Highlights
| Completing right to work checks confirms legal compliance when employing foreign workers, but it isn’t where an employer’s obligations end. Under UK and Irish health and safety law, safety instructions and emergency procedures must be genuinely understood by every worker, not just issued. Where language barriers prevent that, compliance and safety risks follow, regardless of which side of the border your business sits on. |
For most HR professionals and operations managers employing foreign workers in the UK or Ireland follows a familiar, rigid routine. You complete your right to work checks, a passport and share code in the UK, an Irish Residence Permit or employment permit in Ireland, log the document, and clear the file.
Right to work checks only help us confirm that someone is legally permitted to take a job. It says nothing about whether they can safely read a chemical safety data sheet, follow a rapid instruction on a busy loading bay, or accurately complete a handover shift log. That responsibility sits elsewhere, and in both jurisdictions, the law is explicit about it.
Where Right to Work Ends and Health & Safety Begins
United Kingdom
Under Section 2 of the Health and Safety at Work etc. Act 1974, employers must provide “such information, instruction, training and supervision as is necessary to ensure, so far as is reasonably practicable, the health and safety at work of his employees.”
The HSE’s dedicated guidance for employers of migrant workers is explicit that this duty isn’t met by issuing a translated poster or running a standard induction. It instructs employers to plan induction training in plain, simple language, check that workers fully understand the risks and precautions involved, and confirm they can communicate effectively with supervisors.
Ireland
The equivalent Irish duty, under the Safety, Health and Welfare at Work Act 2005, goes further than the UK’s in one respect: it names the language requirement directly. The Act requires that “all instruction, training and supervision is provided in a manner, form and language that is reasonably likely to be understood,” and that employee training take account of “the employee’s capabilities in relation to safety, health and welfare.” The Health and Safety Authority enforces this and can issue Improvement or Prohibition Notices where it isn’t met.
In both jurisdictions, the same gaps show up in practice:
- Informed Understanding vs. Passive Assent: Nodding along during a safety briefing is not proof of comprehension. If a worker signs an induction form without fully grasping the safety protocols, the employer remains liable if an incident occurs.
- Dynamic Risk Assessments: On a fast-moving production line or haulage site, hazards change constantly. Staff must be able to comprehend live verbal warnings, call out equipment faults, and report near-misses immediately.
- Emergency Procedures: During an evacuation, severe weather event, or machinery failure, critical instructions are delivered rapidly in spoken English. Partial understanding in a high-stress moment creates severe safety risks.
Simply put, you cannot contract out or delegate your health and safety obligations behind a completed right to work document.
The Legal and Operational Costs of Communication Gaps
When language barriers in the workplace go unaddressed, the impact spreads beyond safety metrics into core HR and operational performance.
Equality and fair treatment
Language itself isn’t a protected characteristic in either jurisdiction, but requiring a level of English fluency that isn’t genuinely necessary for the role can amount to indirect discrimination, because it disproportionately disadvantages people of a particular nationality. In the UK, this falls under the Equality Act 2010; in Ireland, under the Employment Equality Acts 1998–2015, enforced by the Workplace Relations Commission. In both systems, a blanket “must speak fluent English” requirement needs to be objectively justified by the actual demands of the role (a defensible position for a safety-critical task, a harder one to defend uniformly across an entire site).
Operational efficiency and rework
Beyond legal exposure, communication gaps carry daily financial costs. Misread pick sheets in warehouses lead to dispatch errors. Misunderstood standard operating procedures on manufacturing lines cause product defects, equipment downtime, and wasted materials.
Staff retention and integration
Workers who feel isolated by language barriers leave sooner. High staff turnover among migrant workers is rarely due to a lack of practical skill; more often it’s the frustration of being unable to communicate with supervisors, understand shift rotas, or express career ambitions.
Bridging the Gap: What Employers Should Do Next
Addressing this doesn’t require turning operational managers into language teachers, or relying indefinitely on informal, peer-to-peer translation on the shop floor. Asking bilingual co-workers to translate complex safety instructions introduces inaccuracy, burdens productive staff, and masks the true level of risk on site.
A structured approach focuses on the functional terminology your site actually needs:
- Conduct a communication risk audit. Identify where written and spoken English directly affects safety and output permit-to-work sign-offs, handover logs, machinery operation.
- Build sector-specific language training, tailored to your site’s SOPs, safety terms, equipment manuals, and the real communication needs of your employees.
- Use funded routes where available. In Great Britain, that includes Skills Bootcamps; in Northern Ireland, Invest NI’s training grants; in the Republic, Skillnet Ireland can co-fund exactly this kind of workplace-specific training.
Not sure which funding route fits your team? Get in touch and we’ll help you figure it out.
At Everywhere English, we work with HR and operations leaders across manufacturing, logistics, pharmaceuticals, customer service,and healthcare, in Northern Ireland, Ireland and Great Britain, to deliver flexible, job-specific English training built around real safety documents, real shift handovers and real equipment manuals, not generic conversation practice.
