Why Vietnamese Staff May Not Respond and How to Support Workplace Retention

Quick answer: What should you do when Vietnamese staff do not respond?

A lack of response can stem from several reasons: instructions that are too long, unclear intent behind a question, or fear of making a mistake and speaking up. State briefly by when, what, and to what standard, then have the person explain it in their own words so you can correct gaps in understanding without blame.

Managers who hire Vietnamese staff repeatedly report issues such as “no response even after giving instructions,” “they say ‘yes’ but do not act,” and “they do not speak up even when something is wrong.” Facing these situations, many conclude that the person lacks motivation or communication skills—but the reality is quite different. Vietnam has a communication culture fundamentally different from Japan’s, and responding without understanding that background can pile up misunderstandings and lead to turnover.

This article carefully explains, from Vietnamese cultural and social context, why Vietnamese staff may seem not to respond or to give vague replies, and presents concrete measures that support workplace retention. Building shared understanding among recruiters, frontline supervisors, and leadership is the first step toward long-term retention of Vietnamese talent.

Why they “do not respond”: Differences in communication structure between Vietnam and Japan

In Japanese workplaces, the baseline is two-way exchange: when a supervisor gives instructions, the subordinate clearly replies “Yes, understood,” and asks questions on the spot if anything is unclear. In Vietnam, however, communication norms within hierarchical relationships differ significantly from those in Japan.

Vietnamese society retains a strong Confucian sense of hierarchy, and disagreeing with or questioning a superior can be seen as “rude” or as “exposing a lack of ability.” In other words, when receiving instructions from a supervisor, answering “yes (dạ)” even if the content is not fully understood is considered polite. This “yes” is closer to a signal of “I am listening carefully and showing respect” than to “I understand and agree.”

Furthermore, responding itself is closely tied to “face” (mentsu). The concept of face expressed in Vietnamese as “mặt mũi (mat mui)” means social standing and honor in human relationships, and fear of losing it affects behavior overall. Saying “I don’t understand” or “Please explain again” can, in some cases, be seen as damaging face, and people are especially reluctant to say so in front of colleagues or seniors at work.

In addition, in Vietnam “silence” functions as part of communication. Japan has the idea of tacit understanding (ishin-denshin), but in Vietnam dependence on ambiguous expression and nonverbal communication is even higher. There are cases where people avoid an explicit “no” and instead show refusal or doubt indirectly by not responding. Reading that in a Japanese business context is difficult for both sides.

Concrete workplace patterns: Three mismatches caused by “yes”

Several typical patterns of mismatch tend to arise between Vietnamese staff and Japanese managers.

They say “yes” but do not act

As noted above, a Vietnamese “yes” is often a signal of attentive listening rather than agreement. When you give instructions and ask “Got it?” they answer “yes,” but in many cases they have not actually understood the procedure or priorities. When this repeats, managers grow distrustful of the staff, while staff fall into a state of “not knowing why they are being scolded.”

Reporting, contacting, and consulting (ho-ren-so) do not come up

The “ho-ren-so” habit that Japanese companies drill into new hires from day one barely exists in Vietnamese workplace culture. In Vietnam, people tend to try to solve problems themselves first, and reporting to a supervisor can be taken as “exposing one’s own failure.” As a result, small troubles may go unreported and escalate into larger problems.

They do not ask questions or take notes

In Japanese workplaces, “listening while taking notes” is considered standard business manners, but this habit is often not established in Vietnam. Likewise, the norm of “ask when you do not understand” varies greatly by classroom and workplace environment. People especially tend to feel embarrassed asking questions in front of a large group, and gaps in understanding may surface only later.

Common field consultations: Real cases HR faces

As common field consultations, hiring-support teams repeatedly receive cases like the following.

Case 1: Work stops even after instructions (manufacturing)

A consultation from a floor leader: “We explained the work procedure at the morning meeting and everyone answered ‘yes,’ but when we checked in the afternoon the procedure was wrong. It did not seem intentional, but we could not understand why.” Investigation showed the morning meeting was held only in Japanese, and staff were responding without fully understanding the content. It is important to recognize that listening ability in Japanese and the understanding needed to perform the work are not the same.

Case 2: Resignation comes as a sudden notice (service industry)

A case such as: “A Vietnamese staff member who had been working energetically until last week suddenly said this week, ‘I will leave at the end of next month.’ There were no prior signs.” Later it became clear that the staff member had held work-related dissatisfaction for months but stayed silent, judging that “speaking up would not change anything” or “speaking up would worsen the relationship.”

Case 3: No replies in the work chat (IT / office roles)

A report such as: “When we post questions in the work group chat, Vietnamese staff often do not reply.” Culturally, Zalo and Facebook Messenger are mainstream communication tools in Vietnam, and familiarity with a given app and norms about feeling obliged to reply differ from those of Japanese people. Agreeing on tool selection and operating rules comes first.

Failure patterns and how to avoid them: Missteps raise turnover

Organizing failure patterns and avoidance measures is extremely important for improving frontline management.

Failure pattern 1: Publicly grilling someone with “Why didn’t you say so?”

When staff fail to report or respond, emotionally confronting them in front of others with “Why didn’t you say so?” often backfires. For Vietnamese staff, being scolded before a large group greatly damages face and further shrinks subsequent communication.

As an avoidance measure, hold post-incident dialogue in a private one-on-one setting, avoid a blaming tone, and focus the discussion on “How can we solve this together next time?”

Failure pattern 2: Ending with only a yes/no check of “Did you understand?”

A situation where the only reply to “Did you understand?” is “yes” is not a real check. Binary (yes/no) questions are especially structured to draw out “yes” in Vietnamese culture.

As an avoidance measure, confirm understanding with open questions such as “Please explain the steps I just taught in your own words” or “What will you do first?” It is also effective to use visualized flow sheets and pictograms for work procedures and reduce dependence on Japanese alone.

Failure pattern 3: Treating Japanese ability alone as the cause of communication problems

Even if you push language learning alone on the assumption that “things will improve once Japanese improves,” differences in cultural communication norms will not disappear. Alongside language acquisition, efforts that promote mutual understanding of cultural background are essential.

As an avoidance measure, run internal cultural training (two-way for the Japanese and Vietnamese sides) and create opportunities to learn from each other “why people act that way.” When needed, using an agency experienced in hiring and retaining international talent is also effective.

Failure pattern 4: Moving ahead without a reply

Sending a message by chat or email and proceeding on the assumption that “they must have understood” when there is no reply risks work advancing without the content actually having been conveyed.

As an avoidance measure, combine oral confirmation for important work communications and, when needed, set up double-checks through interpreters or bilingual staff.

Points recruiters often miss: Pre-acceptance checks shape retention

Among points recruiters often miss, insufficient preparation at the acceptance stage frequently becomes a remote cause of later communication problems.

No orientation on communication style

Many companies invest in legal procedures and job-skill training but do not create explicit opportunities to teach “communication culture in Japanese workplaces.” Even if you say orally, “Please always ask if you do not understand,” many Vietnamese staff will not take that literally. You need to carefully explain, with concrete episodes and examples, “why asking questions matters” and “that this is a culture where asking will not get you scolded.”

Insufficient follow-up interviews within the first three months

Ministry of Health, Labour and Welfare data on foreign employment also show that foreign worker turnover tends to concentrate within six months of starting work. Right after joining, staff are still “watching how things go,” so dissatisfaction rarely surfaces from the staff side. Setting one-on-one interviews at the one-month and three-month marks and building trust is key to raising retention.

Jumping to “no response = no motivation”

When communication issues arise after hiring, concluding they are a “motivation problem” without considering cultural background delays appropriate support. When setting judgment criteria, organizations should put in writing as a rule that they will always consider whether cultural factors underlie the behavior.

Note that communication traits of Southeast Asian talent differ by country. Cultural background specific to Myanmar talent is explained in detail in this article as well; what is common is the importance of consideration for “face” and hierarchical communication. Understanding country-by-country differences and responding individually is required.

Practical checklist: 10 items to improve communication with Vietnamese staff

As a practical checklist, we recommend that accepting-organization contacts regularly confirm the following 10 items. Reviewing monthly or quarterly and visualizing improvement progress supports continuous retention efforts.

Are you using open questions to confirm work instructions?
Are work procedures and manuals prepared in visually understandable formats (diagrams, pictograms, photos)?
Have you scheduled and conducted regular one-on-one meetings (at least once a month)?
Have you explicitly told new hires at onboarding that reporting, contacting, and consulting are “allowed and encouraged” behaviors?
Do you always give reprimands and coaching in a private space?
Have you agreed with staff on rules for work communication tools (such as reply deadlines)?
Have you prepared emergency contacts and internal rule lists that staff can read in their native language (Vietnamese)?
Have you assigned a senior staff member or buddy who speaks Vietnamese?
Do you conduct follow-up interviews at 1 month, 3 months, and 6 months after joining?
Do you run internal training or external support on cultural background at least once a year?

Diagram: Pre-hire confirmation flow and retention support steps

Below is a summary of steps companies should confirm from the hiring decision for Vietnamese staff through workplace retention. We recommend using it as internal shared material or onboarding material.

Step 1: Confirm acceptance readiness before hiring

Confirm the type of work authorization and status of residence based on the latest guidelines from the Immigration Services Agency of Japan. For Vietnamese talent, multiple statuses of residence exist—such as Technical Intern Training, Specified Skilled Worker, and Engineer/Specialist in Humanities/International Services—each with a different permitted scope of work. Also confirm whether internal manuals can be provided in Vietnamese and whether a buddy (a senior staff member of the same nationality) is available.

Step 2: Onboarding orientation

On day one, carefully explain Japanese workplace communication culture (the purpose of ho-ren-so, encouragement to ask questions, and how to receive feedback). Distribute Vietnamese versions of internal rules and emergency contacts, and present work flows in visual form.

Step 3: Follow-up in months 1–3 after joining

Build trust through monthly one-on-one meetings. Confirm work understanding with open questions and aim for early detection of workplace communication issues. Whether staff come to see managers as “people they can approach” depends on the quality of dialogue in this period—and that is the watershed for retention.

Step 4: Retention phase from six months to one year

Share career paths and set individual goals, and present concrete benefits of staying medium to long term. Pair Japanese skill-up support (such as subsidies for external Japanese classes) with two-way cultural training.

By embedding this flow in the organization, many “no response” problems can be prevented before they arise.

The direction of foreign worker support indicated by law and government

Regarding acceptance of foreign workers, the Ministry of Health, Labour and Welfare and the Immigration Services Agency of Japan publish various guidelines and support resources.

The Ministry of Health, Labour and Welfare publishes the “Guidelines for Employers to Appropriately Deal with Improvements in Employment Management of Foreign Workers,” which expressly lists communication support and consultation systems as employer responsibilities. Hello Work also provides job-support counters dedicated to foreign nationals, where company contacts can consult on hiring and retention.

The Immigration Services Agency of Japan continuously updates the latest information on types, requirements, and procedures for statuses of residence on its official site. Because legal amendments and system changes occur frequently, it is important for responsible staff to make a habit of checking regularly. In addition, e-Gov provides direct access to the original text of laws such as the Immigration Control and Refugee Recognition Act, so it can be used when confirming legal grounds.

Frequently asked questions (FAQ)

Q1. Do Vietnamese staff “not respond” because they are weak in Japanese?

It can happen when Japanese ability is low, but similar issues also arise with staff who are relatively fluent in Japanese. Cultural background—face, hierarchical communication, and reliance on nonverbal communication—is often the main cause, so alongside language learning you need efforts that deepen mutual understanding of cultural communication norms.

Q2. Can you establish ho-ren-so among Vietnamese staff?

Yes, it is possible. However, it is important to carefully explain why ho-ren-so is necessary and to give positive feedback such as “Thank you, that helped” when staff actually report or consult. If they have even once been strongly scolded or coldly brushed off when reporting, subsequent reporting behavior drops significantly. Building psychological safety is a prerequisite.

Q3. How can you avoid taking “yes” to mean “I understand”?

Changing how you confirm understanding is most effective. Instead of “Do you understand?”, use open questions such as “Could you repeat what I just explained?” or “What is the first step?” It is also effective to hand over work procedures as a visual flow sheet and confirm along those steps.

Q4. What should you do when only Vietnamese staff do not reply to work chat messages?

First, it is important to agree in advance on the communication tools to use and the reply rules (for example, reply within a certain number of hours). In Vietnam, people are highly familiar with Zalo and Facebook Messenger, so deciding on tools and operating rules together with staff also helps build relationships.

Q5. Are there signs you can notice before Vietnamese staff suddenly resign?

Common signs include: (1) a sudden drop in how much they speak, (2) long conversations with same-nationality colleagues during breaks (often sharing job-change information), (3) increased use of paid leave, and (4) a decline in care taken with work. Continuing regular one-on-one meetings makes it easier to detect these changes early.

---

Behind the sense that Vietnamese staff “do not respond” lie deep Vietnam-specific cultural factors such as face, hierarchical awareness, and reliance on nonverbal communication. Misreading this as a “motivation problem” or a “personality problem” damages mutual trust and ultimately shows up as resignation. Updating judgment criteria based on cultural context and systematically carrying out pre-acceptance preparation, onboarding orientation, and post-hire follow-up is the key to genuine performance and long-term retention of Vietnamese talent.

Frequently asked questions about Vietnamese staff responses and listening

Why do Vietnamese people seem not to listen? It is not that they are not listening; in Vietnamese, “yes” is often used as a listening signal rather than agreement. Even when they answer “yes” to instructions, they may not understand the steps or priorities, so switching confirmation from “Got it?” to having them restate in their own words surfaces gaps on the spot. What should you do when they say “yes” but do not act? Break down “by when, what, and to what state” into short sentences, and at the end have them explain the steps back to you. Avoid giving multiple instructions at once; confirm completion one by one so alignment is traceable. Why don’t reports or consultations come up? Japanese companies’ “ho-ren-so” barely exists in Vietnamese workplace culture, and people tend to try solving problems themselves first. Reporting to a supervisor can also be taken as “exposing one’s own failure,” so codifying when and how to report and evaluating the act of reporting itself improves the situation.
