Collective Redundancies

Collective Consultation in Redundancy: What’s Changed?


What is Collective Consultation?


Collective consultation is a statutory process employers must follow when proposing to make 20 or more redundancies at one establishment within a 90‑day period. The aim is to consult with employee representatives about ways to:


  • Avoid redundancies
  • Reduce the number of redundancies
  • Mitigate the consequences of redundancies


Failure to comply can result in significant financial penalties.



What Are the New Rules?


Recent legal developments have clarified how collective consultation thresholds should be assessed.


Key Change


The requirement to collectively consult is now triggered by the total number of redundancies across the organisation, not just at a single site, where dismissals are connected.


This means:


  • Employers must look beyond individual workplaces
  • Redundancies forming part of the same proposal may need to be aggregated
  • Collective consultation may be required more often than previously thought



When Does Collective Consultation Apply?


Collective consultation is required when:


  • 20 or more redundancies are proposed
  • Within a 90‑day period
  • Where dismissals are part of the same proposal, even if spread across locations



Who Must Be Consulted?


Employers must consult with:


  • A recognised trade union, or
  • Elected employee representatives


Consultation must be meaningful and take place before final decisions are made.



Minimum Consultation Periods


The minimum consultation periods remain unchanged:


  • 20–99 redundancies: at least 30 days before the first dismissal
  • 100+ redundancies: at least 45 days before the first dismissal


Employers must also notify the Secretary of State using form HR1.



Risks of Getting It Wrong


If collective consultation obligations are breached:


  • Employment Tribunals can award a protective award of up to 90 days’ gross pay per affected employee
  • Reputational damage and employee relations issues may arise



Practical Steps for Employers


  • Review redundancy proposals across the whole business
  • Identify whether redundancies are connected
  • Start consultation early
  • Keep clear records of decision‑making and consultation
  • Take legal advice where thresholds may be met

Employment experts foresee an increase in employment tribunal cases brought by employees as a result of employers requiring employees back into the office, full time. Those who try to avoid days in the office may be faced with their employers using entry-gate data to track staff attendance. The Telegraph reports that a number of companies are now advocating a full five-day return to the office, with others enforcing a minimum number of days in the workplace. Administrative staff at Boots, who previously worked in the office three days a week, will be required to return to the office five days per week from September. Earlier this year, an Employment Tribunal rejected the case of a senior manager who claimed against her employer, the Financial Conduct Authority, because she wanted to work at home full-time. Judge R Richter ruled that the FCA was within its rights to reject the employee's request stating that there are “weaknesses with remote working.....which will no doubt be the subject of continued litigation.” Is working from home so bad? According to KPMG’s 2023, CEO Outlook Survey ( Current trends in remote working (kpmg.com) , attracting and retaining talent is a top operational priority for CEOs to achieving their 3-year growth objectives and believe that remote working can play an important role in supporting talent retention and accessing new talent markets. There will no doubt be an increased number of claims brought against employers as remote working dissipates and employer's start to change the working dynamics.

Menopause symptoms can have a significant impact on women at work. Research by the Chartered Institute of Personnel and Development found that two thirds of working women between the ages of 40 and 60 with experience of menopausal symptoms said they have had a mostly negative impact on them at work. Of those who were negatively affected at work: 79% said they were less able to concentrate. 68% said they experienced more stress. nearly half (49%) said they felt less patient with clients and colleagues, and 46% felt less physically able to carry out work tasks. Baroness Kishwer Falkner, chair of the EHRC, said: “As Britain’s equality watchdog, we are concerned both by how many women report being forced out of a role due to their menopause-related symptoms and how many don’t feel safe enough to request the workplace adjustments."

The EAT has held that an employee’s redundancy dismissal was unfair where the employer failed to carry out meaningful workforce consultation at a formative stage. The respondent company carried out a scoring exercise using a standard set of subjective criteria. The claimant scored lowest in out of three in his pool. The respondent then met with the claimant three times before dismissing for redundancy. No consultation took place with the workforce prior to the scoring exercise. The EAT held that there was a clear absence of consultation at the formative stage, which meant there was no opportunity to discuss different approaches to any aspect of the employer’s redundancy process. The decision underlines the importance of appropriate workforce consultation, even where collective consultation obligations are not triggered. De Bank Haycocks v ADP RPO UK Ltd [2023] EAT 129

Strike Action - what's going on? Trade unions are representing NHS staff are in a dispute with the government over the 2022/23 pay award.

As a consequence, and for the first time in history, nurses and ambulance staff have gone on strike, represented by Trade Unions, regarding a dispute over wages. Royal College of Nurses (RCN) is calling for a 19% pay rise. The government says this is unaffordable.
