South Korea’s T’way Air adopts flexible four-day work model for staff

T’way Air will introduce a partial four-day workweek system from June, becoming the first airline in South Korea to adopt such a model for employees, according to reporting by ChosunBiz.

The South Korean low-cost carrier said it will implement a new “rest day” system designed to provide employees with greater workplace flexibility while maintaining overall working hours.

Under the new arrangement, eligible employees will work flexible additional hours during the week in exchange for an extra day off each month.

New work structure begins in June

According to T’way Air, employees will work an additional hour on Tuesdays and Wednesdays each week, while the second Friday of every month will automatically become a designated day off.

The airline said total working hours under the system would remain unchanged.

Key elements of the new policy include:

• One additional working hour on Tuesdays and Wednesdays
• The second Friday of each month designated as a rest day
• No reduction in total monthly working hours
• Flexible scheduling linked to public holidays where possible

The company added that the system would initially exclude employees performing essential operational functions.

Staff involved in:

• Flight safety operations
• Customer service activities
• Other critical operational duties

will not immediately participate in the revised schedule.

T’way Air said it plans to gradually expand participation by reviewing operational requirements, leave arrangements and working-hour structures.

Move follows integration with Sono Trinity Group

The airline adopted the work model after joining Sono Trinity Group, which has operated the same system across its affiliates since March 2024.

According to company statements cited by ChosunBiz, the group-wide policy was designed to improve workplace efficiency and employee engagement through more flexible scheduling practices.

A T’way Air official said the airline expects the initiative to improve employee immersion and operational efficiency while creating a more adaptable working environment.

The official also said the company intends to operate the system flexibly during months containing public holidays or extended breaks so that employees can connect their designated rest day with existing holiday periods.

The airline expects the arrangement to contribute to higher employee satisfaction levels.

Airlines face broader workforce and productivity challenges

The decision comes as airlines globally continue reassessing workplace policies following several years of operational disruption, labour shortages and changing employee expectations.

While remote work remains limited across aviation because of operational and safety requirements, airlines have increasingly explored flexible scheduling models for administrative and non-operational staff.

T’way Air’s move is particularly notable because airlines traditionally maintain rigid staffing structures due to complex scheduling requirements and regulatory obligations.

The company’s decision also reflects a wider trend among South Korean businesses experimenting with alternative working arrangements amid evolving labour market conditions and increased focus on work-life balance.

Operational constraints remain a key consideration

Despite the introduction of the new system, T’way Air acknowledged that aviation operations require continuous staffing coverage across safety-critical areas.

As a result, the airline is initially limiting the policy to employees whose schedules can support greater flexibility without affecting operational reliability.

Industry observers will likely monitor whether the initiative influences recruitment, employee retention and workplace productivity within the carrier.

The policy may also draw attention from other airlines evaluating alternative work structures as competition for skilled labour intensifies across the aviation sector.

For now, T’way Air’s phased approach highlights how airlines are attempting to balance operational demands with changing workforce expectations in one of the industry’s most labour-intensive environments.
