SSP and Multiple Sickness Periods: Linking Rules Explained

Employees with recurring health conditions or multiple unrelated illnesses can accumulate several periods of sickness. Understanding how these periods interact is essential for calculating SSP correctly.

The Linking Rule

When Periods Link

Periods of Incapacity for Work (PIWs) link together if they are separated by 8 weeks or less.

Result: They're treated as one continuous period for SSP purposes.

When Periods Don't Link

If an employee is well for more than 8 weeks, the periods don't link.

Result: SSP entitlement resets to a fresh 28-week maximum.

Practical Examples

Example 1: Short Gaps Between Illnesses

Scenario:

• Employee off sick: 10 days (flu)
• Returns to work: 5 weeks
• Off sick again: 7 days (back injury)

Analysis: The gap is only 5 weeks, so the periods link.

SSP calculation:

• First absence: 7 days SSP (after 3 waiting days)
• Second absence: 7 days SSP (no waiting days applied again)
• Total SSP used: 14 days out of 28 weeks

Example 2: Gap Exceeds 8 Weeks

Scenario:

• Employee off sick: 15 days (surgery recovery)
• Returns to work: 10 weeks
• Off sick again: 5 days (cold)

Analysis: The gap is 10 weeks, so periods don't link.

SSP calculation:

• First absence: 12 days SSP (after 3 waiting days)
• SSP entitlement resets
• Second absence: 2 days SSP (3 waiting days apply again)

Example 3: Using Up Entitlement Across Linked Periods

Scenario:

• Employee off sick: 20 weeks (serious illness)
• Returns to work: 4 weeks
• Off sick again: 10 weeks (relapse)

Analysis: Gap is only 4 weeks, so periods link. Total absence = 30 weeks.

SSP calculation:

• First absence: 20 weeks SSP
• Second absence: 8 weeks SSP (to reach 28-week maximum)
• Remaining 2 weeks: No SSP due

Action: Issue form SSP1 when entitlement exhausted. Employee can claim ESA.

Waiting Days and Linking

First Period of Sickness

The first 3 qualifying days are waiting days. SSP is paid from day 4 onwards.

Linked Periods

No new waiting days apply. The employee continues from where they left off in their SSP entitlement.

Non-Linked Periods

If the gap exceeds 8 weeks, the entitlement resets and new waiting days apply.

Calculating the 8-Week Gap

What Counts as the Gap?

Count calendar days from:

• Last day of sickness in the first period
• To first day of sickness in the next period

Including Weekends and Non-Working Days

Yes. All calendar days count, not just working days.

8 weeks = 56 days

Example Calculation

First period ends: Monday 1 January Second period starts: Friday 1 March

Days between: 59 days

Result: Periods don't link (gap exceeds 56 days)

Tracking Multiple Employees

Records You Must Keep

For each employee:

• Start and end date of each PIW
• Days of SSP paid
• Days of SSP remaining (out of 28 weeks)
• Whether periods linked or not

Keep records for at least 3 years after the tax year they relate to.

Software and Payroll

Most payroll software tracks SSP automatically. Ensure it correctly applies:

• Linking rules
• Waiting day logic
• 28-week maximum

Double-check calculations for employees with frequent absences.

The 28-Week Maximum

How It Works

SSP is available for a maximum of 28 weeks (196 days) in any linked period of sickness.

What Happens After 28 Weeks?

Once the 28-week limit is reached:

1. Stop paying SSP
2. Give the employee form SSP1
3. Employee may claim Employment and Support Allowance (ESA) or Universal Credit

Does the Clock Ever Reset?

Yes, if the employee is well for more than 8 weeks, the 28-week entitlement resets when a new unlinked period begins.

Different Illnesses vs Same Condition

Does the Cause Matter?

No. Linking rules apply regardless of whether the absences are for the same or different illnesses.

Example:

• Week 1: Broken leg
• Gap: 6 weeks
• Week 2: Stomach bug

Periods link even though illnesses are unrelated.

Part-Time Workers and Linking

Qualifying Days

SSP is only paid on qualifying days (days the employee normally works).

Linking Rules Apply Equally

Part-time and full-time employees follow the same 8-week linking rule.

Example: A part-time worker (3 days/week) who's off sick twice with a 5-week gap will have linked periods, just like a full-time worker.

Occupational Sick Pay and Linking

Separate Rules May Apply

If your company offers enhanced sick pay above SSP, your scheme may have different rules about:

• Resetting entitlement
• Linking periods
• Maximum duration

Check your policy documents and contracts.

SSP Linking Still Applies

Even if your company scheme has different rules, you must still apply SSP linking rules for statutory entitlement.

Common Scenarios

Scenario: Chronic Condition with Flare-Ups

Employee has a long-term condition causing regular short absences (e.g., migraines, back pain).

Approach:

• Track each absence
• Apply linking rules
• Monitor total SSP used
• Consider workplace adjustments to reduce absences

Scenario: Winter Illnesses

Employee off with flu in November, then cold in January.

Approach:

• Check gap between last day of flu and first day of cold
• If less than 8 weeks, periods link
• No new waiting days

Scenario: Planned Surgery with Complications

Employee off for planned surgery (6 weeks), returns for 3 weeks, then off again due to surgical complications (4 weeks).

Approach:

• Periods link (gap only 3 weeks)
• Total SSP: 10 weeks used out of 28 weeks
• Continue tracking if further absences occur

When to Issue Form SSP1

You must give form SSP1 to an employee if:

• They've used all 28 weeks of SSP
• They don't qualify for SSP

Issue the form within 7 days of making the decision.

Impact on Other Entitlements

Annual Leave

Employees continue accruing annual leave during SSP. Some take accrued leave after long-term sickness.

Pension Contributions

Check your pension scheme rules. Some pause contributions during sick leave beyond a certain period.

Other Benefits

Contractual benefits usually continue during SSP periods unless stated otherwise.

Record-Keeping Template

For each employee, track:

Date Off	Date Return	Days Sick	Gap (Days)	Linked?	SSP Paid	SSP Remaining
1 Jan	10 Jan	10	-	-	7	189 days
5 Feb	12 Feb	8	26	Yes	8	181 days

Avoiding Mistakes

Mistake 1: Not Tracking Gaps

Issue: Paying new waiting days when periods should link.

Solution: Record all absence dates and calculate gaps.

Mistake 2: Ignoring 28-Week Limit

Issue: Continuing to pay SSP beyond 28 weeks in a linked period.

Solution: Monitor cumulative SSP paid. Set alerts when approaching 28 weeks.

Mistake 3: Linking When Shouldn't

Issue: Linking periods with gaps over 8 weeks.

Solution: Count calendar days carefully. 8 weeks = 56 days.

Mistake 4: Applying Waiting Days to Linked Periods

Issue: Deducting waiting days again when periods link.

Solution: Waiting days only apply to the first period in a linked sequence.

Support for Long-Term Sickness

If an employee is approaching 28 weeks:

• Have early conversations about return to work
• Consider phased returns
• Explore reasonable adjustments
• Occupational health referral
• Disability discrimination obligations

When SSP Ends Mid-Period

If an employee exhausts their 28-week entitlement during an ongoing absence:

• SSP stops immediately
• Issue form SSP1
• Employee claims ESA or Universal Credit
• They remain on unpaid sick leave or may be medically terminated (subject to process)
