Labor Disputes: What Should an Employer Do When an Employee Files a Complaint with the Labor Department? Is It Necessary for the Employer to Attend and Provide an Explanation in Person?

Labor disputes are one of the most significant risks faced by business owners and employers, regardless of whether they operate a small business, a medium-sized enterprise, or a large organization. Even with careful management, disagreements between employers and employees can arise at any time.

When a dispute occurs, one of the most common ways employees seek to enforce their rights is by filing a complaint with the Department of Labour Protection and Welfare, commonly referred to as “filing a complaint with the Labor Department.”

However, once an employer receives a summons or notice from a Labor Inspector, what steps should be taken? Is the employer required to appear and provide explanations in person? If attending is inconvenient, are there alternative options available? This article from Wongsakorn Law Firm provides the answers.

What Happens When an Employee Files a Complaint with the Labor Department?

When a complaint relating to labor rights is filed, a Labor Inspector will review the facts of the case and may issue a notice requiring the employer to provide an explanation or submit relevant documents for consideration.

Common complaints include:

  • Unpaid wages
  • Overtime pay (OT)
  • Severance pay upon termination
  • Special compensation
  • Leave and holiday entitlements
  • Unfair dismissal
  • Employee rights and benefits under labor law

Upon receiving a notice from the Labor Inspector, employers should not ignore or overlook it, as doing so may affect the consideration of the facts and their legal rights at a later stage.

If the Employer Is Unable to Attend, Can a Lawyer Be Authorized to Act on Their Behalf?

One of the most common misconceptions is that once an employee files a complaint and specifies the amount they are seeking, the employer is automatically required to pay the full amount claimed.

In reality, an employee’s claim is merely an initial allegation or demand.

The relevant authorities will consider:

  • The facts of the particular case
  • Documentary evidence
  • The employment agreement
  • The company’s rules and regulations
  • Witness testimony and documentary evidence
  • Applicable labor laws

Therefore, the fact that an employee claims a certain amount of money does not necessarily mean that the employer will be liable for that amount. If there are facts or evidence showing that the employer has complied with the law, the employer has the right to provide explanations and contest the claim.

Why Should Labor Issues Be Addressed from the Beginning?

Based on Wongsakorn Law Firm’s experience in providing labor law consultation, many organizations only seek legal assistance after a dispute has already arisen.

In reality, most labor-related problems can be prevented before they occur through the implementation of proper labor law compliance and internal employment systems.

Examples include:

  • Preparing comprehensive employment agreements
  • Establishing workplace rules and regulations
  • Implementing employee disciplinary policies
  • Managing leave and holiday entitlements properly
  • Ensuring accurate payment of wages and overtime compensation
  • Establishing legally compliant termination procedures

When an organization has proper systems in place from the outset, the likelihood of labor disputes arising with employees can be significantly reduced.

Why Should Every Organization Have Legal Counsel?

Today, labor laws are becoming increasingly complex and subject to ongoing changes. As a result, personnel management is no longer solely a human resources function, but also a matter that directly affects an organization’s legal risk exposure.

Having legal counsel as part of the organization can help businesses:

  • Prevent problems before disputes arise
  • Review important legal documents
  • Provide legal guidance before making termination decisions
  • Reduce the risk of litigation
  • Establish legally compliant human resource management systems
  • Address other legal issues that may arise in the future

Which is significantly less costly than resolving problems after legal proceedings have already commenced.

“Labor Laws Every Employer Must Know” Wongsakorn Law Firm Conducts Labor Law Seminar for Weilan Optical (Thailand) Co., Ltd.

On May 28, 2026, Wongsakorn Law Firm was honored by Weilan Optical (Thailand) Co., Ltd. to conduct a seminar on the topic “Labor Laws Every Employer Must Know” in order to enhance understanding of Thai labor laws among the company’s executives and employees. This marks another important mission of Wongsakorn Law Firm in its role as legal advisor to the company.

The seminar was led by Lawyer Arm, Supasit Siri, Head of Wongsakorn Law Firm, together with Mr. Kittithat Limtasiri, Chinese-speaking Legal Assistant, and Mr. Thaniphat Manopak, Legal Assistant and HR Officer of Wongsakorn Law Firm. More than 50 participants attended the session, the majority of whom were Chinese executives and employees of the company.

The atmosphere throughout the event was warm and friendly. Weilan Optical (Thailand) Co., Ltd. warmly welcomed the team from Wongsakorn Law Firm and provided opportunities for attendees to ask detailed questions regarding Thai labor laws, including wages, leave entitlements, holidays, employee rights, employer obligations, and other important labor law matters.

The Q&A session was conducted seriously and directly to the point. Wongsakorn Law Firm carefully explained the relevant legal details to ensure that the company gained a clear and accurate understanding, as we fully understand that labor law is a sensitive and highly complex matter, and one of the most common issues faced by organizations of all sizes from small businesses to international corporations.

From the perspective of Lawyer Arm, Supasit Siri, labor and employee-related issues are problems that “never truly disappear” as long as businesses continue to work with people. Every individual has different thoughts, understandings, and behaviors. This is precisely why companies should have a “legal advisor” or “consulting lawyer” involved from the beginning before problems escalate into labor disputes or complaints filed with the Department of Labour Protection and Welfare.

Lawyer Arm Supasit Siri is considered someone with deep understanding of labor law issues because he has previously experienced life as an “employee” himself and currently serves as both a “lawyer” and a “business executive.” This allows him to understand both employer and employee perspectives very well. He has also personally encountered labor-related challenges in the business world and successfully managed such situations appropriately without suffering legal disadvantages or causing reputational damage to the organization.

Therefore, having legal advisors or a labor law legal team is not merely about solving problems after lawsuits arise, but rather about “preventing problems” before they actually happen, something extremely important for organizations in today’s business environment.

Wongsakorn Law Firm is ready to provide labor law consultation services to companies and organizations of all types, including seminars, training programs, and labor law courses for executives, HR departments, and employees.

We believe that “a proper understanding of labor law” is the key starting point for reducing conflicts within organizations and effectively preventing legal problems in the future.

In addition, Lawyer Arm believes that many companies today may still be “violating labor laws without realizing it,” whether due to misunderstandings or lack of proper legal guidance. As a result, many organizations later face problems when employees file complaints with the Labour Protection and Welfare Office.

Do not allow misunderstandings about labor law to become a ticking time bomb waiting to explode, because in reality, Thai labor law always provides greater protection to employees than employers.

 Labor Law Attorney: Summoned by the Department of Labour Protection and Welfare—How Should Employers Respond? Key Labor Law Issues Employers Must Know Before It’s Too Late

A labor law attorney becomes essential when a business starts to grow. Along with business expansion and the core issues employers face, “legal problems” inevitably follow—especially labor law issues, which are among the most common challenges that all business owners, employers, and executives must inevitably encounter.

Many employers or business owners mistakenly believe that:

“If the Department of Labour Protection and Welfare summons us, we can just hire a lawyer at that time.”

In reality, this mindset can place employers at a disadvantage from the very beginning. The core principle of labor law is not to wait until problems arise and then fix them, but to have legal counsel from the outset. In particular, when you are a business owner or employer, starting a company does not only involve revenue or profit. It must be acknowledged that “problems” will inevitably follow—and one of the unavoidable issues is labor-related matters.

What Does It Mean to Be Summoned by the Department of Labour Protection and Welfare?

The Department of Labour Protection and Welfare is responsible for monitoring employers’ compliance with labor law, such as:

  • Wage payment
  • Overtime payment
  • Termination of employment
  • Severance pay
  • Employee welfare arrangements
  • Employment contracts

If employees file complaints or if there is an official inspection, employers may be required to “clarify facts,” which is often when business owners begin to feel alarmed.

Do Not Wait Until You Are Summoned Before Hiring a Lawyer

This is a very common mistake. Many business owners tend to:

  • Ignore employee problems
  • Do nothing when complaints are filed
  • Only seek legal counsel when summoned by the labor office

To be direct, by that point, it is already “too late.” In labor cases and labor law matters, the preparation of information, factual strategy, and documentation can significantly affect the direction of the case. Without proper planning from the beginning, the risk of being placed at a serious disadvantage is extremely high.

How Should You Respond to the Department of Labour Protection and Welfare?

The key principles of response are:

1. Rely on facts
Officers will consider evidence and factual circumstances, not the employer’s feelings.

2. Prepare complete documentation, such as:

  • Employment contracts
  • Company regulations
  • Warning letters
  • Time attendance records
  • Payment evidence

3. Do not respond without legal counsel
This is the most important point. Certain statements may later become evidence used against the company.

Therefore, having a labor law attorney involved from the beginning is essential.

Major Business Problems That Never Disappear

The reality of business is that no business is free from problems.

Common issues include at least five major areas:

1. Labor law issues
This is one of the most common problems employers face, such as:

  • Employee lawsuits or complaints
  • Unfair dismissal claims
  • Severance pay disputes
  • Overtime pay (OT) disputes
  • Leave and tardiness issues

Labor law issues are something every employer will inevitably encounter.

2. Contract issues
Every business involves contracts, such as:

  • Employment contracts
  • Lease agreements
  • Sale and purchase agreements
  • Partnership agreements

If contracts are drafted incorrectly or improperly, problems will inevitably follow.

3. Business partner disputes
Business transactions between companies and their partners often involve disputes regarding payment, product delivery, or breach of contract. This is why businesses should have lawyers draft agreements and legal documents, or review and supervise them from the very beginning. 

4. International business issues
If your business involves international trade or foreign transactions, legal issues become even more complex, such as:

  • Foreign laws
  • Contract enforcement
  • Taxation
  • International disputes

5. Internal management issues
For example:

  • Partnership disputes
  • Profit-sharing conflicts
  • Disagreements in decision-making

All of these involve legal dimensions that may require proper legal consultation and targeted solutions to ensure the business can continue operating smoothly in the future.

Starting a Business = Accepting That Problems Will Follow

This is a reality every business owner must understand. A company is not only about sales and profit—it always comes with legal obligations. In particular, as long as you have employees, labor law issues are unavoidable.

The more employees you have, the more problems may arise.

Employee-Related Problems Have No Fixed Formula Because Every Employee Is Different

For example:

  • Tardiness
  • Absenteeism
  • Refusal to follow instructions
  • Sudden resignation
  • Lawsuits or complaints

The greater the amount of labor, the more complex these problems become.

Perspective from Lawyer Arm Supasit: Having Experienced Both the Roles of “Employee” and “Employer”

From the perspective of Lawyer Arm Supasit Siri, who has been a lawyer, business owner, former employee, and is currently an employer, it must be honestly said that even with a strong understanding of the law, labor law issues are still unavoidable because these problems can arise in every organization.

However, the important thing is that such issues can be successfully managed without being placed at a disadvantage against employees—if proper planning is in place.

Labor Problems Never End, But They Can Be Managed

This is the reality: labor and employment issues never completely disappear, but they can be properly managed through establishing a strong company system from the beginning, preparing accurate and complete documentation, and having reliable legal counsel.

Do Not Wait Until You Are Summoned Before Looking for a Lawyer

If you are a business owner, executive, employer, or HR professional managing employees within your organization:

Do not wait for problems to arise.
Do not wait for complaints to be filed.
Do not wait until the labor office summons you.

Because by that point, you may already be at a disadvantage.

The best approach is to have a labor law attorney or labor law advisor from the very beginning. If you are currently facing labor law issues or want to establish a proper system from the start, you may consult Lawyer Arm Supasit today. Click >> Contact Us <<
