The Workplace Investigation Toolkit

A fair investigation is not about building a case. It is about establishing what happened, testing the evidence properly and showing how the conclusion was reached.

The Workplace Investigation Toolkit is a practical UK management resource for line managers, supervisors, team leaders and small-business owners who need to carry out internal workplace investigations fairly, consistently and with a clear audit trail.

It provides a disciplined process for planning the investigation, preserving evidence, conducting interviews, assessing conflicting accounts and writing balanced findings.

Inside the toolkit:

• The TRACE investigation framework

• Terms-of-reference guidance

• Investigation planning tools

• Evidence log and interview structure

• Neutral question prompts for complainants, respondents and witnesses

• Guidance on credibility, corroboration and conflicting evidence

• A practical report structure

• A fully worked management example

• A final fairness and quality checklist

The approach is evidence-led, measured and designed to help managers explain not just what they concluded, but how they reached that conclusion and what limitations remain.

Ideal for:

• Line managers

• Supervisors and team leaders

• New and developing managers

• Small-business owners managing employees

• Anyone asked to conduct an internal workplace investigation
