Seems like every poster to this thread has had issues good and bad with various individuals. I believe the single most important point is that the person has to have the skills and ability to perform the job you want done. If you are into chemicals and hazardous waste, surely you can't have a person who can't read or is dyslectic perform the work. There are other types of work you learn on the job and become skilled. If the person does not have to meet the public, long hair, tats or attire don't have much to do with what the person can produce.
Take a moment to evaluate what you would in this situation. Man comes in to fill out an application for a heavy equipment mechanic position. He's clean cut, has on normal work clothes and boots. He starts to fill out the application and soon asks the secretary for a continuation sheet to list work history. After an hour plus he is still filling out the application and is on his fourth continuation sheet. I step out and ask to see what he is noting on the continuation sheet. I look them over and ask him just to list the types of work he has performed and start off with your education and technical schools attended.
Here's what he listed;
Dropped out of school 11th grade
Attended trade school for electronics and electrical systems
Class on hazardous waste handling
Class on hydraulic systems
Type of work performed
Lathe, mill and welding in fab shop
Aircraft sheet metal mechanic
Public works, sewer system, lift pumps and garage
Final and flight operations on aircraft (avionics & flight controls)
Mechanic, heavy equipment
Licensed as a General Contractor
Licensed as Environmental Assessor
Senior Construction Project Manager
Proficient in AutoCAD (mechanical, civil, architectural)
Plant Engineer
College instructor (Civil Engineering)
Farming (35 acres)
After a quick review, I asked if he had graduated from a college or university. He said "no, I read a lot, test well and I am very good with computers".
Here's the situation, he's 70 yrs old, said he has no ailments and rarely has to see a doctor. Would you hire him as a heavy equipment mechanic?
