The Client: Urban Apparel

"Urban Apparel" (name changed for confidentiality) is a mid-market fashion retailer with 8 locations across London, Manchester, and Birmingham. Despite a strong brand, their operations were bleeding cash due to people problems.

The Problems (Early 2023):

  • 78% Staff Turnover: Nearly their entire workforce left every year.
  • 6-Week Hiring Lag: Positions sat empty, directly losing sales on the floor.
  • Financial Drain: Spending £163,000/year on reactive recruitment agency fees.

The Sigma Turnaround Strategy

We didn't just "find staff." We rebuilt their entire people engine. Here is the 4-phase plan we executed over 14 weeks.

1

Diagnostic (Weeks 1-2)

We analyzed exit interviews and discovered pay wasn't the issue. The problems were cultural fit and lack of career progression.

2

Hiring System Overhaul (Weeks 3-6)

We shifted job profiles from "Experience Required" to "Attitude & Potential." We introduced a multi-stage rapid assessment:

  • Sigma Phone Screen: Culture fit check.
  • Paid Trial Shift: 4-hour paid trial to see real work behavior.
  • 10-Day Promise: Reduced time-to-offer from 42 days to 10 days.
3

Structured Onboarding (Weeks 7-10)

New hires previously left within 60 days. We built a 90-Day Journey including a "Welcome Pack," assigned buddy, and formal career check-ins at Month 2 and 3.

4

Management Training (Weeks 11-14)

We trained 8 Store Managers on behavioral interviewing and how to motivate Gen Z staff, moving them from "fire-fighters" to leaders.

Why It Worked: 5 Key Success Factors

1

Speed Wins Talent

Top retail candidates have multiple offers. Our 10-day process captured the best people before competitors could react.

2

Trial Shifts are Critical

Resumes lie; work ethic doesn't. Paid trial shifts identified poor fits immediately, saving bad hire costs.

3

Career Pathways

We introduced clear steps (Associate → Team Lead → Manager). Staff stayed because they saw a future.

"Before Sigma, we were in a constant hiring crisis. The transformation has been remarkable—not only are we saving £77k/year, but our stores are better run and customers notice the difference. The 45% revenue growth is the real proof."
