Show Cause Letter (UK)

A Show Cause Letter in the United Kingdom records an employer decision affecting an employee's engagement and the reasons and procedure followed, with its requirements set by the Employment Rights Act 1996.

The Employment Rights Act 1996 is the primary statute governing employee rights in Great Britain. Section 94 of the Employment Rights Act 1996 grants employees with at least two years' qualifying service the right not to be unfairly dismissed. Section 98 sets out the test for fairness: the dismissal must be for a potentially fair reason (conduct, capability, redundancy, illegality, or some other substantial reason) and must be carried out through a fair procedure. A show cause letter forms part of the procedural fairness requirement by ensuring the employee has a documented opportunity to respond to allegations before any decision is made.

The Employment Tribunal adjudicates unfair dismissal claims under the Employment Rights Act 1996. Tribunals apply the band of reasonable responses test, assessing whether the employer's decision to dismiss and the procedure used fell within the range of responses a reasonable employer might have adopted. Failure to issue a show cause letter — or failure to give the employee adequate time to respond — can shift the tribunal's assessment toward a finding of procedural unfairness, which may result in a basic award and a compensatory award under Section 118 of the Employment Rights Act 1996.

The Advisory, Conciliation and Arbitration Service (ACAS) provides early conciliation under Section 18A of the Employment Tribunals Act 1996. Before lodging an Employment Tribunal claim, a claimant must contact ACAS for early conciliation. The ACAS Code of Practice on Disciplinary and Grievance Procedures recommends that employers carry out a reasonable investigation, notify the employee in writing of the alleged issue, hold a disciplinary meeting, allow the employee to be accompanied, and provide a right of appeal. A show cause letter addresses the notification step. The Information Commissioner's Office (ICO) regulates personal data held in disciplinary files under the UK GDPR and Data Protection Act 2018.

A Show Cause Letter in the United Kingdom is used whenever an employer has reasonable grounds to suspect that an employee has committed misconduct, is performing below the required standard, or has been absent from work without authorisation, and the employer wishes to give the employee a formal opportunity to respond before any disciplinary action is taken.

The letter is appropriate at the investigatory stage of a disciplinary process — after initial inquiries have identified a concern but before a formal disciplinary hearing is convened. Issuing a show cause letter before holding a disciplinary hearing aligns with the ACAS Code of Practice on Disciplinary and Grievance Procedures, which recommends that employers notify employees in writing of any allegations and give them sufficient time to prepare a response.

For conduct matters, a show cause letter is used where an employee is alleged to have breached workplace rules — for example, persistent lateness, unauthorised use of company assets, aggressive behaviour toward a colleague, or dishonesty. For capability matters, the letter addresses poor performance where previous informal support and review have not led to the required improvement. For absence matters, the letter is used where an employee has been absent without authorisation or has failed to follow the employer's absence notification procedure.

A show cause letter is particularly important before any decision to dismiss. Under Section 94 of the Employment Rights Act 1996, employees with two or more years of continuous employment have the right not to be unfairly dismissed. An Employment Tribunal adjudicating an unfair dismissal claim will examine whether the employer followed a fair procedure, including whether the employee was given a proper opportunity to provide their account. Failure to issue a show cause letter before a decision to dismiss is strong evidence of procedural unfairness. The Advisory, Conciliation and Arbitration Service (ACAS) recommends that disciplinary procedures include written notification of allegations, an investigation meeting, and a disciplinary hearing before any sanction is imposed. HM Revenue and Customs (HMRC) administers PAYE and National Insurance contributions under the Income Tax (Earnings and Pensions) Act 2003, which continue to apply throughout any disciplinary suspension period.

A properly drafted Show Cause Letter (UK) should include the following key elements to comply with the ACAS Code of Practice on Disciplinary and Grievance Procedures and the Employment Rights Act 1996.

Employee identification and date: The letter must clearly identify the employee by name, job title, and department, and must be dated. The date is important because it starts the clock on any response deadline and may be relevant to any subsequent Employment Tribunal proceedings under the Employment Rights Act 1996.

Description of the alleged issue: The letter must describe the specific alleged misconduct, performance failing, or absence in sufficient detail for the employee to understand the nature of the allegation and to prepare a meaningful response. Vague allegations do not give the employee a fair opportunity to respond and may undermine procedural fairness before an Employment Tribunal adjudicating an unfair dismissal claim under Section 94 of the Employment Rights Act 1996.

Relevant facts and dates: The letter should set out the key facts on which the allegation is based, including specific dates, locations, and any witness accounts or documentary evidence that the employer intends to rely on. Where a preliminary investigation has been carried out, the letter should summarise the findings. The ACAS Code of Practice on Disciplinary and Grievance Procedures, issued under Section 199 of the Trade Union and Labour Relations (Consolidation) Act 1992, recommends that investigation findings be shared with the employee before the disciplinary hearing.

Deadline for response: The employee should be given a reasonable time to respond in writing — typically five to ten working days. The letter should state clearly the name of the person to whom the written response should be addressed and the method of delivery. An unreasonably short deadline may be treated as procedural unfairness by an Employment Tribunal.

Right to be accompanied: Under Section 10 of the Employment Relations Act 1999, employees have a statutory right to be accompanied at any formal disciplinary hearing by a trade union representative or a workplace colleague. The letter should inform the employee of this right if a formal hearing is to follow receipt of their response.

Potential consequences: The letter should state the potential consequences if no satisfactory explanation is provided, including the possibility of formal disciplinary action up to and including summary dismissal for gross misconduct. Where dismissal is a potential outcome, the employee must be clearly warned, as an Employment Tribunal will assess whether the employee was aware of the possible sanction.

Protected disclosures and equality considerations: Where the employee may have made a protected disclosure under the Public Interest Disclosure Act 1998, or where the disciplinary matter touches on a protected characteristic under the Equality Act 2010 (age, disability, race, religion, sex, sexual orientation), the employer should seek advice before issuing the letter. The Advisory, Conciliation and Arbitration Service (ACAS) early conciliation service is available under Section 18A of the Employment Tribunals Act 1996. Personal data in disciplinary files is regulated by the Information Commissioner's Office (ICO) under the UK GDPR and Data Protection Act 2018. HM Revenue and Customs (HMRC) administers PAYE under the Income Tax (Earnings and Pensions) Act 2003 throughout any disciplinary suspension.
