Continuous employment and employee rights

Continuous employment usually means working for the same employer without a break, or with short breaks that don't interrupt the continuity of employment. These breaks may include time out of service due to strikes, lock-outs, and even unfair dismissal, where the employee is reinstated or re-engaged into the service.

Employment can sometimes also be treated as continuous if your employee has previously been with a different employer, for example, following the transfer of a business or undertaking. See responsibilities to employees if you buy or sell a business.

When does continuous employment begin and end?

To work out how long an employee has been continuously employed, you should first establish the date on which they qualify for a particular right - their qualification date - for the entitlement in question. The qualification date is defined differently for each entitlement.

See a table showing minimum periods of continuous employment and qualification dates for employment rights.

Once you have established the qualification date, you should count back from that date to the date of their first day of work with you.

However, remember that time with a previous employer can sometimes be added to the time with a present employer - see the effect a change of employer has on continuous employment.

Within the period of continuous employment, there may be:

• breaks in employment that don't break the continuity of employment
• periods that don't count towards the total length of continuous employment, but also don't break continuity

See continuous employment and breaks in work.

An industrial tribunal can settle any dispute about the length of an employee's continuous service. Generally, the tribunal will assume the employment was continuous until it is shown otherwise.

Notice periods and continuous employment

The 'effective date of termination' - for the purpose of calculating the length of service - is the date on which employment ends following the notice period. If you do not give an employee any notice, the effective date of termination will be the date on which that statutory notice would have expired if you had given them notice.

See issue the correct periods of notice.

To find out whether an employee's full-service period - from the start of their employment to the qualification date - has been continuous and whether it all counts, you must consider it week by week.

For this purpose, a week is a period of seven days ending on a Saturday. If at any point continuity has been broken, the weeks before the most recent break will not count towards the employee's continuous employment.

A week normally counts towards a period of continuous employment if, in that week, the employee actually works or the employee's relations with the employer are governed by a contract of employment.

Absence from work because of sickness, maternity, paternity, adoption, and parental leave, temporary lay-off and annual leave all count towards continuous employment automatically, provided the contract continues throughout.

Industrial action

If an employee takes part in a strike, you should treat their starting date as postponed by the number of days between the last working day before the employee was on strike and the day on which they resumed work.

The starting date is not, however, postponed by periods of lockout, ie, where the employer prevents employees from entering the workplace.

The employee's period on strike does not break the continuity of employment, except in some circumstances where the employer dismisses the employee during the strike.

Employment overseas

Service abroad generally counts towards continuous employment. In determining rights to a statutory redundancy payment, a week of this service only counts if the employee was classed as an employed earner during that week.

An 'employed earner' is someone for whom you pay Class 1 National Insurance contributions (NICs) - or for whom you would pay Class 1 NICs if they earned above the lower earnings threshold. Rates and thresholds for employers 2025 to 2026.

Military service

If you employ a member of the volunteer reserve forces who is returning from a period of military service, you must reinstate them in their old job or a similar position.

If you terminate a person's employment solely or mainly because of their liability to be mobilised for military service, you will be committing an offense, and a court can order you to pay compensation as well as levying a fine.

See if a Reservist employee is called up for service.

Weeks when there is no contract

Weeks during which an employee has no contract of employment may count towards continuous employment and will not break the continuity of employment, if one of the following occurs:

• work ceases temporarily
• an employee is away from work sick or injured and is then re-engaged within 26 weeks of the contract being terminated
• the employee is away in circumstances in which their employment is regarded as continuing for some purposes, by arrangement or custom

Employees must meet qualification criteria to receive certain statutory payments, namely:

• statutory redundancy pay (SRP)
• statutory maternity pay (SMP)
• statutory paternity pay (SPP)
• statutory adoption pay (SAP)
• statutory shared parental pay (ShPP)
• statutory parental bereavement pay (SPBP)

Continuous service for SRP

Redundant employees have a number of rights, the main one being the right to receive SRP. In order to qualify for SRP, they must have at least two years of continuous service.

Employment may be treated as continuous for redundancy pay purposes if, for example, an individual is employed by a specified local government employer and moves to another specified employer within Northern Ireland. Similar legislative provisions operate in Great Britain, but there is currently no reciprocal arrangement between Great Britain and Northern Ireland.

Continuous service is counted backward from the 'relevant date' - usually the date the notice you give to your employee expires. If you give less than the legal minimum notice, the extra notice you should have given is added on.

SRP is based on an employee's amount of continuous service, up to a maximum of 20 years. Certain absences - eg, sickness or lay-offs - can count towards continuous service even if the contract of employment was suspended. See continuous employment and breaks in work.

When working out continuous service for SRP, you should deduct any strike days from the total length of service. Note that going on strike does not actually break the continuity of employment.

If an employee is made redundant and is due to start another job (under a new employment contract) with the same employer, then continuity of employment will be preserved so long as they start their new job within four weeks of the effective date of termination of their previous employment contract. Note that the offer to start the new job with the same employer must be made prior to the dismissal taking effect.

Continuous service for SMP, SPP, SAP, ShPP, and SPBP

For more on the continuous service requirements for these payments, see our guidance on:

• Maternity leave and pay
• Paternity leave and pay
• Adoption leave and pay
• Shared parental leave and pay
• Parental Bereavement Leave and Pay

If you reinstate or re-engage an employee who has complained of unfair dismissal, the weeks between the dismissal taking effect and the resumption of work will count towards continuous employment. It works as though there had never been a dismissal, and continuity of employment is maintained.

However, the reinstatement or re-engagement must arise from one of the following:

• an order of a tribunal that has found the dismissal unfair
• a claim made under a dismissals procedure designated by the Department for the Economy (DfE)
• an agreement reached with the help of a Labour Relations Agency (LRA) conciliator or the LRA arbitration scheme
• a compromise agreement under the relevant legislation
• an applicable statutory dispute resolution procedure

See dismissing employees.

Reinstating military reservists

After a reservist has been mobilised, you must reinstate that employee in their old job on their return from service, provided that:

• the reservist applies for reinstatement in due time
• your business continues unchanged

If you cannot reinstate the reservist in their original role, you must offer a suitable alternative position with the same terms and conditions of service.

See if a Reservist employee is called up for service.

Normally, when an employee changes employers, this breaks continuity, and their continuous employment must begin again.

However, continuous employment is preserved if:

• under an Act of Parliament or the Northern Ireland Assembly, one corporate body takes over from another as the employer
• the employer dies, and their personal representatives or trustees keep the employee on
• there is a change in the partners, personal representatives, or trustees who employ the employee
• the employee moves from one employer to another when, at the time of the move, the two employers are associated employers
• the employee of a health service employer moves to another health service employer while undergoing training

Continuous employment is also preserved when a business or an undertaking, or part of a business, is transferred from one employer to another. Continuity will also be preserved where there is a service provision change, such as a service previously undertaken by an employer being awarded to another contractor.

See responsibilities to employees if you buy or sell a business.

The following table sets out the minimum periods of continuous employment an employee needs to qualify for certain statutory employment rights. It also gives the relevant date on which an employee qualifies for that right.

Note that any statutory employment rights not listed here have no minimum service requirement. For example, an employee has the right to take statutory maternity leave or paid annual leave from day one of their employment.
