Comprehensive guide to how company policies affect dismissal decisions in England and Wales, explaining disciplinary procedures, the Acas Code, procedural fairness, tribunal assessments, contractual implications, and practical steps for employers and employees.

Company policies, procedures and staff handbooks form a critical part of employment relationships in England and Wales. While statutory employment rights such as unfair dismissal originate in law, internal policies influence what constitutes a fair dismissal and how an employment tribunal assesses an employer's conduct. When dismissal decisions are challenged, tribunals look not only at whether there was a valid legal reason for dismissal but also whether the employer followed fair and reasonable procedures - including their own policies and recognised industry standards. This article explains how company policies affect dismissal decisions, the legal framework, tribunal interpretation, practical steps, risks and answers common questions.
What Are Company Policies and Why They Matter
Company policies - including disciplinary, grievance, performance management and dismissal procedures - set out expectations of behaviour, standards of conduct and processes that employers and employees should follow when issues arise. Employers typically publish these in employee handbooks or contracts, and they often reflect best practice as recommended by statutory guidance such as the Acas Code of Practice on Disciplinary and Grievance Procedures.
While internal policies are not law in themselves, they provide the framework within which employers make dismissal decisions. Tribunals consider whether an employer acted within their own policies as part of assessing the reasonableness and fairness of a dismissal. Inconsistent, unclear or poorly applied policies can weaken an employer's position and increase the risk of adverse tribunal outcomes.
The Legal Context: Fair Reason and Fair Procedure
Statutory Framework
Under the Employment Rights Act 1996, employees with sufficient service have the right not to be unfairly dismissed. A dismissal will be fair only if:
- There was a potentially fair reason (such as conduct, capability, redundancy, illegality or “some other substantial reason”); and
- The employer acted reasonably in treating that reason as sufficient justification for dismissal.
Tribunals apply an objective “range of reasonable responses” test: they decide whether a reasonable employer in the same circumstances could have taken the step of dismissal. Company policies are used as benchmarks of procedural fairness and employer expectations when considering whether the employer's response fell within that range.
Procedural Fairness and the Acas Code
The Acas Code of Practice on Disciplinary and Grievance Procedures sets out minimum standards for fair procedures in disciplinary matters that may lead to dismissal. Tribunals must take the Code into account where relevant and can adjust compensation by up to 25% if either party unreasonably fails to follow it. Although the Code is not law, it carries significant weight in tribunal decision-making.
Company policies that reflect the Acas Code - for example in requiring investigations, meetings, representation rights and appeals - demonstrate that the employer's procedures align with recognised fairness principles.
How Tribunals Use Company Policies in Dismissal Decisions
Assessing Procedural Fairness
Tribunals look at whether the employer followed a fair procedure before dismissing an employee. A well-drafted policy guides employers through investigation, warnings, meetings, opportunities for employee response and appeals. Failure to follow these steps can lead a tribunal to find a dismissal procedurally unfair, even if the employer had a valid reason for the dismissal.
Company policies matter because they:
- Define steps and timelines for handling grievances, discipline and performance issues.
- Set out how investigations should be conducted before a dismissal decision is made.
- Provide employees with rights of accompaniment and appeal.
- Establish clear standards for sanctions and dismissal triggers.
If these procedures are not followed, tribunals can consider the dismissal unfair or adjust compensation due to procedural failings.
Contractual Procedures vs Guidance
Not all policies are contractual. Contracts, handbooks and policies may explicitly state whether procedures are contractual obligations or aspirational guidelines. If a policy forms part of the contractual terms, failure to follow it can be a breach of contract and provide additional grounds in a tribunal claim, sometimes leading to both unfair dismissal and contractual claims.
Where policies are non-contractual, tribunals still treat them as indicators of reasonable procedure. Consistency in applying policies - such as giving warnings before dismissal - helps employers show that their decisions were within the reasonable range of responses.
Consistency and Non-Discrimination
Company policies that apply consistently to all employees reduce the risk of discrimination claims. Tribunals may examine whether policies were applied evenly; inconsistent application can suggest bias or unfair treatment, potentially strengthening claims of unfair dismissal or discrimination.
Practical Elements of Policy Application in Dismissal
Investigation and Evidence
A policy that requires a thorough investigation before disciplinary action ensures that dismissal decisions rely on reliable evidence. Failure to investigate properly - or ignoring contradictory evidence - can undermine reasonableness and lead to tribunal findings of unfair dismissal.
Right to be Heard and Representation
Policies often grant employees the right to be accompanied at meetings and to respond to allegations. Tribunals consider whether these rights were respected. Denying representation or failing to allow an employee to present their case can contribute to procedural unfairness.
Appeal Processes
Including an appeal stage in dismissal procedures - and applying it - demonstrates that the employer is willing to review decisions and correct errors. A lack of appeal opportunity or disregard for appeal outcomes can weigh against the employer in tribunal assessments.
Risks of Poor or Ignored Company Policies
Increased Compensation
Tribunals may increase compensation by up to 25% where they conclude an employer has unreasonably failed to follow relevant procedures or the Acas Code.
Findings of Procedural Unfairness
Dismissals may be found unfair where reasonable policies exist but are ignored or applied selectively. Case law and tribunal practice emphasise that employment processes must be transparent, documented and consistently used.
Contractual Breaches
Where policies are incorporated into contracts - for instance, if the contract refers expressly to a handbook procedure - employers risk contractual breach claims in addition to unfair dismissal claims when policies are not followed.
Practical Steps for Employers
Publish and Communicate Policies
Ensure all employees receive and understand key policies on discipline, performance, grievances and dismissal. Policies should be clear, accessible and regularly updated to reflect legal developments and best practice.
Train Managers and HR
Training on how to apply policies, conduct investigations and manage disciplinary processes helps ensure consistency and reduces legal risk.
Follow Procedures Actively
Apply policies in practice - from initial concerns through to any dismissal decision - ensuring meetings, notes, representation rights and appeals are recorded and offered.
Practical Steps for Employees
Understand Your Contract and Policies
Check your contract and employee handbook to know your rights and the procedures your employer is supposed to follow. Policies may contain rights to meetings, representation and appeals.
Raise Grievances Early
Use internal grievance procedures where appropriate; tribunals may reduce compensation if employees unreasonably fail to follow available internal steps.
Keep Records
Document meetings, correspondence and procedural steps taken by the employer. Evidence of procedural failings can strengthen a tribunal claim.
Common Questions
Does following company policy guarantee a fair dismissal?
No. Having and following a clear policy is important, but fairness also depends on whether the reason for dismissal is valid and whether the employer's overall conduct was reasonable.
What if the employer ignores its own policy?
Ignoring internal procedures may contribute to a tribunal finding procedural unfairness and potentially increase compensation awards. Where policies are contractual, it can also lead to breach of contract claims.
Can a tribunal enforce an appeal process?
Tribunals cannot enforce internal appeal rights directly, but failure to honour appeal procedures can be considered unfair conduct when assessing the dismissal.
Final Thoughts
Company policies play a significant role in dismissal decisions in England and Wales. They complement statutory requirements by setting out fair processes and expectations for how issues leading to dismissal should be handled. Tribunals consider company policies - especially disciplinary and grievance procedures - when assessing procedural fairness under unfair dismissal law. Employers reduce legal risk by publishing clear policies, training managers, and consistently following written procedures. Employees should understand their contractual and procedural rights, use internal procedures where available, and document any procedural failings. By aligning internal practices with recognised standards like the Acas Code, both employers and employees can manage dismissals in a way that withstands legal scrutiny.
