Specifically, however, you want frequencies >= value. Best to negate
your variable before calling -cumul-:
gen work = -employees
cumul work , gen(freq) freq equal
tabdisp employees, c(freq)
drop work
Note that what you want is more commonly called the reverse, converse
or complementary cumulative frequency. Calling it "inverse" runs a big
risk of confusion with the quantile function.
