General Principles
"Without Unreasonable Delay"

- Progressed promptly
- Not unnecessarily prolonged
- Completed in reasonable time
- Balanced with thoroughness
Why Timing Matters
| Reason | Impact |
|---|---|
| Fairness | Employee left in limbo |
| Memory | Evidence becomes stale |
| Anxiety | Prolonged stress |
| Business | Disruption continues |
| Legal | May affect tribunal claim |
Investigation Timescales
Typical Durations
| Complexity | Reasonable Time |
|---|---|
| Simple matter | Days to 1-2 weeks |
| Moderate complexity | 2-4 weeks |
| Complex case | 4-8 weeks |
| Very complex | Could be longer |
Factors Affecting Duration
| Factor | Impact |
|---|---|
| Number of witnesses | More interviews take time |
| Document volume | Review takes longer |
| Availability | Scheduling challenges |
| External input | May need to wait |
| Complexity | More analysis needed |
What's Unreasonable
- Unexplained delays
- Long gaps between steps
- No progress for weeks
- Not prioritised appropriately
- Dragging on for months without justification
Notification to Hearing
Reasonable Notice
Employee should receive:
| Element | Typical Timeframe |
|---|---|
| Written notification | Sent promptly after investigation |
| Allegations detailed | With notification letter |
| Evidence provided | At least 5 working days before |
| Hearing date | At least 5 working days notice |
Why Notice Matters
- Time to prepare response
- Arrange companion
- Gather evidence
- Take advice
- Mental preparation
Postponement Requests
Employee may request if:
- Insufficient notice
- Companion unavailable
- Need more time (reasonable)
- Illness or emergency
Employer should agree to one postponement (up to 5 working days for companion issues).
Hearing to Decision
Decision Timing
| Approach | Typical Time |
|---|---|
| Same day (after adjournment) | Often possible for simple cases |
| Next day | Common |
| Within 2-3 days | Reasonable for complex |
| Week+ | May need justification |
Why Not Instant
Don't decide at the table:
- Need time to consider
- Shows proper thought
- Allows checking
- More defensible
Communication

|---|---|
| Verbal outcome | Usually same day or next |
| Written confirmation | Within 5 working days |
| Right to appeal | In outcome letter |

Lodging Appeal
| Aspect | Typical Requirement |

Final Decision
Appeal outcome should be:

Employee's Position
If Process Delayed
You can:
- Ask for updates
- Request timeline
- Raise concern formally
- Seek advice
- Document delays
What to Write
"I am concerned about the delay in progressing this disciplinary matter. It has now been [X weeks/months] since [date]. Please provide an update on the timeline and when I can expect resolution."
Grievance About Delay
Consider if:
- Very lengthy delay
- No explanation given
- Causing significant impact
- May strengthen any claim
But be aware: may complicate matters.
When Delay Is Justified
Acceptable Reasons
| Reason | Why Acceptable |
|---|---|
| Police investigation | May need to wait |
| Complex fraud | Forensic analysis |
| Key witness unavailable | Illness, holiday |
| Employee absence | Sick, parental leave |
| External input needed | Expert reports |
Must Still Progress
Even with justified delay:
- Other steps should continue
- Updates should be given
- Review should happen
- Shouldn't drift indefinitely
Time Limits After Incident
Discovery vs Occurrence
Time runs from when employer:
- Became aware of issue
- Should reasonably have known
- Not necessarily when incident occurred
Old Matters
| Situation | Consideration |
|---|---|
| Recently discovered | May still proceed |
| Long known, no action | May be too late |
| Pattern now clear | Can consider history |
| Evidence still exists | More viable |
Fairness Considerations
Tribunal considers:
- Why delayed?
- Prejudice to employee
- Evidence still available
- Memory issues
- Employee's expectations
