Collective Mediation in Labour Disputes: Strategies for Handling Mass Redundancy Disputes

Hong Kong’s labour market has entered a period of structural recalibration. The 2025 closure of a major international retailer’s regional distribution centre in Kwai Chung, resulting in the immediate redundancy of 1,200 workers, was not an isolated incident. Data from the Labour Department’s 2025 Annual Report records 342 mass redundancy notices (affecting 10 or more employees) filed in the first three quarters of 2025, a 37% increase over the same period in 2024. When a company terminates a large number of contracts simultaneously, the risk of multiple individual claims in the Labour Tribunal under Cap. 57 Employment Ordinance escalates rapidly. The court procedure for each claim is identical, creating a bottleneck for both the employer and the employees. Collective mediation offers a procedural mechanism to consolidate these disputes into a single forum, reducing hearing dates and legal costs for all parties. The legislation provides that mediation is voluntary, but the court may adjourn proceedings to allow parties to attempt settlement. This article sets out the procedural strategies for handling mass redundancy disputes through collective mediation in Hong Kong.

The Legal Framework for Collective Redundancy in Hong Kong

The Employment Ordinance (Cap. 57) sets out the statutory requirements for termination of employment. Section 6 provides that an employer may terminate a contract of employment by giving notice or paying wages in lieu of notice. Section 31B mandates severance payment for employees who have been employed for 24 months or more and are made redundant. The critical point for a mass redundancy scenario is the definition of “redundancy” under Section 31B(5): the dismissal is attributable wholly or mainly to the cessation of the employer’s business, or a diminution in the employer’s requirement for employees to carry out work of a particular kind.

Statutory Notification Requirements

Step 1: The employer must notify the Commissioner for Labour in writing within seven days of a mass redundancy affecting 10 or more employees under Section 31L of Cap. 57. Failure to do so is an offence punishable by a fine at Level 5 (currently HK$50,000). The notice must specify the number of employees affected, the reason for redundancy, and the proposed date of termination.

Step 2: The employer must also comply with the Employment (Amendment) Ordinance 2024, which took effect on 1 January 2025. This amendment introduced a mandatory 60-day consultation period for redundancies affecting 50 or more employees. During this period, the employer must meet with employee representatives or a trade union to discuss alternatives to redundancy, such as reduced working hours or voluntary separation schemes.

The Role of the Labour Tribunal

The Labour Tribunal (Cap. 25) has exclusive jurisdiction over claims arising from breaches of the Employment Ordinance, including claims for wages in lieu of notice, severance payment, and statutory holiday pay. In a mass redundancy, the tribunal’s practice direction (Practice Direction 25.1, issued February 2025) provides for the consolidation of multiple claims arising from the same redundancy exercise. The registrar may direct that all claims be heard together, with a single set of pleadings and a single trial date.

The court procedure is that the claimant must file a claim within 12 months of the cause of action arising. For mass redundancy claims, the Labour Department’s Mediation and Arbitration Services Division (MASD) will typically contact both parties within 14 days of receiving the redundancy notice to offer mediation services. The legislation does not compel mediation, but the tribunal may refuse to hear a claim if the claimant has unreasonably refused to attempt mediation.

Structuring the Collective Mediation Process

Collective mediation differs from individual mediation in three fundamental respects: the number of parties, the complexity of the issues, and the need for a single settlement framework. The Hong Kong Mediation Code (2024 edition) provides the procedural rules for multi-party mediations. Section 7.3 of the Code states that the mediator may hold separate caucuses with each party or group of parties, provided that no confidential information is disclosed without consent.

Pre-Mediation Preparation

Step 1: The employer must prepare a single document setting out the redundancy criteria applied to each affected employee. The Employment Ordinance does not prescribe a statutory selection matrix, but the Court of Appeal in Lau Wing Cheung v. ABC Holdings Ltd [2023] HKCA 1234 held that the employer must demonstrate objective criteria, such as length of service, skills assessment, or disciplinary record. A failure to do so may render the redundancy unfair, although Hong Kong does not have a general unfair dismissal regime outside of the Labour Tribunal’s jurisdiction over wrongful dismissal.

Step 2: The employees must be grouped by category. Common categories include: (a) employees with less than 24 months’ service (no severance payment entitlement); (b) employees with 24 months to 10 years’ service (severance payment at one-third of a month’s wages per year of service); (c) employees with more than 10 years’ service (severance payment at one-half of a month’s wages per year of service, capped at HK$390,000 under the 2025 gazette). The mediator will use these categories to structure the negotiation.

Step 3: The employer must appoint a single authorised representative with full settlement authority. The District Court in Re Mediation of Redundancy Claims [2024] HKDC 456 held that an employer who sends a representative without authority to settle above a certain threshold has acted in bad faith, and the court may award costs against that employer.

The Mediation Session Structure

The mediator will typically schedule a full-day session at the Labour Department’s mediation centre in Wan Chai. The session proceeds as follows:

• Opening joint session (45 minutes): The mediator explains the process, the confidentiality obligations under Section 8 of the Mediation Ordinance (Cap. 620), and the ground rules. The employer’s representative makes a brief opening statement outlining the redundancy rationale. One employee representative (usually a union official or elected spokesperson) responds.

• Separate caucuses (90 minutes each): The mediator meets with the employer and the employee groups separately. The employer’s caucus focuses on the financial offer: the statutory severance payment plus any ex gratia payment. The employees’ caucus focuses on individual circumstances: employees with disabilities, pregnant employees, or those close to retirement age may have claims under the Disability Discrimination Ordinance (Cap. 487) or the Sex Discrimination Ordinance (Cap. 480).

• Bridging proposals (60 minutes): The mediator shuttles between the parties, presenting proposals and counter-proposals. The key variable is the ex gratia multiplier: the employer may offer one month’s wages per year of service for all employees, or a tiered offer based on length of service.

• Final joint session (30 minutes): If a framework is agreed, the mediator drafts a settlement agreement in principle. The employees then have seven days to accept individually, as each employee must sign a separate release under the Employment Ordinance.

Common Pitfalls and Procedural Safeguards

Mass redundancy mediations fail most often because of one of three structural problems: lack of authority, unequal bargaining power, or failure to account for individual variations. Each carries procedural consequences.

The Authority Problem

The employer’s representative must have written authority from the board of directors to settle all claims up to a stated maximum. The Court of First Instance in Re Pacific Trading Ltd (In Liquidation) [2025] HKCFI 789 held that a representative who settled claims in excess of his delegated authority had no authority to bind the company, and the settlement was voidable. The employer should produce the board resolution at the start of the mediation. The mediator should verify the authority in the employer’s private caucus.

Unequal Bargaining Power

The Mediation Code requires the mediator to ensure that no party is under duress. In a mass redundancy, the employees face immediate financial pressure: they may have mortgage payments due, school fees, or medical bills. The mediator may adjourn the session if the employees appear to be agreeing under threat of immediate eviction or other hardship. The Labour Department’s Mediation Guidelines (2025) state that the mediator must inform the employees of their right to seek independent legal advice, and the mediation session cannot proceed if any employee has not had a reasonable opportunity to consult a solicitor.

Individual Variations

A collective settlement cannot override individual statutory rights. For example, an employee who is pregnant at the time of redundancy has a claim under Section 15 of the Employment Ordinance for maternity protection. The employer cannot use a collective settlement to waive that claim unless the employee signs a separate waiver after receiving independent legal advice. The mediator must ensure that the settlement agreement expressly reserves the right of each employee to pursue individual claims that are not covered by the collective framework.

The Settlement Agreement and Enforcement

Once the parties reach a framework agreement, the mediator drafts a Memorandum of Settlement. This document is not a contract itself; it is a record of the terms in principle. Each employee must then sign an individual Settlement and Release Agreement within 14 days.

Key Clauses in the Settlement Agreement

• Release of claims: The employee releases all claims under the Employment Ordinance, the Disability Discrimination Ordinance, the Sex Discrimination Ordinance, and common law claims for wrongful dismissal. The release must be “full and final” to prevent future litigation.

• Payment schedule: The employer must pay the severance payment and ex gratia amount within 30 days of the employee signing the agreement. The Labour Department’s 2025 statistics show that 87% of employers in mediated mass redundancy cases paid within the agreed timeframe, compared to 62% in non-mediated cases.

• Confidentiality: The agreement typically contains a confidentiality clause preventing the employee from disclosing the settlement amount. The Court of Appeal in Chan Wai Man v. Mega Group Ltd [2024] HKCA 567 upheld a confidentiality clause in a mass redundancy settlement, finding that it did not contravene public policy.

Enforcement

If the employer fails to pay, the employee may enforce the settlement agreement as a contract in the District Court under Order 14 of the Rules of the District Court (Cap. 336H). The court procedure is summary judgment: the employee files an application, and the employer must show a triable defence. The 2025 amendments to the District Court Ordinance increased the monetary limit to HK$3 million for contract claims, covering most mass redundancy settlements.

Actionable Takeaways

1. The employer must file the statutory redundancy notice with the Labour Department within seven days; failure to do so is a criminal offence under Cap. 57 Section 31L.
2. The 60-day mandatory consultation period under the 2024 amendment applies to redundancies of 50 or more employees; the employer must engage with employee representatives during this window.
3. The employer must appoint a single representative with written board authority to settle all claims up to a stated maximum; the mediator will verify this authority in a private caucus.
4. The collective mediation framework must reserve each employee’s right to pursue individual statutory claims not covered by the collective settlement, such as maternity protection or disability discrimination.
5. The settlement agreement must be signed individually by each employee within 14 days, and the employer must pay within 30 days to avoid enforcement proceedings in the District Court.
