Agencies should aim for a 30-day deadline to implement Trump’s return-to-office executive order, according to a memo from the Office of Personnel Management.

The State Department has already begun to implement the president’s memo cancelling telework agreements as of March 1 and remote work arrangements July 1, with exceptions for military spouses and employees with disabilities.

According to the memo, OPM is requiring all federal agencies to notify their employees by Friday at 5 p.m. of their compliance with the executive order. Agencies are also mandated to update their telework policies with new language emphasizing in-person attendance.
