"Under President Trump's budget proposal, federal employees at many agencies may need to acquaint themselves with a lately dormant but still much-feared term: Reduction in Force. If Trump's budget is enacted into law, it would hike defense spending by $54 billion - and pay for it with an equal cut in domestic spending at other federal agencies. Trump has said that reducing the size of the federal workforce -- better known by its acronym, RIF - is a top priority. It may not be as easy as Trump would like. Laying off federal workers requires going through a formal process that can be lengthy, expensive and disruptive to the workplace, experts say. And various legal and union rights may come into play, as they do for the similarly complex process of firing a federal worker for misconduct."
