For years, Republicans in Congress have been eyeing an overhaul of the federal workforce — by reducing the number of workers and curtailing benefits and pay while making it easier to fire bad employees.

Now, with a president-elect who has promised to do much the same, 2017 could be the best time in recent memory to make sweeping changes affecting those who work for the bureaucracy.

One major plan is being readied by Rep. Jason Chaffetz, the chairman of the House Oversight and Government Reform Committee. The Utah Republican calls it “high on our agenda.” While details remain sketchy, it would likely mean big changes to the generous retirement benefits given federal workers, mainly by looking to shift new employees from a defined benefit into a market-based 401(k).

He is also interested in making it easier to fire workers who perform badly and wants to reduce the federal civilian workforce, which currently numbers 2.1 million employees, not including U.S. Postal Service employees.

“We’ve got to deal with budget realities, and while we have good federal workers, we have too many of them,” he told Roll Call.
