a son & his problem

I am not for sure but i do belive it will affect him the only reason it may not is because it was a pre-employment. But I do know that if he was already driving employers would be able to see it on the back ground check and when you fil out your app with them it will ask if you have failed any and they will find out if you are lying so it is better to let them know up front. However I do know a guy that worked for a smaller company and the owner worked with him while he got clean twice but finally the third time that was it. But I do know he drives for a company now as well. Also know another guy who was given a second chance and he got his act together. I guess it just depends on who you know. Just starting out though and not knowing anybody or having any work history may be a disadvantage. Maybe the best way to find out would be to just call a few companies and ask some questiions. Thats waht I do when I'm trying to find out some info go straight to the source. Good Luck.
