Second Jobs and Side Hustles: What Employers Need to Know

With the rising cost of living and the growth of flexible working, more employees are taking on second jobs or “side hustles”. While this is not new, it can create legal, operational and reputational risks for employers if it is not managed correctly.

So, what should employers be aware of when an employee works elsewhere?

Can an Employee have a Second Job?

In most cases, yes. Employees are generally free to work for more than one employer unless there is a clear contractual restriction in place. However, any restrictions must be reasonable and enforceable. Blanket bans are rarely appropriate and may not stand up to challenge. Instead, employers should focus on protecting legitimate business interests, such as confidentiality, conflicts of interest and working time compliance.

Contracts and Policies Matter

Employment contracts should clearly set out expectations around secondary employment. Common provisions include:
• A requirement to disclose other paid work
• Restrictions on working for competitors or clients
• Confidentiality and intellectual property protections
• Requirements not to allow other work to impact performance or availability
Where contracts are silent or outdated, employers may have limited options if issues arise.

Working Time Regulations Risks

Employers remain responsible for ensuring compliance with the Working Time Regulations, including rest breaks and the 48-hour working week (unless an opt-out is in place).
If an employee is working excessive hours across multiple jobs, this can create health and safety risks and expose employers to potential claims. Open conversations and clear declarations are key to managing this risk.

Conflicts of Interest and Confidentiality

Second jobs can sometimes create conflicts, particularly where employees work in similar industries or use skills, contacts or information gained through their primary role.
Employers should ensure conflicts of interest are identified early and that confidentiality obligations are clearly communicated and enforced.

Performance and Wellbeing Considerations

While employees are entitled to work elsewhere, employers can still manage performance. If a second job begins to impact attendance, output or wellbeing, this should be addressed through normal performance or absence management processes.
Ignoring the issue can increase burnout risk and affect wider team performance.

What Employers Should do Now

To reduce risk and maintain fairness, employers should:
• Review employment contracts and policies to ensure secondary employment is addressed
• Introduce a clear declaration process for second jobs
• Train managers to spot potential risks early
• Balance flexibility with clear boundaries and expectations
