We absolutely need that money today, is there a law or anything of that sort that makes them obligated to do something to get him his money by the end of the day?

Have him call the Human Resources Department and see if they can issue a new check that can be mailed to your home, with luck the check will be found by the end of the day.
Good luck!

request them to print off a new one and have them void the lost check.

Sorry I was hungry.

what do you expect from that dump

Your husband needs to go to the store, file a canceled check and fax the headquarters the information. Home Depot Corporate will overnight a new check.

Your stores management can help with the process.

No, there is not a law stating that they must have it by the end of the day. Is he under a contract? check to see if it is in there, if so then maybe you have a case.
