Apply to any job you are interested in, and that you qualify for, don't let the misdemeanor stop you. The key is to be upfront and open about it, don't scream out the fact, but do tell them if it comes up. Misdemeanors are not asked about on most applications, and unless the job you are going for requires a background check, will not be an issue. Sure, you might be disappointed at times, it may come up and even after being honest and explaining, they may not want to take a chance on you; but, by limiting yourself upfront on what jobs you apply for, you might give up on a few you wanted which you could get. Hope it goes well!:-).
A misdemeanor theft is not that bad. Some companies will throw out applications based on any convictions and that's just something you'll have to deal with for now, but it shouldn't stop you from applying to whatever jobs you are qualified for. Remember to be honest when filling out job applications. George Zimmer of the Men's Wearhouse has gone on record saying he doesn't do background checks on applicants because he wants to give them a second chance. (I know he got fired, but his name has been in the news and comes to mind.)
Depending on what state you're in, you might be able to motion/petition to have the conviction expunged from your record down the road.
there are so many jobs that don't involve handling money,therefore the trust part is less important. but to tell you the truth;a theft misdemeanor is amost a non-issue.especially if it's a few years old. if I were in your place i'd apply for any job I liked. when you get to the part on the application that asks about your record be truthful. in fact go into some detail,enough that they can see you are no longer that person. if the conversation allows,in the face to face,speak openly and honestly about it,but make the impression clear, that was a one time foolish thing.
