Employment Law & HR Compliance
Workplace Investigations
Running a disciplinary or grievance investigation so its findings hold up later — before HR, at the Labour Court, or in front of the person you dismissed.

What we handle
Scope of work
Scoping the investigation — what exactly is being investigated, and against which rule
Choosing the investigator and keeping the decision-maker separate
Interview plans, questions and records that stand up on review
Evidence gathering within PDPA limits — devices, CCTV, email and messages
Suspension during the investigation, done on the right terms
A written report with findings, and the options each one leaves open
How it works
How we run the matter
- Assess the allegation and the rule it engages, and start the clock
- Agree the scope, the investigator and any suspension
- Secure the evidence before it can be altered
- Interview the witnesses, then the employee, on the record
- Deliver a written report with findings and options
- Support the decision that follows — warning, discipline or dismissal
Documents to prepare
- The complaint or report that started it
- The employee’s contract and the workplace rules in force
- Previous warnings and the personnel file
- The evidence gathered so far, and where it came from
- The date the company first learned of the allegation
