Giving kids a chance is good, but adults should know better and do better. I've held positions of trust including a stint as a bank courier, and there is no slack given- either you are completely trustworthy about theft or you're not. Yes it's harsh but that is the reality of the world. I was once fired from a job for stealing (which I didn't do- it was employee jealousy and they set me up when I wasn't there- I was later vindicated when they turned out to be a thief themself and got caught) and in my early days as a car mechanic I had all my tools stolen which almost cost me that job. There can be consequences far beyond what things may seem on the surface but the bottom line is:
any and all theft is wrong.
