The direct answer (AEO)
Union field worker time tracking requires GPS systems negotiated through collective bargaining — emphasizing shift-only location (not 24/7), transparent data access rules, and immutable hour exports for prevailing wage and grievance proceedings. Employers who impose always-on tracking without CBA review face grievances and work stoppages.
Successful rollouts joint-committee GPS policy before technology selection.
CBA negotiation checklist
| Topic | Union concern | Employer need |
|---|---|---|
| When GPS active | Off-duty privacy | Shift boundaries |
| Who sees live map | Surveillance | Dispatch safety |
| Data retention | Discipline misuse | Audit period |
| Discipline triggers | Arbitrary GPS flags | Buddy punch stop |
| Personal device | BYOD compensation | Cost savings |
Shift-only model for union acceptance
GPS starts at Start Shift, ends at End Shift. No location storage off-duty. Route replay available for pay dispute — not continuous manager viewing without cause.
Prevailing wage and Davis-Bacon
Union construction on public works needs GPS hour evidence matching certified payroll classifications.
Grievance-ready exports
session_id, geofence_id, clock timestamps, approval chain — exportable for steward review without editing.
Implementation with union partners
1. Joint committee reviews vendor shortlist
2. Pilot one crew with union observer
3. 90-day CBA side letter if needed
4. Full rollout with shop steward training on dispute process

FAQ
Can unions block GPS tracking entirely?
They can bargain scope — shift-only with grievance procedure usually acceptable vs blanket ban.
Union GPS vs non-union field tracking?
Same technology; CBA adds process requirements and data access rules.
Does GPS replace union time stewards?
No — supplements sign-in sheets with objective timestamp evidence.
Personal phone GPS for union members?
CBA should address BYOD; employer-provided devices simplify consent.
