85. HR Policy: Contract Changes & Continuity of Employment
85.1. The purpose of this policy is to define how Architecture North Ltd manages changes to employee contracts while maintaining legal compliance, transparent record-keeping, and the protection of continuous employment rights.
85.1.1. This policy ensures clarity, fairness, and consistency across all contract amendments, regardless of employment type.
85.2. This policy applies to all individuals engaged by Architecture North Ltd under any form of contract, including but not limited to:
Permanent Full-Time
Permanent Part-Time
Fixed-Term Contracts
Zero-Hours Contracts
Casual Workers
Apprentices
Interns
Work Experience
Agency Workers
Temporary Workers
Freelancers / Self-Employed
Consultants
Seasonal Workers
Volunteers
85.3. Continuous employment refers to the unbroken period an individual has been engaged by Architecture North Ltd, regardless of any changes to the terms or type of contract.
85.3.1. Under UK employment law, changing the terms of a contract does not reset continuous service unless the employment relationship is legally terminated.
85.3.2. Employees retain all statutory rights linked to their start date, including but not limited to:
Redundancy rights
Notice periods
Holiday entitlement
Maternity/paternity/adoption rights
Protection from unfair dismissal (after qualifying period)
Pension continuity
Continuous service for pay and benefits
85.4. A contract change (also referred to as a Contract Variation) may include:
Change of role or duties
Change from full-time to part-time (or vice versa)
Change from permanent to zero-hours
Change in pay or hours
Change in working location
Change of contract type (e.g., Casual → Permanent)
85.4.1. Contract changes:
Do not create a new employment period
Do not reset the start date
Do not justify issuing a new Employee ID
Do not break continuity of service
85.4.1. Even if the contract type changes significantly (e.g., Permanent Full-Time → Zero Hours), the employment remains a continuous relationship.
85.5. Architecture North ltd uses a structured Employee Identification Numbering System.
85.5.1. Once assigned, an Employee ID:
Remains permanently linked to the individual
Reflects their onboarding year and contract type at the time of joining
Is not updated or replaced when the contract changes
85.5.1.1 This permanent identifier is essential for:
Payroll and HMRC records
Legal audit trails
Pension and benefits tracking
Accurate HR history
85.5.1.2. Example:
An employee hired in 2021 on a Permanent Full-Time contract (ID: 21EMP01AN) who moves to a Zero-Hours contract in 2023 retains the same ID.
85.6. When an employee’s contract is altered, the following process must be followed:
85.6.1. A contract change may be:
Requested by the employee
Proposed by the business
Required due to business needs
Mandated by law or compliance
85.6.2. Where appropriate, a discussion must take place between:
The employee
The line manager
HR (or responsible administrative authority)
85.6.3. All contract changes must be formally documented through:
A Contract Variation Letter, or
A New Contract Agreement (where terms undergo major restructuring)
85.6.3.1. The document must state:
Original employment start date
Original contract type
New contract type
Effective change date
Updated terms
Confirmed protection of continuity of employment
85.6.4. The employee must sign and return the variation document before changes take effect (except where statutory changes apply).
85.6.5. HR must update:
Contract type field
Pay and hour settings
Working pattern
Payroll classifications
Personnel file documentation
Any relevant system access or permissions
85.6.5.1. The Employee ID remains unchanged.
85.7. Architecture North Ltd maintains accurate records for a minimum of 6 years (or longer where legally required), including:
Original employment contract
All variation letters
Emails confirming consultation
Updated job descriptions
Updated pay information
System logs reflecting the change
Payroll submission evidence
85.7.1. Records must be stored securely in accordance with GDPR principles.
85.8. The following actions are prohibited under this policy:
Issuing a new Employee ID to reflect a contract change
Resetting an employee’s start date
Treating a contract change as a termination and re-hire (unless legally required)
Removing past records that relate to original terms
Misrepresenting an employee’s continuity of employment
85.8.1. These actions may breach UK employment law and create risk for both the employee and the company.
85.9. This policy will be reviewed annually or earlier where:
Legislation changes
Company structure evolves
New contract types are introduced
Audit or compliance feedback requires updates
