A new memo from the human capital agency says federal agencies should change policies and require workers to be in the office full time by the end of the week.

Agencies should require workers to comply within roughly 30 days of the policy announcement, White House Office of Personnel Management says.

The White House told federal agencies to detail by Friday a list of federal employees who are on probationary status and make recommendations on whether they should remain on the job. President Donald Trump has vowed to reform the federal workforce and sharply reduce regulatory efforts.
