Preventing bullying: a 3-level strategy

An increasingly prevalent phenomenon in the workplace, bullying undermines employees' mental health, jeopardises team cohesion and impairs business performance. Yet inaction is still common because of a lack of clear guidelines. Faced with these alarming facts, companies need to adopt a global strategy, combining prevention and training. Aldric Zemmouri, an expert in psychosocial risks and occupational health, sets out a practical action plan to address this major issue.

An increasingly prevalent phenomenon in the workplace, bullying undermines employees' mental health, jeopardises team cohesion and impairs business performance.

These situations are often insidious. They can arise from dysfunctional working relationships, poorly managed conflicts or unsuitable management. The consequences are serious. Not only for the victims: chronic stress, loss of confidence, isolation, even depression. But also for the company: disengagement of teams, increased absenteeism and staff turnover, and damage to the company's image.

Faced with this challenge, companies can no longer be satisfied with reactive crisis management. A a global, proactive approach is essential for prevent toxic behaviour.

However, recent data show that the subject is still poorly understood in the field. According to the Ipsos x Qualisocial 2022 barometer :

  • 74 % of employees believe that bullying is widespread
  • 62 % perceive an increase in cases
  • paradoxically, 86 % say they are poorly informed about what it actually covers
  • 73 % find it difficult to identify situations of harassment

A training strategy to enhance the skills of key players

This twofold observation - an increase in harassment and a lack of awareness of the phenomenon - calls on most employers to take action. However, it's not as simple as all that to raise the skills of your workforce on these issues. There are many obstacles to overcome:

  • the subjective and invisible nature of damaged relationships
  • a strict legal framework that leaves plenty of room for interpretation
  • internal resistance because it is an anxiety-provoking subject for employees
  • difficulties in changing practices...

These are all obstacles that require employers to implement a genuine training strategy to develop the skills of all the key players involved in dealing with relational violence.

But to be effective, training must be part of an overall plan to prevent bullying and harassment. The plan has three levels of action:

A 3-level bullying prevention plan

1er level of action: the company's common framework for action

To put in place an effective policy to prevent bullying, it is essential to define a clear common framework for action that is shared by all the professionals involved in dealing with these situations. The first step is to define precisely the role of each person involved. Then concrete tools need to be developed, such as reporting and investigation procedures, a list of resource persons and a whistleblowing circuit. 

However, this stage cannot be implemented without first training the key players:

  • human resources (the HR Director and his teams)
  • members of the Social and Economic Committee (CSE) and/or members of the Health, Safety and Working Conditions Committee (CSSCT)
  • management (members of the COMEX/CODIR), which is responsible for this prevention policy

Together, they will have to think about the practical implementation of this policy to prevent bullying.

This training stage is all the more necessary for an employer who has never worked on these issues and whose prevention culture is weak.

Prior training for these players ensures that they have the same level of information (on the legal framework, recommendations, recognised practices, etc.) and a common language. These are essential prerequisites for building a shared framework for action.

2th action level: support for managers

Once the common framework for action has been defined, the next step is to pass it on to all the company's managers.

Indeed, managers are going to be the relays on the ground of the prevention policy driven by management, HR and staff representatives.

But putting this policy of preventing bullying into practice on a day-to-day basis is not so simple. There are several reasons for this. Firstly, a lack of awareness of the phenomenon of bullying makes it difficult to spot at an early stage. In reality, many weak signals (the sidelining of a team member, an inequitable distribution of work between employees, old unresolved conflicts, disparaging rumours or jibes at a single person, etc.) are not seen or interpreted as worrying. What's more, relationship problems between employees are often played down, leaving situations to fester. And even when managers do spot problematic situations, they don't always report them or report them far too late, often because they lack the time or skills to investigate borderline situations further.

Training managers is therefore essential if the policy of preventing bullying is to be put into practice on the ground. This is the ideal time to help them identify the main obstacles that prevent them from raising the alarm. Discussions will often lead to clarification:

  • the alert circuit
  • essential information to be provided
  • documents to be used
  • the vocabulary to use...

The training reinforces the manager's role as guarantor of employee safety and helps him or her to manage potential risks on a day-to-day basis.

3th action level: raising employee awareness

Once the common framework for action has been shared with managers, the company can finally communicate the main elements of its bullying prevention policy to all employees. To do this, it must mobilise all the channels at its disposal:

  • presentation to the CSE/CSSCT
  • regulatory signage
  • internal communication tools (intranet, newsletter, etc.)
  • direct awareness-raising initiatives (webinars, practical workshops, prevention stands)

This is when training for all employees takes on its full meaning. These are usually half-day awareness-raising workshops. What are the objectives?

1/ Raising awareness of the phenomenon itself. This provides an opportunity to clarify the difference between a conflictor harassment. Employees often ask these questions.

2/ Present or reiterate the employer's policy: alert circuit, investigation procedure and care for victims.

The many exchanges with employees during the workshops ensure that the prevention message is well understood and that the tools proposed are operational.

To sum up, preventing bullying requires a strong commitment and a structured strategy involving everyone in the company. Training, awareness-raising and a clear framework are the pillars of a culture where everyone knows how to spot, report and take action. As well as ensuring legal compliance, this is an essential lever for collective well-being and performance. So, beyond moral harassment, isn't the issue more global, or how to establish a corporate culture based on respect, listening and conflict prevention?
