With the cost of living still front of mind and remote work more common than ever, more people in Scotland are taking on more than one job. Sometimes it’s a side hustle. Sometimes it’s two part-time roles. In some cases, it’s juggling two remote jobs at the same time.

This kind of working arrangement is often called moonlighting or Polygamous working, and while it’s not automatically illegal, it does come with rules, risks and responsibilities that jobseekers need to understand.

Here’s what working more than one job really means in Scotland, what’s allowed, what can land you in trouble, and how to protect yourself.

---

Is it legal to have more than one job in Scotland?

In short: yes, it can be.

There’s no law in Scotland that says you can only have one job. Many people legally work:

• A full-time job and a part-time job
• Multiple part-time roles
• A PAYE role alongside self-employment

The problems don’t usually come from having two jobs – they come from how those jobs interact.

When working two jobs becomes a problem

1. Your contract says you can’t

Many employment contracts include clauses about:

• Exclusivity (you can’t work elsewhere)
• Needing permission for additional work
• Conflicts of interest

If you ignore these and take on another role anyway, you could be breaching your contract – even if the work happens outside your normal hours.

2. Working hours break the law

Under the Working Time Regulations, most workers shouldn’t work more than 48 hours a week on average (unless they’ve opted out).

That limit applies across all jobs combined, not per employer.

Fatigue, burnout and performance issues are often what alert employers that something isn’t right.

3. Two jobs, same hours

This is where things get risky.

If you’re being paid by two employers for the same working hours – particularly in remote roles – that can cross the line into misconduct or fraud, even if the work is getting done.

Employers expect your time and attention during paid hours. Quietly running two jobs at once without agreement can lead to dismissal.

4. Conflicts of interest

Working for competitors, clients, or businesses with overlapping interests can create legal and ethical issues – even if the roles feel unrelated.

Tax and HMRC: what you need to watch

Having more than one job isn’t a tax problem in itself, but you need to make sure:

• Your tax codes are correct
• You’re paying the right amount of tax across all income levels
• Any self-employed income is declared

HMRC doesn’t mind how many jobs you have – they do mind if income isn’t reported properly.

Being open vs staying quiet

Some people worry that telling an employer about a second job will hurt their chances. In reality, problems are far more likely if it comes out later.

Being upfront allows employers to:

• Flag genuine conflicts early
• Agree on boundaries around hours and availability
• Protect both sides if questions come up

That doesn’t mean oversharing – just being honest where contracts or working hours are affected.

How to protect yourself if you’re considering a second job

Before you accept another role, ask yourself:

• Does my contract allow this?
• Will the hours clash, even occasionally?
• Could this affect my performance or wellbeing?
• Am I being paid twice for the same time?

If the answer to any of these gives you pause, it’s worth slowing down and getting clarity.

Final thought on working more than one job

Working more than one job isn’t new – but remote work has changed the rules of visibility and trust.

Done transparently and within the rules, having multiple jobs can be a smart, practical choice. Done quietly and in conflict with your contract, it can put your income and reputation at risk.
