Union or non-union: which is better?
Union apprenticeships generally pay more during training and offer stronger benefits and pensions, but can have waitlists. Non-union paths through contractor associations or direct hire can start faster. Many successful tradespeople do both over a career.
Will AI replace trade jobs?
Physical trades that work in unpredictable real-world environments (wiring buildings, fixing pipes, driving trucks) are among the hardest jobs to automate. The BLS projects continued openings driven mostly by retirements.
