Employee Gross Misconduct – Advice for Employers
When employers contact me about employee gross misconduct, it is usually because something serious has happened and they are unsure what to do next. This usually involves behaviour that appears so serious you may have no option but to consider dismissal.
Gross misconduct describes behaviour so serious that it destroys the working relationship. Although some cases look obvious straight away, many others are more complex. In this article I explain how employee gross misconduct appears in real UK workplaces and how employers can deal with it fairly. I use examples drawn from genuine situations, as these often help employers understand how to approach the process without risking a claim.
How employee it appears in everyday scenarios
The most common form of employee gross misconduct involves acts that undermine trust. Theft is the example many employers think of first. I once advised a retail business whose employee removed returned stock and placed it into their own bag. The act was caught on CCTV. Even so, we still carried out a full investigation and held a disciplinary meeting. Tribunals expect a fair process even when the evidence appears clear.
Another example would be physical aggression. A landscaping firm contacted me after an argument between two staff members escalated. One employee pushed another during a dispute over broken equipment. There were no injuries but the intent mattered. Acts of aggression often fall within employee gross misconduct because they place others at risk and damage trust. Even then, we looked at whether any provocation played a part.
Serious breaches of health and safety rules are also common. A warehouse employee who ignores lock-off procedures may expose others to danger. Tribunals tend to treat these incidents as gross misconduct because the potential harm is significant. Even a single breach may justify dismissal if the rule is clear and the employee understood it.
Employee gross misconduct involving dishonesty
Dishonesty continues to be a major factor in gross misconduct cases. I once supported a company after an employee falsified mileage claims. The extra amounts were small but the behaviour was deliberate. Tribunals often say that honesty is central to the employment relationship. Once trust is damaged it can be difficult to repair.
Another issue involves employees misrepresenting their qualifications. A manufacturer hired a supervisor who claimed to hold a safety certificate required for the role. When it later emerged that the certificate did not exist, the employer dismissed after investigation. Even though the employee’s work had been acceptable, the deception at the start of employment made the relationship untenable.
Attempts to hide mistakes can also amount to employee gross misconduct. For example, a logistics worker who damages goods and then conceals the issue may cause more disruption than the damage itself. When the concealment is deliberate, employers may treat it as gross misconduct even if the underlying mistake was minor.
Employee gross misconduct outside the workplace
Some incidents occur away from work but still affect employment. A conviction for a violent offence may raise concern, especially in roles that involve dealing with the public. Employers must consider the relevance to the job. One of my clients had an employee arrested after a late-night incident. Once we reviewed the facts it became clear the employee had acted in self-defence. The employer issued a warning rather than dismissing. This was the right approach because the incident had limited impact on their work duties.
Social media is another area where employee gross misconduct may arise. Offensive comments posted publicly can damage an employer’s reputation. A single post may justify dismissal if the connection to the employer is clear. Even then, you must investigate and allow the employee a chance to respond.
Misconduct involving alcohol may also fall into this category. An employee who behaves inappropriately at a work event can cause significant reputational harm. What initially seems minor may turn out to be more serious once witnesses are interviewed.
Why process still matters
Even when the behaviour appears serious, you must still follow a fair and reasonable procedure. Tribunals often focus on the process rather than the misconduct itself. A quick investigation, witness statements and a meeting with the employee all help protect your position.
Your disciplinary policy should guide you. Many employers contact me early because they worry about making the wrong decision.
If an employee raises concerns about fairness, health or training, you should consider these before making any decision. Tribunals expect employers to look at the full context.
When misconduct looks borderline rather than clear-cut
Not all misconduct sits cleanly within the category of employee gross misconduct. Some cases are borderline. For example, insubordination may be serious in one setting and minor in another. A construction worker refusing to use a machine because they believe it is unsafe may be acting reasonably. Another employee refusing a basic instruction without explanation may not.
Training failures also create problems. If an employee breaches a safety rule because they were never trained, disciplinary action may be unfair. I advised a logistics employer who dismissed an employee for breaching a forklift procedure. It turned out they had not received proper training. The employer reversed the decision once the issue came to light.
Situations involving redundancy can also create confusion. Behaviour that occurs during the consultation process may feel like misconduct. Still, employers should distinguish between objections raised in good faith and behaviour that truly undermines trust.
