1. Attendance Issues (No‑Shows, Tardiness, Job Abandonment)
This is by far the #1 cause of termination in U.S. manufacturing.
Plants report:
Repeated tardiness
Unexcused absences
No‑call/no‑show
Abandoning the job after breaks or shifts
Attendance problems account for 30–50% of all terminations in some facilities.
2. Violating Safety Policies
Manufacturing plants operate under strict OSHA and internal safety rules.
Workers are terminated for:
Ignoring PPE requirements
Unsafe machine operation
Bypassing lockout/tagout
Horseplay or reckless behavior
Because safety incidents can shut down production, zero‑tolerance enforcement is common.
3. Poor Job Performance
This includes:
Inability to meet production quotas
Low-quality output
Repeated errors
Failure to follow work instructions
Performance‑based terminations are rising as automation increases production precision.
4. Misconduct or Behavioral Issues
Common examples:
Disrespect toward supervisors
Harassment or hostile behavior
Fighting or threats
Insubordination
Manufacturing environments rely heavily on teamwork and shift coordination, so behavioral issues escalate quickly.
5. Failing Drug or Alcohol Tests
Many plants require:
Pre‑employment drug tests
Random drug screenings
Post‑incident testing
Failing any of these typically results in immediate termination.
6. Not Following Company Policies
This includes:
Unauthorized phone use on the floor
Leaving workstations without permission
Violating break rules
Unauthorized overtime refusal
Policy violations are especially common among new hires.
7. Inability to Adapt to Training or New Technology
As automation expands, some workers struggle with:
Learning new systems
Operating digital interfaces
Following updated procedures
This is a fast‑growing reason for termination from 2024–2026.
8. Dishonesty or Falsifying Records
Examples:
Falsifying timecards
Misreporting production numbers
Lying during investigations
Manufacturing companies treat documentation integrity as critical.
9. Theft or Misuse of Company Property
This includes:
Stealing tools or materials
Misusing equipment
Unauthorized removal of inventory
Although less common, these cases lead to immediate termination.
10. Failing Probationary Period (First 30–90 Days)
Many workers are terminated during the probation period for:
Low performance
Attendance issues
Poor cultural fit
Inability to meet pace expectations
This is especially common in high‑turnover plants.
