Members of the Employment Lawyers Association and Members of the Association of Partnership PractitionersThere are five potentially fair reasons for dismissal. They are conduct, capability, redundancy, breach of a statutory duty or restriction, and  "some other substantial reason of a kind as to justify the dismissal” or to put it more simply, “SOSR”.

SOSR has long been referred to as a catch-all provision for potentially fair dismissals. If an employee does not fit squarely within any of the other four reasons, employers have tended to rely on SOSR.

The difficulty with SOSR is that it is not defined in statute and there is no statutory guidance on what it means. It has therefore been left to case law to develop what SOSR dismissals may constitute.

Examples from case law include:

• a breakdown in trust and confidence between the employer and employee,
• personality clashes - where the conflict has caused significant disruption to the business,
• business reorganisations - not amounting to redundancy, as this squarely falls within one of the other fair reasons,
• third party pressure to dismiss - for example from a client,
• expiry of a fixed term contract – for instance, the expiry of a fixed term maternity cover contract
• a refusal to accept changes to terms and conditions - where there are business reasons for the change and the change is not trivial.

As can be seen, there are a range of varied circumstances which may lead to an employee’s dismissal being treated as SOSR. However, employers should be cautious when seeking to rely on the “catch all” provision. Employers must still ensure that they act reasonably in all the circumstances of the case. The question of reasonableness includes considering whether the employer followed a fair procedure. For instance, as a minimum, consultation with the employee would be expected before a decision to dismiss for SOSR is made. Employers should also consider any alternatives to dismissal and only dismiss as a last resort. Further, the employee should be given the right to appeal the dismissal.

Whilst a breakdown in trust and confidence may be a common reason relied on by employers for SOSR dismissals, it should not be used to avoid following the proper procedures for other types of dismissal such as poor performance or misconduct. Indeed, the employer’s decision to dismiss for SOSR may ultimately be subject to scrutiny by a Tribunal.  The Tribunal will look at the surrounding circumstances and may decide that the decision to dismiss was unreasonable and not a SOSR, treating it as unfair.

Our Employment Team


I just wanted to say thank you for all your advice, support and expertise during the process.

Your calm, measured and objective approach really helped keep me calm and confident that I was making the right decisions.

No one wants their employment to end like this, but its nice to walk away on my own terms, with some security.

Employment Client of Jessica Bass

I was very happy with the quickness and professionalism of your services. I can only recommend you to anyone who needs employment legal advice.

“Thanks [Sukhi Bagha] for enabling the sale to go through so quickly and so efficiently. Having bought and sold several properties in the UK, I can honestly say that you have proved to be the most effective conveyancing professional we've dealt with”.

Property Law clients

"From the start, the service I received from both Corinne and Jennifer was excellent. I always felt I was in very capable and professional hands. They negotiated an extension of the free rental period for my commercial lease by a month without being asked, which was very proactive and helped a lot. I will definitely be using Curzon Green again."

Local business owner

Thank you so very much for your help, advice and support through what has been a very unpleasant time. Knowing that you were ‘looking after us’, was an immense help.

My only regret is not contacting you sooner.

You have been nothing short of amazing over the past 15 months. I would have never had the courage to pursue this were it not for your unending support, hard work, and conviction... You were the one who made it all happen.

Senior Legal Counsel
US Company

I came to Rob Green having suffered a serious permanent spinal injury. This injury arose from circumstances where I had to make a claim for damages against a driver who had caused a car accident, the medical specialists who treated me and also a personal accident insurer (which was refusing to pay out on a life assurance policy).

Martin Scrivener
Former Car Mechanic

As a first time buyer I did not have a clue about the conveyancing process. My sister recommended me to Curzon Green Solicitors. Curzon Green acted as my solicitors for the purchase. They understood that I knew nothing about buying houses and so they talked and walked me step-by-step through the process.

Miss Bradley
Head of Girls' P.E. at Chesham Grammar School

From the start of my search for legal advice Curzon Green stood out from the competition. Their approach was fresh, open, jargon-free and without initial charges for the initial exploratory conversation. I was looking for a different, collaborative means to sort my divorce, and Curzon Green were well-qualified and experienced. Having engaged his services, he first explained the outline of the law in this area, and provided a clear structure of how to go forward to engage with my wife and her solicitor.

Mr F, High Wycombe

Curzon Green is a relatively new company but ECS has the confidence to say that they will have a long and prosperous future, if they continue to provide to their clients the same level of service that ECS has received.
