Probationary Periods: Employer's Guide
How to use probationary periods effectively. Setting length, reviews, extending probation, and dismissing during probation without unfair dismissal risk.
Probationary periods help you assess new employees before confirming them in post. Using them properly protects both employer and employee.
What Is a Probationary Period?
A probationary period is an initial period of employment where:
- The employer assesses the employee's suitability
- Either party can usually end employment with shorter notice
- At the end, the employee is confirmed in post or dismissed
Important: Probation is a contractual arrangement, not a legal status. The employee still has employment rights from day one.
Setting Up Probation
Length
Common probation lengths:
- 3 months - Standard for straightforward roles
- 6 months - Common for professional/complex roles
- 12 months - Sometimes used for very senior roles
Considerations:
- How long to properly assess the role?
- Nature of the work
- Training requirements
- Industry norms
Contractual Terms
Your contract should specify:
1. Length of probation period
2. Notice period during probation
3. What happens at the end (confirmation or dismissal)
4. Whether probation can be extended
5. That normal terms apply after successful completion
Example Clause
"Your employment is subject to a probationary period of 3 months. During this time, either party may terminate employment by giving one week's notice. At the end of the probationary period, subject to satisfactory performance and conduct, your employment will be confirmed and the notice period will increase to one month."
During Probation
Setting Expectations
At the start:
- Explain job requirements clearly
- Set specific objectives
- Provide necessary training
- Assign a buddy or mentor
- Schedule regular check-ins
Regular Reviews
Don't wait until the end to review:
| Week | Review Focus |
|---|---|
| Week 1-2 | Settling in, initial impressions |
| Month 1 | Progress against objectives |
| Month 2 | Performance, areas for development |
| Before end | Final assessment, decision |
Documentation
Keep records of:
- Objectives set
- Feedback given
- Training provided
- Performance issues raised
- Employee's response
- Review meeting notes
Ending Probation Successfully
Confirming in Post
When probation ends successfully:
- Hold a review meeting
- Confirm satisfactory completion
- Put it in writing
- Confirm any changes (notice period, benefits)
- Update personnel records
Confirmation Letter
"I am pleased to confirm that you have successfully completed your probationary period. Your employment is now confirmed on the standard terms set out in your contract. Your notice period is now [X weeks/months]."
Extending Probation
When to Extend
Consider extension when:
- Progress is being made but employee needs more time
- External factors affected assessment (illness, reduced workload)
- You want to be fair but aren't confident enough to confirm
- Specific concerns need more time to resolve
How to Extend
- Check contract allows extension
- Meet with employee before probation ends
- Explain reasons clearly
- Set new objectives/expectations
- Confirm new end date
- Put everything in writing
- Schedule review meetings
Extension Letter
"Following our meeting on [date], I am writing to confirm that your probationary period will be extended by [X weeks/months] until [date].
The reasons for this extension are: [specific reasons]
During this extended period, we expect to see: [specific improvements/objectives]
We will meet on [dates] to review your progress.
If there are any areas where you need additional support, please let me know."
Limits on Extension
- Don't extend indefinitely
- One extension is normal, two is concerning
- Total probation shouldn't be excessive for the role
- Each extension should have clear purpose
Dismissal During Probation
Legal Position
Employees in probation have fewer protections:
- Under 2 years' service: Cannot claim ordinary unfair dismissal
- Any service length: Can claim automatically unfair dismissal or discrimination
Automatically unfair reasons include:
- Pregnancy/maternity
- Whistleblowing
- Health and safety complaints
- Asserting statutory rights
- Trade union activities
Fair Process Still Matters
Even though unfair dismissal risk is lower:
- Follow a fair process
- Document your reasons
- Give the employee chance to respond
- Protects against discrimination claims
- Good practice and fair treatment
Steps to Dismiss During Probation
- Identify the issue - Performance, conduct, capability?
- Have you addressed it? - Feedback, support, warnings?
- Document everything - What happened, when, your actions
- Meet with the employee - Explain concerns, hear their response
- Make decision - Confirm or dismiss
- Write confirming dismissal - Reasons, end date, any notice
Notice During Probation
Check the contract. Common arrangements:
- 1 week notice during probation
- Can be less if contract specifies
- Can pay in lieu if allowed
Dismissal Letter (Probation)
"Following our meeting on [date], I write to confirm that your employment will end on [date]. This is within your probationary period.
The reasons for this decision are: [specific reasons]
You will receive [notice period] notice / payment in lieu of notice.
[Details of final pay, return of property, etc.]"
Common Probation Issues
Poor Performance
What to do:
- Give clear feedback early
- Provide support/training
- Set improvement targets
- Review progress regularly
- Dismiss if no improvement
Don't:
- Wait until end of probation to raise issues
- Spring dismissal without warning
- Fail to document
Conduct Issues
Minor misconduct during probation:
- Address informally first
- Follow disciplinary procedure for serious issues
- Gross misconduct can still justify summary dismissal
Sickness During Probation
You can dismiss for poor attendance during probation, but:
- Be cautious of disability discrimination
- Pregnancy-related absence must be disregarded
- Consider reasons for absence
- Document fairly
Employee Doesn't Fit Culture
Legitimate concern but:
- Be specific about what's not working
- "Fit" shouldn't mask discrimination
- Give feedback on behaviours, not personality
- Document objectively
After the 2-Year Mark
Why 2 Years Matters
After 2 years' continuous service:
- Employee can claim ordinary unfair dismissal
- Need fair reason AND fair procedure
- More protection for the employee
Probation and the 2-Year Qualifying Period
Probation typically ends well before 2 years. But:
- Probation doesn't reset the clock
- Service counts continuously from day one
- After 2 years, same dismissal rules regardless of when probation ended
Best Practices
For Employers
- Use probation for its purpose - Actually assess suitability
- Set clear expectations - From day one
- Review regularly - Don't wait until the end
- Give feedback - Both positive and developmental

Frequently Asked Questions
- Can I dismiss someone during their probation period?
- Yes, and with less risk than after the probationary period. However, you should still follow a fair process. Employees with less than 2 years' service generally cannot claim ordinary unfair dismissal, but can claim for automatically unfair reasons or discrimination.
- How long should a probation period be?
- Typically 3-6 months. It should be long enough to properly assess the employee but not so long that it feels excessive. The nature of the role matters - complex roles may need longer.
- Can I extend a probation period?
- Yes, if the contract allows it. Extensions are useful when you need more time to assess but aren't ready to confirm or dismiss. Clearly communicate the reasons and new review date.
