Demand for English as a Second Language (ESL) classes has grown in recent years, driven in part by workforce necessity. English is the dominant language in most American workplaces, making proficiency important for job seekers and employees hoping to advance in their careers.

There are numerous success stories from ESL learners about how they’ve overcome language barriers and achieved great success. However, when employees are still developing their English proficiency, there are challenges that can affect the entire workplace.

If you employ ESL learners, you have a role in recognizing these barriers and creating an environment where they feel supported instead of embarrassed or self-conscious as they continue learning.

In this article, the ESL staff at Workforce Essentials explain the most common challenges ESL learners face at work and practical ways employers can better support them.

Common Challenges ESL Learners Face on the Job

Learning English in a classroom, practicing at home or in everyday life, and using it throughout a workday are very different experiences. At work, English learners face unique barriers, including unfamiliar words and industry terminology, cultural differences, and a lack of confidence to speak up or ask for clarification.

Workplace Language and Communication Barriers

Learning a new language involves more than knowing what words mean or how to say them. ESL learners are also learning how words fit together, proper grammar and phrasing, and how to understand different accents, speaking speeds, slang, and other nuances of everyday conversation.

All of that can make communication challenging in any setting, but the workplace often adds another layer with job-specific terminology, abbreviations, written instructions, and conversations that require employees to understand and respond in real time.

Some of the ways these communication barriers can show up on the job include:

  • Keeping up with fast-moving conversations: Team meetings, shift changes, customer interactions, or group conversations can make it difficult to process information quickly enough to follow everything being said.
  • Interpreting workplace phrases correctly: Idioms, slang, shorthand, and phrases such as “touch base” or “circle back” can be confusing because their intended meaning is different from the literal meaning of the words.
  • Understanding written workplace communication: Emails, training materials, signs, safety instructions, and procedures may include unfamiliar vocabulary, abbreviations, or more complex sentence structures.
  • Learning the language of a specific job or industry: Technical terms, acronyms, equipment names, and other job-specific vocabulary create another layer of language employees may need to learn before they can communicate confidently in their role.

Employers should understand that these challenges may not reflect an employee’s intelligence, ability, or work ethic. An ESL employee may know the job but still need extra time, context, or clarification to fully understand what’s being communicated.

Confidence and Cultural Barriers That Go Beyond Language

When an ESL employee struggles to understand and communicate, it can create a domino effect beyond the language barrier itself. They may become less confident speaking up, asking questions, joining conversations, or interacting with coworkers due to fear of saying the wrong thing or being misunderstood.

Over time, hesitation can make an employee seem withdrawn or less engaged, even if that is not the case. It can also hinder the development and use of important workplace soft skills, which are as important as technical skills.

Cultural differences can add communication challenges. In some cultures, questioning a supervisor, asking for clarification, or admitting confusion is seen as disrespectful. If this mindset carries into the workplace, an employee may stay quiet, avoid participating in problem-solving, or hesitate to share concerns or ideas.

Employers and coworkers may mistake these hesitations for disinterest or lack of effort, even though they may simply stem from communication habits shaped by upbringing or past experiences.

Employers should recognize that a quiet or hesitant ESL employee may still be adjusting to workplace communication. Encouraging questions, requests for clarification, and participation helps ESL learners know that speaking up is acceptable and supported.

Language Gaps May Affect Accuracy, Safety, and Team Dynamics

If an employee does not fully understand an instruction, procedure, or expectation due to a language barrier, they may miss an important step, complete a task incorrectly, or miscommunicate with a coworker. This could cause something as simple as a missed deadline or work that needs to be redone, but it could also contribute to more serious issues involving workplace safety, operational costs, or team morale.

Accuracy matters in every job. The consequences of an error can vary widely depending on the task, ranging from minor to significant. A misunderstanding may simply require repeating a process, while in other roles it could affect production, cause customer dissatisfaction, increase waste, add labor costs, or raise risk in higher-stakes roles.

Language barriers can also affect team dynamics. Miscommunication can be frustrating for an employee who is learning English and trying to understand expectations. It can also cause stress for coworkers if they have to repeat instructions, correct errors, or take on extra tasks. If these situations happen repeatedly, tension can build on both sides and affect collaboration and morale.

The most serious concerns arise when an employee does not fully understand information that affects safety. Warnings, equipment instructions, emergency procedures, safety policies, and changes in protocol should always be communicated in a way employees can fully understand.

Employers should be aware when an employee’s English proficiency may not be strong enough to understand critical safety information. While employers are not generally required to conduct all workplace communication in a worker’s preferred language, OSHA requires that safety training be presented in language and vocabulary workers understand. If an employee is not fluent in English, you must offer it in their native language.

How Employers Can Help ESL Employees Succeed

Employers cannot remove every challenge of learning and using a second language at work, but they can make communication easier and create an environment where ESL employees feel more comfortable asking questions, requesting clarification, and participating without fear of embarrassment.

Sometimes informal workplace support, like changing how instructions are given, is enough. Other times, structured support such as formal ESL classes or employer-sponsored language training is necessary.

Simplify and Visualize Instructions for ESL Learners

One of the easiest ways employers can help ESL employees understand instructions is to slow down and make communication clear, simple, and direct.

When possible:

  • Use clear, plain language: Keep instructions concise and avoid unnecessary jargon, slang, idioms, or complicated phrasing.
  • Show rather than only tell: Demonstrate a task in person or use photos, diagrams, videos, or other visuals to reinforce verbal or written instructions.
  • Break complicated tasks into steps: Giving instructions in a logical sequence can make them easier to understand, remember, and follow.
  • Provide important information in writing: Written instructions give employees something they can review again if they do not catch everything the first time.
  • Confirm understanding: Instead of just asking, “Do you understand?” give employees a chance to repeat instructions or demonstrate the task so confusion can be cleared up before mistakes happen.

Using multiple ways to communicate the same information can help ESL learners understand expectations while they continue building their English skills.

Be Patient with ESL Employees and Encourage Peer Support

Learning to communicate confidently in a second language isn’t easy and takes time. How coworkers and supervisors respond can either make this process easier or create unnecessary tension. The goal is to create a workplace where asking questions, helping one another, and taking the time to communicate clearly are part of your culture.

A little patience goes a long way in helping employees build the confidence they need to succeed. Employers and supervisors should offer reassurance when an ESL employee needs an instruction repeated, asks for clarification, or takes longer to respond, and encourage their employees to do the same. An impatient tone or visible frustration can make someone less likely to ask questions the next time, increasing the chance that a misunderstanding goes unaddressed.

Creating opportunities for peer support is also an excellent way for team members to improve communication and improve team dynamics. Pairing an ESL employee with a patient coworker, bilingual team member, or mentor gives ESL learners someone they feel comfortable turning to with questions as they continue learning the job and the language.

Recognize When Formal ESL Training Is the Right Next Step

If language barriers repeatedly affect communication, job performance, safety, team dynamics, or an employee’s ability to advance, formal ESL support may be the next step.

Structured programs are designed to help employees build language skills more systematically while giving employers a more effective long-term way to address communication gaps than repeatedly working around them.

FAQ

Are employers required to provide language support for ESL employees?

In some cases, yes. For example, OSHA requires that employee safety training be presented using language and vocabulary workers can understand. If an employee does not understand English, required training must be provided in a language they do understand. Other requirements may vary depending on the job, industry, and circumstances.

Is it legal to require English fluency for a job?

It can be. Employers may require a certain level of English proficiency when it is necessary for effective job performance. However, a fluency requirement that is not genuinely related to the job may raise concerns about discrimination. Employers should make sure any language requirement is tied to the actual duties of the position and seek legal or HR guidance when needed.

What should I do if a language barrier is causing tension between coworkers?

Address it directly and early rather than letting frustration build. A private conversation with the employees involved can help determine whether the issue is a communication problem rather than a personality conflict. From there, practical steps such as clearer instructions, written follow-ups, or peer support may help reduce misunderstandings and improve how the team works together.

ESL Programs at Workforce Essentials

If you own a business, an applicant not being fluent in English shouldn’t take them out of consideration for a job they are otherwise qualified to do. Bilingual and multilingual employees can bring valuable language skills and cultural knowledge to a workforce.

In fact, ACTFL found that 9 in 10 surveyed U.S. employers rely on employees with language skills other than English, and 56% anticipated increased demand for those skills. Additionally, as ESL learners continue building their language skills, those improvements can open doors to new roles and career advancement within your company, a topic we cover in more detail in From ESL Classroom to Career Advancement.

That said, hiring someone who is still developing their English proficiency may require additional patience and, in some cases, outside support to properly bridge an English language gap in the workplace.
