Stammering is a speech disorder that affects over 50,000 people in Ireland. This is equivalent to 7–8% of the disabled population¹ and 1% of the overall adult population in the country².

The above is a depiction of nationalist politician Charles Stewart Parnell speaking to the United States Congress in the 1880s. Parnell had an “acute” stammer which affected his ambitions in the public realm³.

What is stammering?

A stammer is the unity of two halves: impediment and disability.

Impediment refers to the actual physical symptoms brought about by neurological differences. These symptoms include repetitions, prolongations, blocks, and in some people, straining and twitching. Each person who stammers (‘PWS’) has a different set of symptoms which can be incredibly variable even within the same individual, changing in character and severity from one sentence to the next. Currently, conventional speech therapy has a two-thirds relapse rate, making focus on medical treatment alone futile⁴.

Disability refers to the restrictions imposed on PWS by society, as well as the mental, emotional, and behavioural consequences of those restrictions⁵. A PWS is considered unable to “exercise sovereign control over their body”, causing people to doubt their rationality, competency, and intellect⁶. This translates to reduced earnings⁷; ostracisation from verbally demanding careers like sales, teaching, and law⁸; and higher-than-average rates of social anxiety, depression, and sleep problems⁹.

Above is a video of Portuguese scholar and political figure Joacine Katar Moreira stammering on national television. Her suitability for the post of parliamentarian was doubted due to her speech impediment¹⁰, with some even accusing her of faking it for sympathy votes¹¹.

In law

Stammering is an ‘invisible’ or ‘hidden’ disability – a disability that is not immediately apparent, and largely goes unaddressed. It falls within the “wide and all-encompassing definition” of disability as provided in s. 2 of the Employment Equality Acts 1998–2015¹².

In 2017, the Workplace Relations Commission awarded a rail technician with a stammer €50,000 for “unfair dismissal and disability discrimination, after finding that his employer had failed to discharge its obligation under… s. 16 to make adequate enquiries concerning the impact of his stammer and his ability to do his job”¹³.

s. 16 obliges an employer to recruit, promote, retain, and/or train a PWS if the PWS willingly performs the agreed terms of a post and is fully competent. A PWS is still considered fully competent if they require “special treatment or facilities”, as long as it comes at no significant and unreasonable cost to the employer.

s. 101(b)(c) of the Assisted Decision-Making (Capacity) (Amendment) Act 2022 requires that 6% of public sector employees be people with disabilities. This means that approximately 0.45% of all public sector positions in the Republic should be populated by people who stammer. Unlike other European Union countries, Ireland has no similar private sector quota¹⁴.

Accommodations

Employees, employers, and recruiters alike are under-educated on the topic of invisible disabilities and how to approach them in the workplace. The onus lies on all parties to initiate and maintain conversations about disability in the workplace, including the implementation of accommodations, seven of which are listed below:

1. Allow for in-person interviews and assessments if the individual finds the virtual format more prone to miscommunication.
2. Allow for the use of written communication formats in place or alongside verbal communication where not essential to the role.
3. Where verbal communication is necessary, alleviate time pressure where possible, such as providing an extra time allowance in interviews.
4. Allow the individual to stammer openly, as suppression of stammering leads PWS to “experience significantly higher levels of adverse impact”¹⁵.
5. Train interviewers, recruiters, and key decision-makers on stammering so they do not misinterpret symptoms as intoxication/drunkenness, incompetence, nervousness, or lack of preparation.
6. Permit or provide (if funding allows) assistive speech technologies where the individual finds them helpful.
7. Allow the individual to bypass artificial intelligence (AI) voice systems that do not recognise dysfluent speech.
