Sigma Joins Yurtec Corporation in Observing Corporate Ethics Month 2025: Spreading the Values of “Doing the Right Thing” and Building a Culture of “Speaking Up”

According to the message from Mr. Kobayashi Ikumi – Chairman of the Corporate Ethics Committee, Yurtec Corporation, fiscal year 2025 represents a significant step forward in promoting the culture of “Doing the Right Thing” and “Acting with Pride,” alongside fostering a workplace where everyone “Speaks Up” — a space where every voice is heard, respected, and constructively responded to.

In response to the initiative launched by Yurtec Corporation, Sigma – a member company of the Group – has actively participated in a series of discussions and awareness activities focusing on two key themes: “Using Inappropriate or Offensive Language” and “Doing the Right Thing Every Day.” This serves as a time for all Sigma employees to strengthen the core ethical values of the company, contributing to a professional, transparent, and humane working environment.

In his opening remarks, Mr. Kobayashi Ikumi emphasized the importance of maintaining professional ethics and mutual respect among colleagues. He reaffirmed that every member of the Yurtec Corporation, regardless of position or nationality, bears the responsibility to uphold the image of Yurtec and its subsidiaries, such as Sigma, through integrity and proper conduct.

At Sigma, topics related to the prevention of verbal harassment and the practice of proper communication are widely shared with all employees. Internal discussions are organized to help everyone better understand the line between constructive feedback and offensive remarks, while encouraging everyone to think carefully before speaking.

“Verbal harassment” refers to the use of words, gestures, or expressions that are derogatory, insulting, threatening, or emotionally harmful — actions that can damage another person’s dignity and confidence. At Sigma, all forms of disrespectful or hurtful communication are strictly prohibited.

Through communication campaigns and sharing activities, Sigma calls on all employees to show respect in every word, fostering a positive and safe communication environment — one where everyone is heard, understood, and treated fairly. The slogan “Think carefully before you speak” serves as a simple yet profound reminder of ethics in everyday speech and behavior...

Acting with Pride – Doing the Right Thing Every Day

In a time when public trust is a key measure of corporate credibility, Yurtec Corporation emphasizes that even a single ethical lapse can severely damage the reputation built over many years. Therefore, every individual must act within social and professional standards, consistently upholding the spirit of “Doing the Right Thing” and “Acting with Pride” in every decision and action.

For Sigma, this means that every engineer, office staff, and on-site worker must take ethics as their guiding principle. Every action and decision should stem from a sense of responsibility and professional integrity – two core values that define Sigma’s identity throughout its growth and development.

Building a “Speak Up” Culture – Creating a Trustworthy Workplace

One of the highlights of this year’s message is the emphasis on establishing a “Speak Up” culture. Mr. Kobayashi encouraged all Yurtec employees to exchange opinions openly, communicate honestly, and avoid assumptions such as “They probably already know” or “This isn’t worth reporting.”

Sigma embraces this spirit by promoting “active listening” – not only expressing opinions but also understanding and respecting others’ perspectives. This is key to cultivating psychological safety, ensuring that every employee feels heard, respected, and protected when raising their voice.

Whenever inappropriate behaviors or signs of misconduct are observed, Sigma encourages employees to report them to supervisors or through official consultation channels. This transparency and integrity continue to serve as the foundation for Sigma’s healthy, fair, and humane work environment.

Fostering a Workplace of Integrity, Transparency, and Responsibility

Corporate ethics are not slogans, but actions demonstrated in everyday work. Sigma remains committed to upholding honesty in business, ensuring that all operations and information are transparent and compliant. At the same time, the company maintains its social responsibility — not only to customers and partners but also to the community, the environment, and every employee.

Corporate Ethics Month 2025 is another opportunity for Sigma to reaffirm its faith in the power of integrity. Only when each individual acts with the right mindset and a sense of pride can Sigma collectively move forward, maintaining its reputation as a company strong in expertise and rich in human values.

From Awareness to Action

From Mr. Kobayashi Ikumi’s message to Sigma’s concrete initiatives, a shared spirit is clear: corporate ethics should not only exist in policy but must be embodied through heart, action, and example every day.

This October, during Corporate Ethics Month 2025, Sigma proudly joins the entire Yurtec Corporation in spreading these positive values — nurturing a workplace that values honesty, respect, and humanity, where everyone is heard and empowered to act, and where every action begins with doing the right thing.
