"Some other substantial reason" (SOSR) is a flexible dismissal category for genuine business reasons that don't fit conduct, capability, redundancy, or illegality.
20 Real SOSR Dismissal Examples
1. Client Refuses to Work with Employee
Scenario: A major client tells your employer they will not renew their contract if you continue working on their account.
SOSR grounds: Third-party pressure; genuine threat to business relationship
Likely fair if: Employer investigates client's concerns, considers alternatives, consults with you
Example case: Dobie v Burns International - dismissal fair when US employer required UK employee to return to US
2. Loss of Security Clearance
Scenario: You work in defence industry and lose your security clearance due to new partner's nationality/criminal record.
SOSR grounds: Can no longer perform essential duties
Likely fair if: Employer checked whether alternative work available, followed fair process
Example case: Klusova v London Borough of Hounslow - dismissal fair when employee lost security clearance
3. Imprisonment
Scenario: You're imprisoned for non-work-related offence, making attendance impossible.
SOSR grounds: Unavailability to work (not misconduct)
Likely fair if: Sentence length makes continued employment impossible, employer considered alternatives
Key: This is SOSR, not misconduct, if offence is unrelated to work
4. Business Reorganisation Without Redundancy
Scenario: Company needs all staff to work new shift patterns; you refuse.
SOSR grounds: Genuine business need for reorganisation
Likely fair if: Business need genuine, consulted properly, offered reasonable notice
Example case: Hollister v NFU - dismissal fair when employee refused new terms after consultation
5. Harmonising Terms Post-Merger
Scenario: Two companies merge; old contracts need standardisation; you won't agree to new terms.
SOSR grounds: Business need to harmonise contracts
Likely fair if: Legitimate business reason, proper consultation, new terms reasonable
6. Personality Clash with Manager
Scenario: Irreconcilable personality differences with your line manager affecting work.
SOSR grounds: Breakdown of working relationship
Likely fair if: Employer tried mediation, considered transfer, relationship genuinely irretrievable
Warning: Tribunals scrutinise heavily - must be severe, not just "we don't get on"
7. Breakdown of Trust (Not Misconduct)
Scenario: You didn't do anything wrong, but trust has broken down (e.g., suspected but unproven wrongdoing).
SOSR grounds: Loss of confidence in employee
Likely unfair: Very hard to justify without misconduct; tribunals are skeptical
Red flag: Often seen as pretext for unfair dismissal
8. Third-Party Professional Relationship
Scenario: You're a relationship manager and key client requests your removal (not for misconduct).
SOSR grounds: Maintaining essential business relationship
Likely fair if: Client relationship essential, no alternative role available, fair process followed
9. Regulatory Body Concerns
Scenario: Financial regulator expresses concerns about your fitness to hold a regulated role.
SOSR grounds: Regulatory requirements
Likely fair if: Concern is genuine, you can't do the job without regulatory approval
Example: FCA withdraws approval for senior manager role
10. Refusal to Relocate
Scenario: Business closes your office; you're required to relocate but refuse.
SOSR grounds: Business reorganisation; legitimate business need
Likely outcome: Depends on whether mobility clause in contract and reasonableness of relocation
Fair if: No mobility clause but genuine business need; unfair if mobility clause exists (should be redundancy)
11. TUPE Transfer Refusal
Scenario: Business transfers under TUPE; you refuse to transfer to new employer.
SOSR grounds: Refusal to transfer
Automatically fair: TUPE specifically provides this is SOSR
Note: You're not dismissed by old employer; employment ends by refusal to transfer
12. Conflict of Interest
Scenario: Your partner starts working for direct competitor in same field.
SOSR grounds: Genuine conflict of interest concerns
Likely outcome: Depends on severity and alternatives explored
Fair if: Legitimate confidentiality concerns, alternatives explored
13. Expiry of Fixed-Term Contract
Scenario: Your fixed-term contract expires; task is complete; no renewal.
SOSR grounds: Genuine temporary need has ended
Likely fair if: Contract genuinely for fixed task/period, no permanent work available
Note: Can be redundancy or SOSR depending on circumstances
14. End of Secondment
Scenario: You were seconded to another department; secondment ends; no role to return to.
SOSR grounds: Temporary arrangement ending
Likely outcome: Should usually be redundancy rather than SOSR
Fair if: Genuinely no role available and fair selection process
15. Insistence on Working for Competitor
Scenario: You want to keep second job working for competitor; employer says it's incompatible.
SOSR grounds: Conflict of interest; breach of fidelity
Likely fair if: Genuine conflict exists, you were warned, refused to choose
Key: Usually handled as misconduct, but can be SOSR if not deliberate breach
16. Parole Conditions Prevent Work
Scenario: Released from prison but parole conditions prevent working with children/vulnerable people; this is your job.
SOSR grounds: Unable to perform role due to legal restrictions
Likely fair if: Restriction genuine, no alternative role available
17. Immigration Status Changes
Scenario: You lose right to work in UK (not employer's fault); visa refused/expires.
SOSR grounds: Illegality of continued employment
Likely outcome: Usually "illegality" rather than SOSR, but sometimes SOSR if grey area
Automatically fair: Continuing employment would be illegal
18. Business Sale Falls Through
Scenario: Business planned to sell; you were going to transfer; sale collapses; now too many staff.
SOSR grounds: Anticipated transfer not happening
Likely outcome: Usually redundancy rather than SOSR
Fair if: Genuine redundancy situation, fair selection
19. Pressure from Workforce
Scenario: Other employees threaten to strike/resign if you continue working there.
SOSR grounds: Maintaining workplace harmony
Usually unfair: Tribunals rarely accept peer pressure as sufficient reason
Red flag: Suggests possible discrimination or bullying
20. Reasonable Changes to Contract Terms
Scenario: Employer needs to change contract terms (e.g., reduce pay due to financial difficulties); you refuse.
SOSR grounds: Business need for contract variation
Likely outcome: Depends on reasonableness of changes and consultation
Fair if: Genuine business need, proper consultation, changes reasonable, dismissal proportionate
What Is SOSR?
The Legal Basis
Section 98(1)(b) of the Employment Rights Act 1996 provides that dismissal may be fair for:
"some other substantial reason of a kind such as to justify the dismissal of an employee holding the position which the employee held"
What "Substantial" Means
The reason must be:
- Genuine - not a pretext for something else
- Substantial - not trivial or minor
- Sufficient - enough to justify dismissal
- Related to the employment - relevant to the job
Common SOSR Situations
Business Reorganisation
| Scenario | SOSR Grounds |
|---|---|
| New shift patterns needed | Business need for change |
| Changing terms and conditions | Operational requirements |
| Restructure without redundancies | Reorganising work |
| Harmonising contracts | Post-merger integration |
Third-Party Pressure
Where third party demands dismissal:
- Customer refuses to work with employee
- Client contract requires specific staff
- Regulatory body concerns
- Loss of security clearance
Breakdown of Working Relationships
When relationship has irretrievably broken down:
- Personality clash (if severe)
- Loss of trust (not misconduct-related)
- Team dysfunction
- Relationship with key client
Other Examples
- Expiry of fixed-term contract for genuine fixed task
- Imprisonment (if not misconduct)
- Transfer refusal in genuine TUPE situation
- Business sale where no buyer found
- End of secondment
What SOSR Is NOT For
Not a Catch-All
SOSR should not be used when:
- The real reason is something else
- It's actually redundancy
- It's actually capability
- It's actually misconduct
- The employer just wants to get rid of someone
Red Flags for Tribunals
| Warning Sign | What It Suggests |
|---|---|
| Vague reason given | No substantial reason |
| Story keeps changing | Pretext for something else |
| No business need shown | Not genuine |
| Proper category available | Wrong reason used |
| Discrimination indicators | Unlawful motive |
Fair Process for SOSR
Investigation
Employer should:
- Establish the facts
- Consider whether SOSR is the right category
- Document the business need
- Consider impact on employee
Consultation
Before dismissing:
- Meet with employee
- Explain the situation fully
- Consider their response
- Explore alternatives
The Test
Tribunal asks:
- Is there a genuine reason that qualifies as SOSR?
- Did the employer follow fair procedure?
- Was dismissal within the range of reasonable responses?
Business Reorganisation SOSR
When It Applies
Where employer needs to change terms but:
- No redundancy (role continues)
- Employee won't agree to change
- Business need is genuine
Process Requirements
- Identify genuine business need
- Consult with affected employees
- Try to reach agreement
- Consider alternatives
- Warn of consequences of refusal
- Dismiss if no agreement, immediately re-engage on new terms
"Fire and Rehire"
This practice involves:
- Dismissing employees who refuse new terms
- Immediately offering re-engagement on new terms
Now subject to statutory code - employers must:
- Consult meaningfully
- Consider alternatives
- Not use dismissal as first resort
- Follow proper process
Third-Party Pressure
When It's Substantial
Third-party pressure may justify SOSR if:
- Pressure is genuine and serious
- Would result in substantial detriment to business
- Employer has properly investigated
- No reasonable alternative exists
Employer Must Still
- Investigate the situation
- Consider whether pressure is justified
- Look at employee's position
- Explore alternatives
- Follow fair process
Not Automatic
Employer cannot simply:
- Accept client's word without question
- Dismiss immediately on request
- Ignore employee's rights
Breakdown of Trust
When It Qualifies
Irretrievable breakdown may be SOSR if:
- Relationship genuinely can't continue
- Not the employee's fault (or conduct would apply)
- Employer has tried to resolve
- No alternative like transfer
Proving Breakdown
Evidence might include:
- Failed mediation attempts
- Impact on team performance
- History of difficulties
- Business impact
Not Just "We Don't Get On"
Personality differences alone insufficient:
- Must affect work significantly
- Genuine attempts to resolve needed
- Consider whose "fault" it is
- Look at alternatives
Employee Rights
Procedural Fairness
Even with genuine SOSR:
- Must be consulted
- Must have chance to respond
- Should receive written reasons
- Can be accompanied at meetings
- Has right to appeal
Challenge Options
If dismissed for SOSR, you can:
- Appeal internally
- Claim unfair dismissal (if 2 years' service)
- Challenge whether reason was genuine
- Challenge reasonableness of dismissal
What Tribunal Examines
- Was the reason genuinely substantial?
- Was it properly investigated?
- Was the employee consulted?
- Were alternatives considered?
- Was dismissal within reasonable range?
Compensation
Standard Unfair Dismissal
If SOSR dismissal is found unfair:
- Basic award (based on service)
- Compensatory award (actual losses)
- Subject to statutory cap
No Enhanced Award
Unlike automatically unfair dismissals:
- No enhanced protection
- Standard compensation rules apply
- No interim relief available
Challenging SOSR Dismissal
Grounds for Challenge
| Argument | How to Make It |
|---|---|
| Not substantial | Reason is too trivial |
| Not genuine | Real reason is different |
| No consultation | Wasn't given fair hearing |
| Alternatives existed | Could have done something else |
| Unreasonable | Dismissal too harsh |
Evidence to Gather
- Business documents showing (or not showing) need
- Correspondence about the decision
- Notes from meetings
- Evidence of alternatives not considered
- Comparator evidence
Tips for Employees

- Ask for specifics - what exactly is the reason?
- Request evidence - why is this substantial?
- Propose alternatives - what else could be done?
- Challenge the process - has it been fair?
- Get advice - is this genuine SOSR?
- Know your rights - you can still claim unfair dismissal
