Understanding Behaviour Through Staff Change in PBS: Protecting Trust When Support Teams Shift
Positive Behaviour Support requires services to understand how staff change affects behaviour. The Positive Behaviour Support knowledge hub supports providers to connect behaviour, communication, proactive planning, rights and reduction of restrictive practice.
In specialist services, understanding behaviour through PBS means looking closely at what happens when familiar staff are absent, agency staff are introduced, rotas change, or key relationships shift. Behaviour may increase when support feels unfamiliar, unpredictable or unsafe.
This reflects PBS principles and values, because people should not be expected to adapt instantly to workforce changes that affect trust, communication and emotional security. Strong services plan staff change around the person, not only around rota pressure.
Concept Explained Clearly
Staff change means any shift in who provides support, how familiar they are, what role they take, and how consistently they follow the person’s plan. This may include new starters, agency workers, sickness cover, changes in keyworker, staff turnover or different staff leading personal care, medication, meals or community access.
Behaviour linked to staff change may include refusal, withdrawal, repeated questions, pacing, aggression, avoidance of personal care, increased reassurance-seeking or reduced participation. These behaviours may communicate uncertainty, lack of trust, fear of being misunderstood or anxiety about whether the new staff member will follow known routines.
Why It Matters in Real Services
When staff change is misunderstood, services may treat behaviour as sudden deterioration rather than a response to disrupted relationships. A person may be described as resistant to agency staff when the real issue is that unfamiliar staff have not been introduced properly, briefed fully or supported to use the PBS plan.
Staff change is unavoidable in real services, but poor management of it creates risk. Personal care may be refused, medication routines may become unsettled, community access may reduce and incidents may increase. Commissioners and CQC will expect providers to show that workforce arrangements protect continuity, safety and person-centred support.
What Good Looks Like
Strong services demonstrate that staff change is planned, communicated and reviewed. Staff profiles, communication needs, preferred approaches, relationship risks and high-sensitivity routines are clearly documented. New or temporary staff do not lead complex support without preparation.
Good PBS practice protects the person’s trust. Familiar staff introduce unfamiliar staff, routines remain predictable, communication is consistent and higher-risk tasks are not handed over casually. Providers should be able to evidence how staff change is managed and how outcomes are monitored.
Operational Example 1: Agency Staff and Morning Personal Care
Step 1 – Presenting issue: A person in supported living began refusing morning personal care when agency staff covered sickness. They turned away, shouted and locked the bathroom door.
Step 2 – Support risk explored: The provider reviewed rota records and found that unfamiliar staff were being introduced during the most sensitive part of the day, without enough briefing or relationship-building.
Step 3 – Practice changed: Agency staff were no longer assigned to lead morning personal care on first shift. A familiar worker completed the introduction, explained the routine and remained nearby until the person showed comfort.
Step 4 – Daily delivery detail: Temporary staff received a one-page PBS briefing covering communication, privacy, pacing, preferred wording and signs of distress. They observed before taking an active role.
Step 5 – Evidence and outcome: Refusals reduced, personal care became calmer and staff records showed better use of the agreed approach. The provider evidenced that workforce planning directly improved dignity and reduced distress.
Deepening the Understanding: Familiarity Is Part of Support Quality
Familiarity is not a luxury in specialist PBS services. For many people, familiar staff provide emotional safety, communication understanding and confidence that routines will be respected. When this changes suddenly, behaviour may show that the person is unsure whether they will be heard or supported properly.
This does not mean only familiar staff can ever provide support. It means unfamiliar staff need structured introduction, clear guidance and realistic expectations. Strong providers build resilience into the team without ignoring the person’s need for trust.
The related guidance on seeing behaviour as communication in PBS reinforces why distress around unfamiliar staff should be understood as information about safety, trust and support quality.
Operational Example 2: Staff Turnover Affecting Community Access
Step 1 – Pattern identified: A person receiving outreach support stopped attending weekly community activities after two familiar staff left the team. They repeatedly said “no,” stayed in their room and became distressed when new staff mentioned going out.
Step 2 – Meaning considered: The provider recognised that the activity itself was not the only issue. The person associated community access with trusted staff who understood routes, pacing and reassurance needs.
Step 3 – Support rebuilt: New staff completed relationship-building visits before leading outings. The first community trips were shortened and followed familiar routes. The person chose which new worker supported each step.
Step 4 – Continuity strengthened: The service created a community access profile covering preferred routes, difficult locations, calming strategies and return-home routines. This reduced reliance on staff memory.
Step 5 – Outcome reviewed: The person gradually resumed community activity. Records showed fewer refusals and improved confidence with two new staff. The provider evidenced that continuity planning protected access after workforce change.
Systems, Workforce and Consistency
Staff change must be managed through systems, not goodwill. Strong services use rota planning, induction, shadowing, PBS briefings, supervision and handovers to protect consistency. Managers should know which routines are relationship-sensitive and which staff changes require additional preparation.
Supervision should review whether staff feel confident using individual PBS plans. Handovers should not simply list incidents; they should explain what communication worked, what the person may be worried about and how unfamiliar staff should approach support. This keeps staff change from becoming behaviour risk.
Operational Example 3: New Keyworker and Reassurance-Seeking
Step 1 – Concern noticed: In a residential service, a person began asking repeated questions and seeking staff attention after their keyworker changed. They became distressed when the new keyworker was unavailable.
Step 2 – Relationship impact reviewed: The team identified that the previous keyworker had provided predictable emotional reassurance. The change had not been explained clearly enough, and the person was unsure what the new relationship meant.
Step 3 – Transition planned: The service introduced a keyworker transition plan. The previous and new keyworker completed two joint sessions, used a photo schedule and explained what would stay the same.
Step 4 – Boundaries made predictable: The new keyworker agreed regular check-in times and used consistent language about availability. Other staff followed the same explanation when the keyworker was off shift.
Step 5 – Evidence captured: Repeated questioning reduced, the person attended planned keyworker sessions and distress linked to staff availability decreased. The provider evidenced that relationship transition needed active support and review.
Governance and Evidence
Governance should show how staff change is assessed, planned and reviewed. Providers should be able to evidence rota risk reviews, induction records, PBS briefings, shadowing arrangements, supervision notes, incident analysis and outcome monitoring.
Strong governance connects workforce decisions to behaviour outcomes. Records should show when staff changes occurred, what preparation was provided, how the person responded and whether additional support was needed. This creates a clear line of sight from workforce change to behaviour risk, from behaviour risk to support action, and from support action to outcome.
Commissioner and CQC Expectations
Commissioners expect providers to manage staff change because continuity affects stability, safety and trust. They need assurance that rota pressures do not undermine PBS delivery or increase avoidable incidents.
CQC will expect safe staffing, person-centred support and effective leadership oversight. Inspectors may review whether staff are competent, whether agency workers are briefed, whether care plans are followed and whether incidents linked to staffing lead to learning. Strong services demonstrate that staff consistency is actively governed.
Common Pitfalls
- Introducing unfamiliar staff during sensitive routines without preparation.
- Assuming agency staff can follow complex PBS plans without briefing or shadowing.
- Relying on familiar staff memory instead of clear written guidance.
- Failing to explain keyworker or rota changes in ways the person understands.
- Recording increased behaviour without linking it to workforce changes.
- Treating staff consistency as a preference rather than a support need.
Conclusion
Understanding behaviour through staff change helps PBS teams protect trust when support arrangements shift. Behaviour may show that the person needs more preparation, clearer communication, familiar routines or gradual relationship-building before new staff take on key support tasks.
Strong providers manage staff change as part of PBS governance. They evidence how continuity, briefing, shadowing and supervision reduce distress and protect outcomes. This gives people safer support and gives commissioners and CQC confidence that workforce change is managed with skill and accountability.
