Continuous employment is the backbone of most employment rights. Knowing how it is calculated — and what can and cannot break it — protects you from losing rights you have earned.
Why Continuous Employment Matters: Key Thresholds
| Continuous service | Rights unlocked |
|---|---|
| From day one | Minimum wage, holiday pay, SSP, discrimination protection, whistleblowing protection, flexible working request |
| 1 month | 1 week statutory notice |
| 2 years | Unfair dismissal; statutory redundancy pay |
| Per year | Each additional year adds to redundancy pay entitlement (capped at 20 years) |
What Preserves Continuity
| Event | Continuity preserved? |
|---|---|
| Sickness or injury absence | Yes |
| Maternity, paternity, adoption, parental leave | Yes |
| Temporary lay-off or short-time working | Yes (if expected to return) |
| Agreed career break | Yes — if employer agrees in writing |
| TUPE business transfer | Yes — statutory preservation |
| Industrial action | Continuity not broken (but days count differently) |
What Can Break Continuity
| Event | Continuity broken? |
|---|---|
| Resignation followed by new employment with same employer (with gap) | Possibly — depends on gap length |
| Dismissal and re-engagement (with a gap) | Often yes — each case assessed |
| Change of employer without TUPE | Usually yes |
| Zero-hours contract with extended period of no work | Depends — courts look at the nature of the arrangement |
Checking Your Start Date
Your start date is the date your employment contract began — check your contract, P45, or payslips. If you were transferred under TUPE, your TUPE start date is your original start date with the transferring employer.
What Breaks Continuous Employment?
Not all gaps in employment break continuity. ACAS guidance and the Employment Rights Act 1996 preserve continuous employment in specific circumstances:
| Situation | Continuity preserved? |
|---|---|
| Working for a different employer after TUPE transfer | Yes |
| Lay-off or short-time working | Yes |
| Strike or lock-out | Yes |
| Illness, injury, maternity/adoption/paternity leave | Yes |
| Temporary absence by agreement | Yes |
| Agency worker transferred to permanent role with same hirer | Sometimes — depends on arrangement |
| Voluntary resignation, re-hired by same employer | Generally NO — new continuous service period begins |
One exception: if you resign and are rehired within 4 weeks under a new contract to do similar work, the gap may not break continuity — but this is fact-specific and worth checking with ACAS or a solicitor.
Practical importance: Continuous employment determines when you qualify for unfair dismissal rights (2 years), statutory redundancy pay (2 years), statutory notice (1 month), and statutory parental rights (some are day-one rights).
