Advertising giant Dentsu Inc. intends to scrap its usual business day on Nov. 17 and hold a company-wide session in Tokyo attended by about 7,000 employees to discuss and review working methods.

Employees have been asked only to carry out urgent tasks on the date, which is a Friday, and business partners have been requested to refrain from visiting the firm's headquarters in the Shiodome district in Tokyo’s Minato Ward where the meeting will be held.

Employees outside of Tokyo will be asked to attend the meeting online.

The advertising giant was fined 500,000 yen ($4,400) on Oct. 6 for violating the Labor Standards Law in failing to prevent excessive overtime by its employees, including female rookie Matsuri Takahashi, 24, who committed suicide.

Dentsu made a plan in July to improve its working environment and arranged for Nov. 17 to be a day when employees could participate in a review of procedures.

During the meeting, outside lecturers will discuss the correct way to approach their jobs, and reports will be heard on any improvements of the working environment since July's plan was put into action.

The company intends to continue to hold similar meetings in November every year, according to a source.
