First Offense Shoplifter

My question involves a background check in the State of: Pennsylvania. I was arrested for shoplifting 1st offence in New Jersey in Aug of 2009. (just over $100)
I plead guilty. Paid fines & served community service. (idiot me figure I would own up to it & not get a pub. def.)
I am now married, live in PA, and have been hired by a retail craft store, but fear that when the background check is run they will dismiss me.
1st- Is this considered a misdemeanor or a felony?
2nd- Will this prevent me from getting jobs?
3rd If so how do I get a job now?
Thank You

If it's under $200 it's not a felony. If it's over it is. (Actually, New Jersey doesn't technically classify things as felonies or misdemeanors, but most states consider anything with a potential sentence of over a year to be one).
Who knows if it will stop you from getting a job, but lying about it and getting found out will almost certainly result in immediate firing.
Expungement is a possibility in NJ. It's involved, I'd recommend a lawyer.

I'm not 100% sure but I believe to have it expunged in NJ it is a 3yr wait. It's been a little over a year.
Yes I should've have a lawyer, but plead guilty & got it over with. That was my 2nd mistake. (1st being stealing to start with) I haven't lied on my app, I put I wasn't convicted of felony, but fear I wont be given a chance at my job once the background check is run. Thanks for your input.

Sometimes it depends on the employer & the job you applied for whether you get hired
with a history of stealing.
