Harvard’s imposition of a hiring freeze on Monday morning interrupted faculty hiring processes across the University, leaving professors scrambling to figure out how to fill vacancies — and how to keep their departments’ work running if they can’t.

Harvard University is the latest school to implement a hiring freeze as federal funding remains uncertain. President Trump has threatened to cut federal funding for schools that allow "illegal" protests. Universities use millions of dollars in federal funding for student aid and research programs.

The hiring pause at one of the nation’s wealthiest schools comes after other schools have also announced efforts to save money.
