Promoting diverse and flexible work styles

Basic approach

Idemitsu Kosan has created an environment where a diverse range of employees can work comfortably, and has also established telework systems, flextime work systems, and satellite offices, all of which help ease the burden of commuting. The expansion of working hours flexibility, which began in fiscal 2020 as an emergency response to the coronavirus pandemic, has been institutionalized since fiscal 2021, creating a more flexible working environment. In order to continue promoting new ways of working using DX, we have established guidelines for online (communication, meetings) and created a system that allows employees to work flexibly.

●Systems related to working styles

Flextime working system Flexible time Can be
(Head office etc. 7:00-22:00)
Core time None
Interruption of work Possible
Telework system
(Some occupations are not applicable)
Work place Ability to work from home, satellite office, or mobile
Number of meetings Without limit
Used in conjunction with going to work Possible
Interruption of work Possible

Initiatives

Initiatives to promote paid leave taking and reduce working hours

Working hours management is a system that accurately grasps the actual working conditions of employees (including managers) through a work management system, and aims to improve productivity by continuously raising awareness of working hours. With a focus on improving the workplace culture and engagement, we are working to improve work efficiency and productivity, while also aiming to improve QOL (Quality of Life).

Main initiatives to encourage taking annual paid leave

・Promoting leave taking for human resources executives
・Disclosure of acquisition rate by department
・Encourage students to take 5 days in a row during summer vacation, etc.

Manufacturing & Technology Department Initiatives

Manufacturing & Technology Department Gate, with the aim of encouraging employees to work with a sense of "engagement" and to increase their competitiveness and engagement, the head office and manufacturing sites work together to promote diverse and flexible work styles from the perspectives of "work environment," "education and training," and "operational efficiency (promotion of DX)."

Working environment

At Refineries/Complexes, we aim to create an environment in which employees can autonomously choose the most productive working style that is best suited to their job, regardless of time or place - "anytime, anywhere, with anyone." We are renovating work spaces incorporating the concept of Activity Based Working (ABW) and promoting hybrid work that integrates operations, maintenance, and staff.

Education/development

For PEs (production engineers) in the operations department, we introduced the EX (expert) system in fiscal 2021, and established a new CDP (career development plan) and growth targets for each grade, as well as a training system that takes into account the diversity of career development. To date, 11 PEs have been certified as EXs, opening up new avenues for success. For MEs (maintenance engineers) in the maintenance department, we have established a "maintenance chief system" in fiscal 2023, which appoints maintenance engineers who will work at Refineries/Complexes as experts on equipment and models, in order to improve maintenance technical skills suited to the field, strengthen training, and increase motivation. Having cleared strict selection criteria, three maintenance chiefs are currently working.

Improving operational efficiency (promoting DX)

In 2022, we established a business structure reforms and DX Promotion Office at Chiba Complex to oversee and promote DX activities at Refineries/Complexes sites. We aim to improve operational efficiency through DX activities, ultimately developing strong human resources and creating workplaces where each site can utilize DX on its own. As one specific initiative, we have developed "SDM-kun" (Smart Digital Maintenance: maintenance work support system) Refineries/Complexes and deployed it to each site. This system aims to streamline the entire maintenance management process, from planning to execution to evaluation of inspections and construction work carried out at refineries and business sites, and improve equipment reliability. Additionally, by utilizing data integration technology that centralizes various types of data that were previously dispersed, we have achieved increased efficiency and improved quality in our investigation work. Going forward, we will continue to engage in further DX activities that contribute to safe and stable operation.
