Automotive service technician
A day looks like: Diagnosing and repairing vehicles; increasingly electronics and EV systems rather than wrenching.
What stops people: Dealerships prefer applicants who already have a shop class or co-op.
Downside: Many shops pay by the job, not the hour, so slow weeks hurt. You buy your own tools, often $10–20k over a career.
Industrial millwright
A day looks like: Installing, maintaining and repairing industrial machinery. Mechanical problem-solving with heavy equipment.
What stops people: Fewer openings than construction trades; factories and plants hire in small numbers.
Downside: Shift work in manufacturing plants. If the plant closes, you move.
