Shrinkage

Shrinkage is a workforce management term that refers to any paid time an agent is not actively available to handle customer interactions. Shrinkage includes breaks, lunch, training, team meetings, coaching sessions, sick time, and administrative tasks.

Calculating Shrinkage

Shrinkage % = (Total shrinkage time / Total scheduled time) × 100

If an agent is scheduled 8 hours, takes a 15-min break, 30-min lunch, and 1 hour of training, shrinkage is 1.75 hours = 21.9% shrinkage.

Typical Shrinkage Rates

• Inbound contact centers: 20-30% (includes breaks, lunch, training).
• Outbound centers: 15-20% (less training; more call prep).
• Remote teams: 15-25% (varies; less office time, more breaks).

Impact on Staffing

If a customer service team needs 100 agents available to meet demand but shrinkage is 25%, they must hire 100 / 0.75 = 133 agents to ensure 100 are always available. This is why shrinkage is critical to staffing models.

Controlling Shrinkage

• Minimize training: Deploy pre-trained agents or use AI to reduce ongoing training needs.
• Optimize breaks: Stagger breaks to maintain coverage; don't let all agents break at once.
• Reduce meetings: Move non-urgent meetings to off-peak hours or asynchronous channels.
• Monitor adherence: Track unplanned absences and address root causes.

How AI Voice Agents Reduce Shrinkage Impact

AI agents work 24/7 with zero shrinkage. When AI handles 50% of inbound calls, the required human headcount drops, and shrinkage's impact on cost is reduced proportionally.
