Can employee at Walgreen's transfer to another store out of state?

Yes. A lateral transfer within the company is possible pending a few stipulations. There must first be a position open at the location you wish to transfer. Second, you must have manager approval (from your current manager and the new manager). And third, you must have district supervisor approval (from your current supervisor and the new supervisor). Pay scales frequently are different depending on the market, so inquire with your manager regarding this matter.
