Job hunting also should go beyond the passive looking at online job ads.
Network like crazy. Spread news of his job search on Facebook, Twitter, wherever. Tell everyone you know -- your hair stylist, your mail carrier, neighbors, etc. -- about his search. You never know who might have a job lead. If he's not on LinkedIn, open an account. Have him search for groups there for carpenters.
Attend meetings for professional groups for carpenters or the construction industry. This is a super way to meet others in the business and learn of job opportunities. Also look for local job hunting support groups. Another way to expand his network of contacts. People there are in active job hunting mode and may learn of openings just right for him.
Best of luck!
