This protects staff from irrelevant alerts and gives the business a better chance of a fast response.
Finally, establish a simple escalation path. If nobody accepts within a defined period, the system or coordinator should move to the next suitable group, notify the relevant manager and document the outcome. The right process depends on the size of your team and the risk of the shift. A support shift for a participant with complex needs should not follow the same rules as an extra floor shift in a café.
Use technology to remove the chasing
Workforce software should reduce administration, not add another system for staff to avoid. The practical test is simple: can a worker check their roster, update availability, receive a shift offer and respond quickly from one place?
A configured platform such as Tommy can bring scheduling, availability, notifications, private business messaging and time clocking into the same operational view. For managers, that means less time reconciling messages and more confidence that the current roster reflects what staff have actually accepted. For employees, it means fewer confusing calls and a clearer way to manage their work commitments.
Implementation matters here. A generic system with every feature switched on can make a straightforward process feel complicated. Workflows should reflect how your organisation allocates staff, manages qualifications, handles client preferences and approves last-minute changes. The goal is not more technology. It is a calmer, more reliable way to get the right people where they need to be.
Measure the gaps that keep returning
Do not treat every unfilled shift as an isolated emergency. Review the pattern each week or month. Are particular locations hard to cover? Do requests go out after a certain time? Are some roles short on qualified staff? Are cancellations concentrated around particular clients, days or managers?
These answers help separate a genuine recruitment problem from a rostering problem. If a particular service consistently needs cover at short notice, you may need a larger qualified pool, different shift times, better handover practices or more realistic staffing levels. If staff decline because shifts are unclear or notification is late, the solution is process discipline rather than another recruitment campaign.
The measure that matters is not simply how many shifts were filled. Look at how they were filled: how much notice was given, how many staff were contacted, whether the worker was appropriately qualified, and whether the change affected client service or staff fatigue.
An open shift will occasionally be unavoidable. A roster that relies on frantic phone calls does not have to be. When availability is current, communication is clear and staff can act quickly, filling work becomes less of a daily scramble and more of a controlled operational process. Happy Staff – Happy Life starts with giving people a fair, simple way to say yes.
