Effective conflict and dispute management is essential for the correct functioning of any workplace. In most businesses, addressing workplace disputes is the responsibility of the Human Resources department or of a designated in-house team. The most common types of formal workplace disputes include:

Grievances

Before raising a formal grievance, employees who have concerns or complaints should raise the issue with their line manager informally. This can be done verbally.

If the above fails, employees are entitled to start a formal grievance procedure. The details on how such procedure is to be conducted vary from company to company, and are outlined in the company's or employee's handbook. It is also possible to find information on the grievance procedure from HR staff, and in some cases the details will be part of the employment contract.

Irrespective of the company's specific procedure, all grievances must be put into writing. A meeting between the employee and the employer will follow in an attempt to resolve the issue. After the meeting, employers must write to the employee informing them of their decision, action to be taken, and how to appeal the decision.

Disciplinary

Prior to taking formal disciplinary action against an employee, employers are advised to address the issue informally, although they can initiate the disciplinary procedure straight away if there are grounds to do so. Disciplinary action is justified whenever an employee fails to comply with written standards at work, whether they are related to performance, professional conduct, or relationships with managers and / or colleagues.

Disciplinary procedures usually consist of 3 stages:

There are a few things that must be clearly stated during the disciplinary process in to comply with fair workplace dispute resolution guidelines and to avoid later legal claims about unfair dismissal. These include:

Employment Tribunals

Employment tribunals are a workplace dispute resolution option that can be used if the parties involved in a dispute cannot reach an agreement. Typical cases brought before employment tribunals involve matters like workplace discrimination, unfair dismissals, and other forms of unlawful actions or practices. In most cases, claims have to be made within 3 months of the date in which the problem in question arose, and ACAS must be notified of all claims sent to an employment tribunal.

A fee applies to all cases brought to a tribunal, and is usually split into a claim fee and a hearing fee. Fees must be paid in advance. Some claims can be filed online.
