You win, I am an a$$hole, yes is the appropriate answer. Here is a little document from the Bureau of Labor Statistics that was drafted to discuss the Job Openings and Labor Turnover Survey (JOLTS). It gives the definition of involuntary separation on page 2 right column, starting in paragraph 2.
http://www.bls.gov/osmr/pdf/st000160.pdf It specifically states in the beginning that "All opinions...Blah, Blah, Blah", but if the definition is being used for research at BLS I would guess its good enough for you to use. If you want the answer, just call the place you are submitting the app. Sometimes you run into the different institutions different policies issue.
Separations
There are three types of separations, as follows:
Quits, or "voluntary separations:" Employees who left
voluntarily (except for retirements or transfers, which
should be reported with “other separations”).
Layoffs and discharges, or
"involuntary separations:"
Separations initiated by the employer, including layoffs
with no intent to rehire, discharges because positions
were eliminated, discharges resulting from mergers,
downsizing, or plant closings, firings or other
discharges for cause, termination of seasonal employees
(regardless of whether they are expected to return next
season), and layoffs lasting or expected to last more
than seven days.
Other separations: Separations not included above, such
as retirements, transfers to other locations, deaths, or
separations due to employee disability.
