Seems like Wells Fargo wants to hire him or they wouldn't be asking for all this specific information. In any financial services occupation they want to know the specifics. Falsifying time cards is pretty benign compared to falsifying securities transaction paperwork. As for the bankrupsty - I don't think anyone really makes a big deal out of that these days. With the economy the way it's been lately there are a lot of people who have been over-extended.
I used to be a Director of Human Resources and handled lots of resumes and advised our executives on hiring decisions. This is what I would say regarding your husband if asked: Either the bankruptsy or the falsification of time cards on their own would not bother me. People get overextended on the kind of house they buy or vacations/cars they finance and they may financial mistakes. It happens and hopefully they learned this hard lesson. People also get into a situation where, due to outside circumstances they are frequently late - such as having to take a child to daycare each day when the wife picks up in the evening. But if there's lots of ongoing construction delays a mature person realizes that extra time should be factored in to the commute time - and should leave home earlier each day. The fact that time cards are falsified in itself isn't awful - but most employers would not get rid of a highly valued employee if it was only a time card issue. They may have used this as an excuse to get rid of this guy because he was underperforming or had other issues. So - taking into account both the bankruptsy and the falsified time cards it would appear that this is an person who doens't have a personal habit of discipline and self correction. Given the choice of two otherwise equal candidate I'd recommend the one who doesn't have these two issues if possible.
Now - please realize, I'm telling you what I would say, as an HR Director to a hiring manager. I don't know your husband and these conclusions could be completely wrong. He may also be a very charismatic people-person, who by nature is not real detailed oriented. It could also be that a manager at the former job told him that as long as he makes up his work he can file the time card showing on-time arrival and now that manager has left the company. Those things factor favorably, as does a solid explanation of the bankruptsy such as extraordinary medical bills, ovetended credit after cosigning a loan for a family member who deafulted, etc.
Basically, the more information provided the better his situation will be. We used to run credit checks on gasoline tanker truck drivers since a person in debt may sell a few thousand gallons of gas from his tanker to make some fast cash. But if he was able to explain why he got into debt and how he was working to get out of debt we'd hire him. But if he dodged the question or was kind of flakey we'd think the worst and assume he was a chronic gambler and would always need money ( or something else like that).
The more open and honest your hsuband is, the less he has to hide and the more candid he is, the better it is for him. The employer wants to see recognition that he made mistake, he learned from them - and they want to see what he's doing to change. If he handles it this way he will be a solid candidate for the job. Good luck mama!
