Contraft Inc. (Location: Chiyoda-ku, Tokyo / Representative Director: Kosuke Segai / hereinafter referred to as Contraft) and the General Incorporated Association National Construction Human Resources Association (Location: Chiyoda-ku, Tokyo / Chairman: Minoru Okano / hereinafter referred to as Zenken), which contributes to the development and advancement of the construction industry nationwide and is one of Japan's few specialized recruitment agencies for skilled laborers (craftsmen), have established a multifaceted support system in collaboration with Mitsui Sumitomo Insurance Co., Ltd. (Location: Chiyoda-ku, Tokyo / Representative Director President: Shinichiro Funabiki / hereinafter referred to as Mitsui Sumitomo Insurance) to address the pressing issue of "labor shortage" in the construction industry.
■ Background and Objectives
Currently, the construction industry is facing a severe labor shortage due to a large number of retirements due to aging and a lack of young entrants. Securing and retaining personnel, especially for subcontractors that support site operations, is a critical issue for the maintenance of the entire industry.
This initiative began with requests from specialized construction companies in the construction industry, who are clients of Mitsui Sumitomo Insurance, to "support the recruitment and retention of subcontractors." These requests led to consultations with Zenken, which has strengths in human resource support for the construction industry.
With the common goal of "solving challenges in construction sites," we will build a strong cooperative system at the operational level and provide site-led solutions.
■ Main Contents of Joint Support
We will back up companies' organizational strengthening through the dual pillars of recruitment (Zenken/Contraft) and retention/education (Mitsui Sumitomo Insurance).
＜Zenken/Contraft＞ 【"Offensive" Recruitment Support】
Analysis of the latest recruitment market trends, planning of effective job posting methods, and presentation of solutions for sustainable talent acquisition.
＜Mitsui Sumitomo Insurance＞ 【"Defensive" Retention Support】
Provision of information useful for corporate management, support for establishing a work environment that is easier for employees, and review of welfare programs (for engagement improvement).
■ Future Outlook
Zenken/Contraft, in collaboration with Mitsui Sumitomo Insurance, aims to contribute to the sustainable development of the construction industry by leveraging each other's strengths. In the future, in addition to nationwide expansion of joint seminars, we will also consider expanding consulting support tailored to the individual challenges of each company.
