Red Deer RCMP say Alberta Blue Cross discovered fraudulent claims during an audit of employee coverage at a hog-slaughtering plant.
Police say more than 100 Olymel workers were encouraged to sign blank claim forms, which were submitted with false receipts.
Investigators allege the women received a significant percentage of each claim payout.
Examination of hundreds of files between January 2007 and January 2010 showed that most of the false claims were for massages.
Donna Nast, who is 41, and Noralyn Zadrozy, who is 42, each face charges of fraud over $5,000 and using a forged document.
They are to appear in Red Deer provincial court next month.
