Mediation is the process in which a mediator facilitates communication and negotiation between parties to assist them in reaching a voluntary agreement. Mediation is often referred to as ADR – alternative dispute resolution. For Nicole van Gelder the “A “ stands for: “Appropriate”.

The mediation proces

  • First the mediator explains the mediation process and the importance of the confidentiality of the process. Then both parties confirm their willingness to proceed.
  • The mediation process then starts formally by signing the mediation agreement
  • The mediator guides the exchange of all required information and communication between parties and leaves room for their emotions, demands, needs, wishes and desires.
  • Differences and similarities are established.
  • Next, both parties work towards identifying their general and shared interests.In reality, there are always shared interests.
  •  The various options for resolution are exploredand secured according to SMART criteria.
  • When both parties agree on a mutually agreeable resolution, a settlement is made.
  • With this, the mediation is complete.
  • A mediation takes around 8 to 14 hours on average

Dispute resolution

Work disputes are conflicts between the employer and employee, or between individual colleagues. There are various reasons why work disputes arise and escale, for example disagreements regarding collaboration, working conditions and/or performance. Work disputes can have far-reaching consequences for an organization, a team, and for individual employees.

Mediation can help improve work relations and can establish better work agreements. Both parties might also reach the decision to part. The mediator can guide them do so on good terms. The mediator identifies and discusses the wishes and possibilities with both parties in order to reach the best possible solution for all involved. This is done in a neutral, professional manner, while leaving room for the various emotions that can arise in these situations.

Advantages of dispute resolution

An average work dispute can cost an organization around €31,087. Mediation can lower these costs to €3,137.

Business Mediation

Business conflicts can arise between companies, business partners, directors, board members associates etcetera. For example over a breach of contract or a dispute over undelivered services, at least according to one of the parties. Normally both parties will go to court. A specialized mediator and dealmaker can not only limit the costs of these procedures, but can also help find a solution that doesn’t damage the parties’ mutual relationship. Sometimes such a solution can even be mutually beneficial.

Advantages of business mediation

Did you know that a standard €200,000 trade dispute can cost around €32,000 in legal fees and take up to 700 days (2 years)? Mediation can reduce this to 224 days and €23,000, a reduction of 32%.

Dealmaking or deal breaking?

A mediator can be a valuable asset, even when there is no dispute. An experienced mediator can help speed up complex negotiations with multiple parties.

Mediation and the government / Public policy mediation

Because the government is involved with citizens, companies, social organizations and other governments, a good relationship with each of these parties is essential. Public Policy Mediation helps prevent and resolve conflicts.

Governments operate differently than businesses. Governments implement regulations and policies and have a different decision-making process. In addition, other specific characteristics need to be considered when dealing with a government. For example, the Act on Public Access to Government Information, the General Principles for Good Government (ABBB), internal procedures with rigid deadlines and various political sensitivities. By paying attention to these special characteristics, mediation can be a valuable tool in many government cases, resulting in fewer procedures and lower costs.
