I tnink it depends on the employer. I have read here on this board and other boards, that it considered legal, but someone's employer did had issues with the state that it was issued, in regards to the legality of online pharms(they were aware of online pharms)
If the script/bottle is current I would believe it would be considered legit, as long as your name/doctor's name/name of pharm on the bottle.

Good luck!
