Confidential information (which includes things like client/customer/supplier lists, sales/pricing information, certain business methodologies, financial information etc) is often a business’ biggest asset.
Litigation (which is reactive) is rarely an ideal solution to protecting confidential information from misuse by former employees. Proactivity and pre-emptive action will usually be a better solution.
Pre-emptive action toward protecting confidential information involves ensuring that properly prepared employment contracts (with clauses legally reviewed regularly to ensure maximum protection and effect) as well as relevant policies exist (and that the day-to day practices of your business align with policy expectations). It also involves your IT systems and processes being able to trace the dissemination of information and to monitor things like printing and external device and cloud activity.
Are you adequately proactively protecting your business’ confidential information?
