Hello, thank you for the question.
Let's cut to the chase. Your sentencing looks good.
I recommend that you go to court and talk to duty counsel in advance of your court date, ask about what diversion programs might be available so that you can avoid a conviction altogether.
You won't be looking at jail time, especially if you make restitution beforehand. If you do pay them back, just don't admit that you are culpable of stealing, rather say something like "I'm sorry about what happened and I hope that by your acceptance of this sum back we can put this behind us" or something like that, which doesn't specifically admit guilt.
Now, I won't lie to you because that doesn't help you. This is more serious than a simple shoplifting charge. Employees who are convicted of stealing from employers tend to be dealt with more harshly because there's a contractual understanding of trust involved. However if you pay the money back soon that will help. And if this is your first offence then you aren't looking at jail time or anything serious.
Still, you want to avoid a criminal record if you can. So if you make the restitution soon voluntarily and make an apology without admitting the crime, you could well come out of this okay.
Does that help? Please reply if there's more to discuss. If not, then I'd appreciate a positive service rating please.
