A tech giant that has become the go-to place for tech workers with the promise of more paid vacation will allow workers to use smartphones to take advantage of the company’s expanded technology infrastructure.

Mark Zuckerberg, chief executive of Facebook Inc., announced Friday the new policy, which could come into effect starting in 2018.

The company said it was not disclosing the specific locations of its new paid-time-off programs.

The policy will allow employees to use their smartphones to access Facebook services such as Messenger and Pages, the company said.

Facebook said the policy would be available in the U.S. and Canada beginning this year. 

The decision comes after years of criticism from employees and employees’ unions that it was creating a culture that fosters unnecessary stress and has eroded the company and employees trust.

The new policy is part of a broader shift by Facebook and other tech giants to allow more flexible work schedules that encourage employees to get out of their comfort zones and work from home or on-site.

It is also designed to provide an environment where workers can concentrate on the things that matter most, such as creating and updating products and services.

The company has been pushing for a policy that would give workers more flexibility in scheduling and working from home, and for employees to be able to use mobile devices as a form of work.

Zuckerberg said in a statement Friday that he “believes that working from a smartphone is a great way to connect with our fans, learn more about the work we do and get more done.”

Facebook’s move comes as Facebook has been losing users, especially women, as it attempts to gain a foothold in the digital economy.

Facebook’s shares closed Friday at $19.75.

The social network is the subject of a class-action lawsuit filed in January alleging that the company failed to provide equal pay and overtime protections.

Facebook shares fell 6.6% in after-hours trading Friday.
