Just throw it in an old tin and keep it in your pocket if you'd rather pack at work - you don't need to pay for a pouch unless you feel like you need one...
If you have a tobacco sold by the pouch then that also solves your problem right off the bat.
ie. Prince Albert, Carter Hall, Sir Walter Raleigh, Sail, et cetera
These are decent work smokes because they generally burn quickly and they aren't overly high in nicotine.
