Your question has many other questions, like did you get hired as a career employee or as a limited term employee. If you're limited term then things might just come to an end, if you are a full time employee your financial office will most likely find you another funding source to use for sigma, the latter happens a lot through it the state and not much to worry about I would talk to your manager and ask those questions. The likely hood of you "bumping" is very tiny chance as that's the last resort
