Job outlook
The BLS projects employment will decline by 4.3% from 2024 to 2034 — a loss of about 2,600 jobs. However, about 5,400 openings occur each year due to workers retiring or leaving the occupation. Automation and process improvements are reducing the need for manual operators in many facilities, particularly in food and chemical manufacturing.
Job seekers should focus on industries that are less prone to automation, such as pharmaceutical or specialty chemical production, where quality oversight remains hands-on. Geographic mobility to higher-paying states like Wyoming can also improve prospects.
