"Preventable Resignations" to Zero. Solving "Neglected Resignation Premonitions" Faced by 60% of SME Managers, HR Support "HR Department Pack" Renews with "Mikiwame AI" Integration for Data x Organizational Improvement Accompaniment

Jinjib (Osaka), which supports high school graduate recruitment and retention for small and medium-sized enterprises (SMEs), has significantly renewed its HR support service "HR Department Pack" as a resignation premonition and organizational improvement accompaniment model.

We have begun a partnership with "Mikiwame AI," provided by Leading Mark Co., Ltd. (Minato-ku, Tokyo; hereinafter "Leading Mark"), to support human capital management that solves issues between companies and "employees' true feelings" by combining data-driven "resignation premonition" with professional "organizational improvement execution accompaniment."

<Background of "HR Department Pack" Renewal> One day, an employee suddenly announces their resignation—but in many cases, that decision is not sudden.

As labor shortage bankruptcies in 2025 are projected to reach a record high (※1), "employee turnover" is a serious management challenge for companies, incurring a loss of approximately 5.8 million yen per person (※2). Especially for SMEs, continuing to hire without improving fundamental company issues only leads to a wasteful increase in recruitment and training costs.

※2 The loss when a new employee resigns within one year is approximately 5.8 million yen. Recruitment and training costs account for 39% of the total loss, a significant weight compared to 14% for employees in their fifth year. A mechanism is needed to timely grasp potential "resignation premonitions" and implement organizational improvements on an "execution basis."

Behind this renewal lies a "fatal gap" that management must confront.

In an internal survey (※3), 63.9% of former young ace employees (aged 20-35, who left SMEs in the past) (※4) responded that they "expressed their true feelings," and 94% responded that they "would have stayed if the company had responded."

On the other hand, 57.3% of SME managers and executives responded that they "noticed signs of resignation but were unable to take concrete measures or make improvements."

※3 94% responded with content indicating they "would have stayed if the company had responded." ※3 57.3% of managers responded that they "noticed signs of resignation but were unable to take concrete measures or make improvements."

This revealed the reality that in many companies, the "true feelings" of ace employees were conveyed, but the organization lacked the means to respond, leading to their departure.

While some ace employees expressed their true feelings, conversely, 36% resigned without confiding their true feelings. It is said that there is a "period of unease" lasting several months before an employee decides to resign, but many companies either overlook these signs or, even if they grasp them, lack solutions for "what to do."

※3 Ace employees spent an average of over 70 days worrying alone and solidifying their decision (period of unease).

This time, the "HR Department Pack" will be renewed into a model that supports the creation of an organization where people do not leave, focusing on "premonition detection" before receiving the belated notification of "desire to resign" and "execution of HR improvements" for retention.

By combining "Mikiwame AI" (personality diagnostic data, engagement surveys, and AI analysis for turnover premonition detection) provided by Leading Mark, with our organizational improvement accompaniment support, education, and training programs, we will offer SMEs a new form of human capital management: "grasping signs with data and changing the organization through execution."

<Features of the New HR Department Pack> Strength ①: Premonition Management (Mikiwame AI Integration) By introducing "Mikiwame AI" and conducting regular personality diagnostics and surveys, we visualize the condition of each employee and detect signs of turnover early.

<Comments on the Renewal> Takashi Mori, Senior Managing Director, Jinjib Co., Ltd.: Amid a severe labor shortage, bringing preventable resignations to zero is a top priority for SMEs. I am deeply grateful that we have been able to achieve the renewal of the HR Department Pack with the introduction of Mikiwame AI through a strong partnership with Leading Mark. By combining precise data analysis by AI with our strength in on-site accompaniment support, we will resolve the "gap in true feelings" between the organization and its employees, strongly promoting human capital management. We will work together with Leading Mark to not only prevent turnover but also to foster organizations where people shine and companies can grow sustainably.

Yuji Iida, President & CEO, Leading Mark Co., Ltd.: I am truly delighted to have formed a partnership with Jinjib. Through our daily interactions with customers, we have learned that "measuring alone does not change people." That is why "Mikiwame AI" has evolved into a product that not only visualizes the personality traits and conditions of each employee but also provides concrete action guidelines guided by AI. However, data is merely a compass; it is the power of people working on-site that truly changes an organization. By combining Jinjib's deep understanding of the SME現場 and their accompaniment capabilities with Mikiwame AI's expertise, we believe we can aim to bring "preventable resignations" to zero. We will contribute to realizing organizations where each employee's talent blossoms, where people not only don't leave but also shine, together with Jinjib.
