Amid its annual shunto spring wage negotiations, major courier firm Yamato Transport Co. said Wednesday it may seek to implement measures to ease burdens placed on delivery drivers to improve working conditions.

Under consideration is a plan that would eliminate one of the time slots in which parcels are delivered. Currently, there are six such periods: before noon, noon to 2 p.m., 2 p.m. to 4 p.m., 4 p.m. to 6 p.m., 6 p.m. to 8 p.m. and 8 p.m. to 9 p.m.

Reports say the firm may drop the noon to 2 p.m. option to allow drivers to take lunch breaks.
