The bill, which aims to reduce the working week from 45 to 40 hours within five years, has stalled in Congress since it was introduced in 2017 by then-lawmaker and current government spokesperson Camila Vallejo.
Boric has given "urgency" to the bill, a provision in Chile's constitution that forces lawmakers to consider a bill when mandated by the president.
Lawmakers will debate a series of changes to the bill made by Boric's government, including a revision extending the reduction in working hours to workers in special categories, such as public transport drivers and domestic workers.
"These improvements are essential to bringing us closer to a new Chile, one that is fairer," Boric said during a ceremony Tuesday at the presidential palace.
The center-left government has promoted dialogue with unions and worker federations along with representatives from small, medium and large companies at a time when the economy of the world's largest copper producer is slowing down and faces strong inflationary pressures after a rapid post-pandemic recovery.
Boric said his government expected the bill to be voted on and approved as soon as possible by both legislative houses.
