Role Details
Role: Employee Relations Specialist
Location: 5 days a week – London, White City
Reports to: Head of HR, UK
About the Role
We're looking for an Employee Relations Specialist to join our UK People team. This is a hands-on, high-judgement role supporting Flatpay's continued growth with a clear focus on ER case management, employment law application, and people risk - from probationary matters and sickness absence through to grievances, right to work compliance, data governance, and settlement negotiations.
You'll be a trusted first point of contact for managers across the UK business, bringing the legal rigour and commercial judgement to navigate complex people situations confidently and correctly.
Responsibilities
Case management & employment law
- Own and manage a varied caseload of ER matters end-to-end: performance, absence, conduct, probationary reviews, and dismissals
- Advise managers and leaders on legally sound approaches, balancing commercial pace with employment law compliance
- Draft outcome letters, PIPs, settlement agreements, and correspondence to a high standard — clear, human, and legally precise
- Manage protected conversations and settlement negotiations, including preparing documentation and coordinating with external solicitors
- Support on Equality Act considerations, including reasonable adjustments during absence and performance processes
Grievances
- Manage formal and informal grievance processes end-to-end, advising on the appropriate route and ensuring consistent application of policy
- Support or conduct grievance investigations where required, including scoping, interviewing, and producing well-reasoned outcome letters
- Advise on grievances that overlap with other ER matters — discrimination, harassment, or whistleblowing — and escalate appropriately
- Coach managers on handling informal concerns before they escalate to formal grievance
Probation & early-stage performance
- Support managers in handling probationary reviews where performance, conduct, or attendance is a concern
- Advise on the correct process for extending or terminating probation, ensuring decisions are well-documented and legally defensible
- Draft probationary outcome letters and ensure accurate, timely communication to employees, including correct notice periods and final pay
- Handle post-termination queries from former probationary employees, including payroll discrepancies or disputed process steps
- Flag where Equality Act considerations may affect the approach
Right to work & immigration compliance
- Advise on right to work cases where additional scrutiny is required, including flagged documents, complex visa types, or unclear eligibility
- Support the TA team with the correct approach where a candidate or employee's right to work status raises a legal question
- Liaise with Legal or immigration advisors where sponsored workers or more complex immigration situations arise
- Ensure advice given is consistent, well-documented, and aligned with current Home Office guidance
Manager coaching & capability building
- Act as a trusted first point of contact for managers navigating people issues — helping them handle situations correctly and with confidence
- Coach managers through live ER cases, building their capability to handle similar situations independently in future
- Identify patterns in case types or management behaviours that point to a broader training or process need
- Support the development of practical manager guidance, toolkits, and templates that make good ER practice easier to apply day-to-day
Data compliance & information governance
- Respond to and manage suspected data breaches involving employees or former employees, coordinating with Legal and ICO reporting obligations as required
- Maintain accurate employee records and ensure ER case documentation meets GDPR standards
- Handle third-party correspondence involving employee data (e.g. DWP/DEA notices, court orders, statutory bodies)
Broader people operations
- Support the Head of HR UK on policy development, handbook updates, and UK-specific employment frameworks
- Partner with cross-functional stakeholders including Finance, Legal, and commercial leadership
Skills & Attributes
- High judgement and confident handling complex ER cases end-to-end with appropriate levels of autonomy
- Strong working knowledge of UK employment law and HR best practice
- Able to draft clearly and precisely — outcome letters, PIPs, and settlement agreements that are legally sound and human in tone
- Commercially minded — understands the business context behind HR decisions and communicates in those terms
- Strong communicator: direct without being blunt, empathetic without being vague
- Organised and delivery-focused, able to manage a busy caseload without losing attention to detail
- Comfortable working in a fast-moving, scaling business where processes are still being built
