Toward the Realization of Work-Life Balance

We are pursuing a number of measures to create a fulfilling workplace for each and every employee. Recently, we have been striving towards the realization of work-life balance through efforts to reduce working hours focusing on both tangible and intangible aspects such as increasing operational efficiency with use of smart devices.

Labor-Management Relations

Taisei Corporation has a union shop agreement with its employees union, and all 7,592 employees, except for management, belong to the union. The Company conducts various surveys and dialogs between labor and management every year for the purpose of facilitating labor- management relations and the business activities of the Company. Changes in working conditions are listed as items determined in advance through discussion between labor and management.

Health of Employees

In order to enable employees to manage their mental and physical health, we encourage workers who displayed symptoms in a health checkup to seek medical attention. We also ensure that overworked employees meet with a physician.
Furthermore, we encourage the taking of stress checks, carry out Line Care Training for management employees, and prepare a broad support system in collaboration with specialized organizations and industrial physicians.

Health Management Initiatives

Taisei Corporation was recognized under the 2017 Certified Health and Productivity Management Organization Recognition Program (White 500) established by the Ministry of Economy, Trade and Industry in FY2017.

Working style Reform through Use of ICT in Daily Operations

Social issues including risks to employee health due to long working hours have recently come to the fore. In order to resolve these issues, Taisei Corporation is promoting working style reform through ICT solutions such as utilization of the Field Pad app. In May 2016, we introduced the Office 365 cloud service, to create a business environment "that can be safely used by anyone, anytime, anywhere, with any device." We have promoted use and spread of the service, and results of an in-house survey showed that an average of eight hours could be saved per month. The Taisei Group will continue seeking to enhance its vibrant workplace environment with the aim of realizing work-life balance.

Improving Health and Safety Standards

Health and Safety Policy and OHSMS System

Based on the ideal of "Safety First," Taisei Corporation works hard to ensure safety in a tangible form day to day in concerted efforts among its employees, group companies and cooperating companies. We are committed to this under the "Health and Safety Policy," which the President indicates by systematizing and organizing the "Taisei Occupational Health and Safety Management System" (TAISEI OHSMS), to eliminate accidents and damage and prevent third-party accidents.
TAISEI OHSMS is established based on the safety and health management techniques and know-how which Taisei Corporation has accumulated over many years. Using this system as a platform, the PDCA (plan-do-check-act) cycle is properly implemented to improve health and safety standards.
In addition, we work to prevent accidents and damage by conducting risk assessment and taking necessary measures to reduce risk, based on the results of audits of the actions under the "Health and Safety Management Policy." We also carry out thorough construction site patrols and safety education for construction workers in order to ensure health and safety management based on TAISEI OHSMS.

Safety Education Support for Specialist Contractors (Cooperating Companies)

Taisei Corporation cooperates closely with the "Taisei Health, Safety, and Environment Cooperation Association," which consists of cooperating companies all over Japan, to prevent accidents and damage. Members of the Association work to prevent accidents and damage by participating in the "Safety Conference (January)" and the "Safety Promotion Conference (June)" held by Taisei Corporation each year, and by using educational and instructional material for health and safety management such as the journal "Cooperation" and the "Collection of Accident Cases."

Establishment of Various Foremen Systems

In the civil engineering field, the system for rewards for excellent civil engineering skilled workers, under which a reward is paid to the workers with excellent construction skills who contribute to construction work at the sites of Taisei Corporation, is introduced to improve the overall capabilities, including quality, safety and skills.
In the building construction field, a system for the highest quality foremen was newly established and has been put into operation upon partial revision of the first-class foremen system during FY2015 to further improve the foremen's construction management capability, including quality, skills and safety to strengthen the production system.

Improvement of the Health and Safety Standards

  • Safety Administration Department, Safety Administration Division

The Company set a target of "achievement of zero fatal accidents" in 2016, but regretfully one fatal accident occurred.
For 2017, we have again set a target of "zero fatal accidents," and will promote various measures aimed at "shifting from recurrence-prevention safety management to preventive safety management."

Number of Fatal Accidents ・・・1 cases

Health and Safety Initiatives at Construction Sites

We are pursuing worksite-led activities in order to improve health and safety levels at the "(Tentative Name) Jingumae Plan" construction site in Harajuku, Tokyo, where we are constructing a high-rise building with 23 floors above ground and 3 basement floors.

Promoting Activities Led by Foremen

Specialized contractors (cooperating companies) are involved in work on construction sites in a wide range of fields until the building is completed. An average of about 40 foremen, who are the leaders from each cooperating company, along with some 400 skilled construction workers, enter this construction site each day. In order to preserve safety at a worksite where different companies are involved depending on the stage of work, and new skilled construction workers join the site each day, it is vital that everyone share an awareness of safety and engage in efforts collectively. We have therefore organized a Foremen's Council that cross over company borders at this worksite, and formulated the council's slogan, "Dedicated Wholeheartedly to Progress." We are implementing initiatives under four sub-committees, namely environment, safety, vehicles, and publicity, in order to work as one to realize zero accidents and zero damage.

Emphasizing Unity while Maintaining Alertness

The Foremen's Council engages in various activities such as conducting safety patrols from various perspectives depending on the day of the week, promoting the "point-and-call" practice, which is an effective safety check, and practicing individual danger prediction activities at morning assemblies. In addition to constantly maintaining a sense of alertness on the site, we also create innovative ways to ensure that safety measures quickly become familiar without being simply rote, such as publishing the Jingumae Newspaper, a tabloid-type paper that enables all construction workers to share an understanding of the project status, and putting up manga-style posters. We further strengthen the sense of unity by creating plenty of opportunities for deeper, direct communication among construction workers, such as by holding occasional fireworks, sports festivals, barbecues, and cultural exchanges among construction workers of different nationalities.

Fostering a Culture of Preventing Accidents and Damages before They Happen

The repetition of these processes fostered a culture where workers can freely speak their minds to each other. This produced a virtuous circle, whereby a higher level of awareness among all employees is reflected in improvement activities, such as when active communication leads workers to caution each other and prevent trouble before it occurs. In addition, the openness of the workplace boosts the morale of construction workers and facilitates smooth coordination among cooperating companies, thus promoting work efficiency as well as safety.

Osamu Kubota, Construction Site Manager, (Tentative Name) Jingumae Plan Construction Site, Tokyo Branch

Skilled construction workers are the leading figures at a construction worksite. What the site manager says does not have any effect unless it penetrates to each and every person working on site. Through activities led by the foremen, we can surely achieve zero accidents and zero damage if everyone thinks of this place as "their site" and considers fellow workers as "their family." Creating that environment is an important job for the site manager.
