Pay & employment outlook
Salary estimates for maintenance workers, machinery
The median divides workers into two equally sized groups by pay. It is not a starting salary, a school’s graduate outcome or a promise of employment. Lower percentiles are not automatically new graduates.
National outlook: 2025–2035
- Typical education for entry
- High school diploma or equivalent
- Related work experience
- None
- Typical on-the-job training
- Long-term on-the-job training
BLS national employment projections, 2025–2035. Openings include people leaving occupations or the labor force; these are not advertised vacancies. Education categories describe typical entry, not legal eligibility or a guarantee that any specific program is sufficient.
