Haven't seen anyone mention this yet: there is a difference between "listed employees" vs. "full time employees" (FTEs) vs. "full time employee equivalents" (FTEEs). In this very specific case, physicians/providers often work 0.125-0.875 (i.e. one hour to seven hours of an 8 hour day) for one entity (say, their primary teaching hospital), and the remainder for another entity (the university where they are also an listed as adjunct professor, etc.).
You could have 10,000 employees, however 4,000 of them are physicians/providers, 3,000 of whom work less than full time for that entity. So you are looking at 10,000 employees, but some number between 7,000 and 9,999 FTEEs. These are very different, and very relevant, numbers when looking at healthcare organizations.
"Methodology & Definitions
Staff Headcount
Staff headcounts include all regular, benefits-eligible university employees. With rare exceptions, employees must be appointed at 50% FTE (full-time equivalent) or more for at least six consecutive months in order to be eligible for benefits. The Professoriate and employees of SLAC are not included. Employees with multiple jobs are counted only in the job that is tied to their benefits, typically the one with the largest number of standard hours."
