Do You Think Fed Gov't Positions Will Be Refilled?

I've read a lot about the many federal employees whom the Trump administration is firing or otherwise attempting to push out of their positions, but nothing about the positions themselves being terminated. (If I'm wrong about that, please let me know!) Assuming there's a large number of positions opened up in the wake of being vacated, do you think they will be refilled, or is the plan to leave them empty?
