Implied Mutual Trust and Confidence in Singapore Employment Contracts (2026): What the SAP Asia Ruling Means for Dismissals and Employer Duties

Mutual trust and confidence Singapore has moved from the realm of academic debate into live compliance territory, and the 2026 SAP Asia decision is a significant reason why. The case addresses whether an implied term of mutual trust and confidence operates within the employment relationship, obliging both employer and employee to refrain from conduct, without reasonable and proper cause, calculated or likely to destroy or seriously damage the relationship. For HR directors, in-house counsel and founders, this is not a theoretical shift; it reshapes how dismissals, suspensions and internal investigations should be conducted and documented.

This guide explains the issues the decision raises, how they interact with statutory protections under the Employment Act, and the concrete steps employers in Singapore should take now to reduce legal risk. Employers should confirm the precise scope and ratio of the decision with their advisers by reference to the published judgment, as appellate consideration can refine how such implied terms apply in Singapore.

What SAP Asia (2026) Addressed, A Plain-English Summary

The SAP Asia decision is significant because it engages with the position taken in other common law jurisdictions, such as England and Wales, where the implied term of mutual trust and confidence has long been recognised as governing the conduct of both parties to an employment contract. The question of how far this implied term operates in Singapore has been the subject of careful judicial attention, and the decision considers a contractual obligation that sits alongside the written terms of the employment contract.

Case Context

The dispute arose in the familiar context of a terminated employee who challenged the manner in which the employment relationship ended. The employee contended that the employer’s handling of the matter, the process leading to termination and the conduct surrounding it, fell short of the standards implicit in a modern employment relationship. The factual matrix placed the employer’s investigatory and decision-making conduct under judicial scrutiny, giving the court the opportunity to consider the role of an implied duty of good faith and fair dealing in the parties’ interactions.

The Court’s Treatment of the Implied Term

The central issue is whether, and to what extent, an implied term of mutual trust and confidence forms part of the employment contract in Singapore. In substance, the principle is that neither party may, without reasonable and proper cause, engage in conduct likely to destroy or seriously damage the relationship of trust between them. The reasoning emphasises that such an implied term is concerned not with the substantive decision alone, for example, the decision to dismiss, but with the manner in which the employer exercises its powers. Arbitrary, capricious, or procedurally unfair conduct in the exercise of contractual discretion may itself be problematic, even where the ultimate decision might have been defensible on its merits.

This distinction between the decision and the manner of its execution is the practical heart of the issue. Employers retain the right to manage, discipline and dismiss; what the implied term is concerned with is how that right is exercised. The authoritative text of the judgment should be consulted directly through the Singapore courts’ judgment resources, and employers relying on the decision for policy change should ensure their advisers work from the published reasoning rather than secondary summaries.

Why This Matters to Employers

Historically, many Singapore employers operated on the working assumption that so long as contractual notice was given and statutory requirements observed, the manner of dismissal carried limited independent legal risk. Greater judicial attention to mutual trust and confidence in the Singapore context changes that calculus. Procedural shortcuts, a rushed investigation, a suspension imposed without explanation, a summary dismissal based on untested allegations, may give rise to arguments of breach of contract in their own right. The consequence is that process, documentation and good-faith conduct are not merely good practice; they can be legally material to the employer’s exposure.

Legal Basis, Implied Term Versus Statutory Duties Under the Employment Act

Understanding the position requires separating two distinct sources of obligation: the common law implied term, and the statutory framework administered by the Ministry of Manpower (MOM) and set out in the Employment Act 1968. The two operate together, and compliance with one does not guarantee compliance with the other.

What Is an Implied Term?

Singapore courts, like other common law courts, imply terms into contracts in defined circumstances. A term may be implied in fact where it is necessary to give business efficacy to the contract or where it is so obvious that it “goes without saying”, the classic tests reflected in Singapore’s own framework for implication set out by the Court of Appeal. Alternatively, a term may be implied in law as a default incident of a particular category of contract, such as the employment relationship.

The implied term of mutual trust and confidence, where recognised, is best understood as a term implied in law: it attaches to employment contracts as a matter of policy because of the nature of the relationship, rather than because the parties specifically turned their minds to it.

The practical implication is that, where the term applies, it does so by default. An employer should not assume it is absent simply because the written contract is silent on good faith or fair process. Drafting a contract to exclude or narrow the implied term is a delicate exercise that should only be attempted with specialist legal advice, and even then its enforceability may be contested.

Interaction with the Employment Act

The Employment Act 1968, accessible in full via Singapore Statutes Online, sets out the statutory architecture for termination, including notice periods, payment in lieu of notice, and the framework governing dismissal. MOM’s guidance on termination of employment explains the administrative expectations, including the right of eligible employees to lodge wrongful dismissal claims and the dispute resolution routes available, principally through the Tripartite Alliance for Dispute Management (TADM) and the Employment Claims Tribunals.

The implied term of mutual trust and confidence does not displace these statutory provisions; it operates alongside them. An employer may satisfy every statutory formality, giving correct notice, making the correct payment, and still face a breach-of-contract argument if the manner of dismissal or the conduct leading to it is said to have breached the implied term. The statutory wrongful dismissal regime and a common law claim are different causes of action with different remedies and forums. Employers should treat Employment Act compliance as the floor, not the ceiling, of their obligations.

Remedies Available

Breach of the implied term is a breach of contract, and the primary remedy is damages. These are assessed on ordinary contractual principles and the recoverability of loss is subject to the limits established by the courts, which have historically constrained recovery for the manner of dismissal. In limited circumstances, an employee may seek injunctive relief, for example to restrain a flawed disciplinary process before it concludes. Reinstatement is not a routine remedy in private employment but may be ordered in the statutory wrongful dismissal context through the Employment Claims Tribunals. The availability and quantum of remedies will turn on the facts, and early legal assessment is essential where a claim is anticipated.

Practical Implications for Dismissals and Investigations

This is where the issue bites hardest in practice. Greater attention to mutual trust and confidence means that the integrity of internal processes is directly relevant to legal exposure. The sections below set out practical workflows for investigations, suspension, dismissal and confidentiality.

Investigations, Process, Suspension and Fair Procedure

A defensible investigation is a frontline risk-management tool. Employers should adopt a structured, documented process that demonstrates good faith and reasonable cause at every stage. A workable sequence is as follows:

1. Preliminary assessment. On receipt of a complaint or indication of misconduct, assess whether formal investigation is warranted and record that assessment. Avoid pre-judging the outcome.
2. Appoint an impartial investigator. The investigator should have no personal involvement in the allegations and no conflict of interest. For sensitive matters, consider an external investigator.
3. Scope and plan. Define the allegations clearly, identify relevant documents and witnesses, and set a realistic timeline. Unreasonable delay can itself damage the relationship of trust.
4. Collect and preserve evidence. Secure relevant records early, including emails, system logs and documents, and store them in a manner that preserves integrity and chain of custody.
5. Put allegations to the employee. Give the employee a fair opportunity to respond to the specific allegations, ideally in writing and in a meeting, and allow a reasonable period to prepare.
6. Reach a reasoned conclusion. Document the findings, the evidence relied on, and the reasoning. A conclusion that is not supported by the evidence is vulnerable.
7. Communicate the outcome. Inform the employee of the decision and the basis for it, and record the communication.

Timelines should be proportionate to the complexity of the matter. For straightforward cases, an investigation measured in days to a few weeks is often reasonable; complex matters may take longer, but prolonged uncertainty without communication risks damaging the relationship of trust.

Suspension and Interim Measures

Suspension pending investigation is not automatically a breach of mutual trust and confidence, but it should be justified and proportionate. Suspension should not be a default or punitive step. Before suspending, employers should ask whether it is genuinely necessary, for example, to preserve evidence, protect other employees, or prevent interference with the investigation, and whether a less intrusive alternative exists, such as reassignment or restricted access.

Where suspension is imposed, it should normally be on full pay unless the contract clearly provides otherwise, it should be for the shortest period reasonably necessary, and the reasons should be communicated to the employee in neutral, non-prejudicial terms. A suspension letter should make clear that suspension is a neutral act and not a disciplinary sanction or a finding of guilt. Keeping the employee informed of progress during the suspension helps demonstrate good faith.

Summary Dismissal Versus Progressive Discipline

Summary dismissal, termination without notice for serious misconduct, carries elevated risk because it bypasses the usual notice protections and signals a serious adverse finding. Under the Employment Act, an employer may dismiss without notice only after due inquiry on the ground of misconduct inconsistent with the conditions of service. Employers should reserve summary dismissal for genuinely serious misconduct supported by cogent evidence gathered through a fair process. Dismissing summarily on the basis of untested allegations, or before the employee has had an opportunity to respond, is precisely the kind of conduct that invites challenge.

For lesser matters, progressive discipline, warnings, performance improvement plans, and graduated sanctions, is both fairer and more defensible. A documented progression demonstrates that the employer acted with reasonable and proper cause and gave the employee a genuine chance to address concerns. The threshold for summary dismissal is high; the standard of a fair, documented disciplinary process should be met in every case.

Confidentiality and Data Protection During Investigations

Investigations inevitably involve personal data, and employers must handle that data consistently with their obligations under the Personal Data Protection Act 2012. Access to investigation materials should be limited to those with a genuine need to know. Witness accounts and the identity of complainants should be protected where appropriate, balancing the subject employee’s right to respond against the legitimate interests of others. Investigation records should be stored securely and retained only for as long as necessary. Mishandling confidential information during an investigation can itself erode trust and compound an employer’s exposure.

Model Contract Clauses and Policy Changes Employers Should Adopt

The following clause and policy suggestions are provided for illustrative purposes only and must be reviewed and adapted by qualified counsel before use. They are a starting point for discussion, not off-the-shelf drafting.

Suggested Implied-Term-Compatible Clauses

• Good-faith conduct acknowledgement. A clause recognising that both parties will act in good faith and will not, without reasonable and proper cause, conduct themselves in a manner likely to seriously damage the relationship of trust and confidence. This signals alignment with the implied term rather than attempting to exclude it.
• Investigatory cooperation clause. A clause requiring the employee to cooperate reasonably with legitimate internal investigations, while affirming the employer’s commitment to conduct investigations fairly and impartially.
• Disciplinary procedure clause. A clause incorporating the employer’s disciplinary and grievance policies by reference, with language clarifying whether those policies are contractual or non-contractual, a distinction with real consequences for enforceability.
• Suspension clause. An express right to suspend on full pay for a defined, proportionate period where necessary to conduct an investigation, drafted to reinforce that suspension is a neutral measure.

Policy Templates to Update

• Investigation policy. Set out the standard steps, timelines, roles and documentation requirements described above, so that process consistency can be demonstrated.
• Disciplinary policy. Define misconduct categories, sanctions, the right to respond, and the progression from informal to formal action.
• Suspension letter template. A neutral template confirming the fact of suspension, the reason in general terms, the pay position, the expected duration, and a contact point for the employee.
• Outcome and decision letter templates. Standardised letters that record findings, reasoning and the employee’s response, reducing the risk of inconsistent or unreasoned communications.

Because the enforceability of contractual language touching on the implied term is sensitive, every clause above should be subject to a legal review step before adoption. Where AI tools are used to accelerate drafting, a qualified lawyer must review and confirm the output against current statute and case law.

Checklists for HR and In-House Counsel, A Day-One to 90-Day Plan

The following time-bound checklist translates the issue into an actionable compliance programme.

Immediate, within 7 days:

• Brief senior HR and management on the implied term and its practical reach.
• Pause any in-flight dismissals or suspensions pending a quick fairness review.
• Identify the contracts, policies and letter templates that will require review.

Short-term, within 30 days:

• Finalise a documented investigation protocol with defined steps, roles and timelines.
• Update suspension, disciplinary and investigation policies and standard letters.
• Deliver initial training to HR and line managers on fair process and good-faith conduct.

Medium-term, within 90 days:

• Complete a legal review of employment contract templates and incorporate agreed clauses.
• Roll out comprehensive manager training on investigations, suspension and discipline.
• Audit a sample of recent dismissals to identify process gaps and remediate systemic issues.
• Set a recurring review cycle so policies stay aligned with developing case law.

Remedies, Dispute Routes and Likely Outcomes

Where an employee believes the implied term has been breached, several routes may be available, and employers should understand each to assess exposure realistically.

Wrongful Dismissal, Breach of the Implied Term and Damages

An employee may bring a civil claim for breach of contract, including breach of the implied term of mutual trust and confidence where it is found to apply. The principal remedy is damages assessed on contractual principles, reflecting losses flowing from the breach and subject to established limits on recoverability. Separately, eligible employees may pursue a statutory wrongful dismissal claim through TADM mediation and, if unresolved, the Employment Claims Tribunals. These are distinct causes of action, and an employer may face one, the other, or both depending on the circumstances. Reinstatement is not a standard private-law remedy but can be ordered in the statutory context.

Alternative Dispute Resolution and TADM Mediation

Many employment disputes in Singapore are resolved through mediation at the Tripartite Alliance for Dispute Management (TADM) before reaching the Employment Claims Tribunals or the civil courts. Mediation offers a faster, lower-cost route that preserves relationships and avoids the reputational exposure of litigation. Employers should treat early, good-faith engagement in dispute resolution as consistent with, and supportive of, their obligations under the implied term. Where a dispute proceeds to civil litigation, the quality of the employer’s investigation and documentation will be decisive.

Conclusion and Next Steps

Greater judicial attention to mutual trust and confidence in Singapore marks an important moment in local employment law. The development does not strip employers of their right to manage, discipline and dismiss, but it does underscore that those powers should be exercised fairly, proportionately and in good faith, and that the process be documented well enough to withstand scrutiny. The immediate priorities are clear: review in-flight dismissals and suspensions, formalise a defensible investigation protocol, update contracts and policies with specialist input, and train managers on fair process. Employers that act now can convert a developing legal risk into a durable compliance advantage.
