Retraining also include learning a new skill. He can retrain to be a fork lift driver or container driver, I heard they are well paid. Plumber or electrician can make abt 3k/mth too.the plumber who replace my heater can make about $80 per job and his schedule is always pack. 2 jobs a day for 26 days is a cool $2080 and I am sure he takes more job then that. Retraining also open up your option and opportunities.
