When a senior employee leaves your business to join a competitor, it can create significant risks. From the loss of clients and key staff to the potential misuse of confidential information, the impact on your business may be substantial. As an employer, it’s important to have legal safeguards in place to protect your commercial interests and reduce the likelihood of disputes.
In this article, our employer lawyers explore what employers can do to safeguard their business when a senior employee moves to a competitor.
Key Takeaways
Restraint of trade clauses can restrict a departing employee from working for competitors or soliciting clients.
Confidentiality agreements protect sensitive business information, even after employment ends.
Well-drafted employment contracts are essential for enforceable protections.
Immediate action can be taken through injunctions if a breach occurs.
Practical steps such as exit interviews and restricting access to information reduce risks.

Protecting Your Business When a Senior Employee Joins a Competitor
1. Use Restraint of Trade Clauses
A restraint of trade clause in an employment contract can prevent a senior employee from:
Working for a competitor within a set timeframe and geographic area.
Soliciting or approaching your clients, customers, or suppliers.
Recruiting your existing staff.
While courts in Australia are cautious about enforcing restraints, they will uphold them if the restrictions are reasonable and necessary to protect legitimate business interests.

2. Enforce Confidentiality Obligations
Senior employees often have access to trade secrets, pricing strategies, and client information. A well-drafted confidentiality clause ensures that this information cannot be disclosed to competitors or used after they leave.
Unlike restraint clauses, confidentiality obligations generally survive termination of employment.
Choosing between different employment law firms Brisbane offers can feel overwhelming, but Prosper Law’s proven experience in workplace disputes will make the process easier.
3. Review and Strengthen Employment Contracts
Employment contracts are your first line of defence. They should:
Clearly define confidential information.
Contain enforceable restraint of trade clauses.
Specify notice periods to give you time to manage transitions.
- Clearly define the ‘governing law’ on the employment arrangement.
Include garden leave provisions so employees cannot immediately join a competitor.
With the government planning to ban most non-competes by 2027, it’s more important than ever to review your contracts and strengthen alternative protections.
4. Take Practical Exit Measures
When a senior employee resigns:
Conduct an exit interview and remind them of their legal obligations.
Remove access to company systems and client databases.
Collect company devices, documents, and keys.
Monitor client interactions to detect unusual activity.
When it comes to senior roles, termination can be especially complex – we discuss this further in our article on executive employment dismissal.
5. Seek Legal Remedies if Necessary
If a former employee breaches their contract by joining a competitor or using confidential information, you may seek:
Injunctions to stop them from working for a competitor.
Damages for financial loss suffered by your business.
Enforcement of restraint clauses through the courts.

Prevention is Key
While legal action can protect your business after a senior employee departs, the best approach is prevention. Putting strong measures in place before problems arise is the most effective way to reduce risk and safeguard your business.
At Prosper Law, we recommend that employers:
Implement robust employment contracts and include clear restraint of trade clauses, confidentiality obligations, and notice periods.
Use garden leave provisions, requiring senior employees to serve notice away from the workplace, preventing immediate access to sensitive information before joining a competitor.
Regularly review and update contract clauses to ensure they remain enforceable and relevant to an employee’s seniority and responsibilities.
Train senior staff on obligations to ensure employees understand their duties around confidentiality and post-employment restrictions.
Protect information systems and use secure access controls, monitor data usage, and maintain policies for handling confidential material.
By focusing on prevention, businesses are less likely to face disputes when employees leave – and if disputes do arise, they’ll be in a far stronger legal position.
