-There seems to be zero advancement opportunities for credentialing specialists.
-The managers pass on their responsibilities to the credentialing specialists and like to name people as "site lead" that comes with no bonus, no salary increase, and no added authority but they want you to pester your peers about getting their timesheets in on time.
