Recruiting and developing employees who stammer (employer booklet)

This booklet is a best-practice guide for human resource/personnel departments and line managers.


The benefits of helping to develop people who stammer include:

  • The person can become more confident to contribute and develop their skills and knowledge
  • Better team communication
  • Better team performance

People who stammer:

  • Can succeed in management, sales, customer service, air-traffic control and a wide range of other jobs
  • Can contribute a greater awareness of communication issues to the workplace
  • Can have excellent listening skills
  • Can understand the value of preparation for presentations and meetings
  • Can have the resolve gained from working to overcome difficulties
  • Can send out a clear message that your organisation accepts people on merit and is disability-aware.

People who stammer: Some Facts


  • Stammering (also called stuttering) is a speech/fluency difficulty where the person has speech blocks (getting stuck on one sound; a silent block is when nothing comes out at all), prolongations (stretching sounds out), or repetitions of sounds.
  • It is individual. Each person stammers differently, and this can vary from one day or situation to another. The person may also avoid words and situations because of anxiety and strong feelings about their stammering.
  • It does not result from a personality or intellectual disorder. People who stammer tend to have normal intelligence, competence and ability.
  • People who stammer know what they want to say but sometimes find it difficult to physically produce speech.

Your patience and active listening are very helpful for people who stammer.


Current research suggests it has a physiological basis in the workings of the brain, but the cause is not known. While stammering can cause people to be nervous about speaking, stammering is not caused by nervousness or uncertainty.


Tiredness, time pressure or anxiety can make stammering worse. It is rare to completely lose a stammer.

Using the telephone, interviews, presentations and meetings can be more difficult, particularly when there is pressure to speak.


One percent of adults in the UK stammer. Men are four times more likely to be affected than women.


When meeting a person who stammers, stay focused on what the person is saying about their experience, abilities and skills. It is normal to feel some anxiety or embarrassment, when listening to someone who stammers, so concentrating on what the person is saying can be a good way to deal with this.

As with most people, a job interview can be a very difficult speaking situation. Stammering may be at its most severe, particularly when the person is enthusiastic about the position they are being interviewed for.

Not all aspects of stammering are obvious. The person may come across as hesitant or confused, pausing before words and/or using phrases such as "you know", "well actually", "it could be said". These may be strategies to avoid stammering.

Some people who stammer have found it helps if listeners do the following:

  • Listen attentively and wait for the person to finish. Do not try to finish their words or sentences
  • Speak normally in a relaxed manner, even if you are feeling uneasy
  • Try to maintain natural eye contact with a relaxed posture
  • Don't equate hesitant speech with uncertainty
  • If the person mentions their stammer, they will be more open to discussing it.

(Interviewers will,though, want to bear in mind the restrictions on pre-employment enquiries about disability under the Equality Act 2010.)


Always look at the person, not at assumptions you may have about them.

On the Job

When the person begins the job, introducing them to colleagues and managers can be a valuable way to break the ice. Try to show support by having an open-door approach. Stammering can be a sensitive personal issue that some people may not want to discuss. You may also find it difficult to discuss something you know little about.

Talk to your employee and encourage training and work opportunities in areas in which they may have excellent skills, but may have previously avoided. When the person feels confident about being open, stammering can become much less of a concern.

Case study:

"We didn't dodge the issue by ignoring it - we talked about it, and I did it light-heartedly, maybe that was my way of coping."
A manager at British Aerospace Systems

People who stammer may hold back from speaking due to:

  • Fear of a 'classroom' situation in meetings
  • Fear of stammering when speaking in groups and giving presentations
  • Lack of understanding of their stammering problem by managers, colleagues and course leaders
  • Difficulties with using the telephone.

When speaking with a person who stammers:

  • Show patience and active listening by focussing on what the person is saying
  • Give the person more time to deal with any stammering
  • Stammering varies widely, so don't be put off if the person stammers when you would not expect them to
  • If you begin group meetings by having colleagues introduce themselves, ask the person who stammers to go first or second. This will prevent anxiety building while they wait for their turn
  • On the telephone, please DO NOT hang up if you hear a few moments silence, and avoid negative impressions of a person based on the way they sound
  • If it seems appropriate, ask the person about how best to respond when they stammer

People who stammer say:

"My stammer hasn't stopped me taking public meetings and giving evidence to planning enquiries. People may be surprised, but they bear with me and it doesn't stop me from communicating effectively."

"By making it clear to me that I would not be penalised as a result of stammering, I became more comfortable in the work environment."

Training and personal development:

  • Encourage the person to develop their confidence and take on challenges which will benefit their speech, without pushing the person too far
  • Demonstrate your support by discussing with the person things they would like to achieve, and their successes and difficulties
  • Personal development and performance plans could include goals for important communication skills, in agreement with the employee. Agree on tasks that can be monitored, for example, talking at meetings, greeting clients and company visitors, and giving external presentations
  • Consider sponsoring an employee on a speech or personal development course as part of their training. If you are both comfortable with talking about stammering, you may want to discuss this with the person. Courses often result in long-term gains in communication skills and confidence
  • Promotion and responsibility depend more on the person's skills and experience than on fluency.

People who stammer can make valuable contributions to a workplace through their awareness of communication. Focussed listening, clear thinking, approachability and an interest in people are qualities that do not depend on fluent speech, and may even be enhanced in people who stammer.


Ask the person about what they want to contribute to a job and about any concerns they may have

Case study:

John works as an administrator for AWE. "His self nomination for this [speech] course was supported as part of his personal development plan and, as a key player in a busy office, the course offered potential to improve both his confidence and fluency. The investment was rewarded with an immediate and significant positive change. John was much more relaxed and assured in his speech, and competence has been sustained through a programme of continuous personal development. He is now able to successfully take on challenges which have revealed an intuitive understanding about communications that is the envy of colleagues. This course was pivotal in giving access to a talent with wide reaching benefits to AWE and the wider community. Without it, we may have lost a great opportunity!"
Ian Bowes, Director Human Resources and Strategic Development, AWE Aldermaston

The Equality Act 2010

Stammering can be a disability under the Equality Act. Discriminating against a person in relation to a stammer may be unlawful and the Act may require you to make some adjustments.

Some people who stammer do not consider themselves disabled, so you may want to mention these adjustments without reference to stammering as a disability.

Specific adjustments should normally be discussed with the person who stammers. Examples of reasonable adjustments could include:

  • Allowing more time, if necessary, at interviews/presentations and oral assessments. (This, and written responses/alternatives as mentioned below, are best done through a prior arrangement)
  • Greater consideration given to a job applicant's written information (to supplement spoken answers, which may be limited) or, where appropriate, allowing written responses to interview questions and/or written alternatives to oral tests or presentations
  • Ensuring the person has an opportunity to have their say at meetings
  • Ensuring the person has adequate support and preparation when giving presentations
  • Negotiating arrangements for telephone calls if they are a problem, for example allowing flexibility with a set script of words, and making available a quiet place for calls where the person does not feel overheard.

Problems with speech during an interview are not a reliable indication of how speech will be in the job, even in what might be seen as more 'difficult' or stressful job situations.

Access to Work grants can be available for altered auditory feedback devices, which help some people who stammer.
