Key findings
- A 40-hour job plus 3 hours a day of Flex is 55 hours a week; at 4 hours a day it is 60; at the weekly cap (20 h) it is 60.
- All three exceed the 48-hour average weekly limit in the EU Working Time Directive and the UK Working Time Regulations. Some countries count hours across all employers; others per contract.
- Five clauses decide most cases: outside work, exclusivity, IP assignment, conflict of interest and confidentiality.
- The check is yours to make. PassRidge does not contact your employer and cannot hide Flex work from it.
01The five clauses
Moonlighting is legal in many places, restricted by contract in others, and forbidden by some employers. There is no single rule. Your contract and your country decide, in that order of practical importance.
The five checks below take under an hour. Do them before the skills test, not after the first task.
| Clause | What to look for | Red flag |
|---|---|---|
| Outside work | Whether side work needs consent or notice | 'Any other employment or engagement is prohibited' |
| Exclusivity | Whether you may work for others at all | Full-time exclusive service, even outside working hours |
| IP assignment | What the employer owns: only work for them, or anything you make | Ownership of everything you create while employed |
| Conflict of interest | Competitors, clients and suppliers | A broad definition that covers any QA service work |
| Confidentiality | What counts as confidential and how long it lasts | No carve-out for your own general skills |
02The hours arithmetic
Working-time limits matter once you add hours. The EU Working Time Directive sets an average maximum of 48 hours a week, including overtime. The UK Working Time Regulations set the same figure, which a worker can opt out of in writing. The United States has no general weekly hours cap for most adult employees.
| Scenario | Main job (h) | Flex (h) | Total (h) | Against 48 h |
|---|---|---|---|---|
| Full-time job, one 3-hour task a day | 40 | 15 | 55 | +7 h |
| Full-time job, one 4-hour task a day | 40 | 20 | 60 | +12 h |
| 32-hour week, tasks at the weekly cap | 32 | 20 | 52 | +4 h |
| 24-hour week, tasks at the weekly cap | 24 | 20 | 44 | -4 h |
PassRidge caps Flex at 20 hours a week across all tasks and allows up to 2 tasks at once. The cap keeps Flex as side income. It does not replace your own check of the limits that apply to you, since the rules differ by country and by contract.
03How to keep it clean
Five practices keep the arrangement clean.
- Ask in writing. Email HR or your manager: 'I plan to take occasional independent QA tasks outside work hours. Does this need approval?' Keep the answer.
- Separate everything. Use your own laptop, accounts and test data. Never reuse code, data or documents from your employer. Doing so can breach your contract and the client's NDA at once.
- Avoid conflicts. Tell PassRidge your employer's name and industry at onboarding. We do not assign tasks for your employer, its direct competitors or its clients, or tasks that touch the product you work on.
- Work outside your hours. Do not run Flex tasks during your employer's working time, even if you are remote.
- Keep your own records. Log hours and income. You report contractor income yourself.
PassRidge does not contact your employer and cannot hide Flex activity for you. If your contract requires disclosure, that duty stays with you. See the Flex FAQ.
04Other things to check
Other points to check, depending on your situation:
- Visas and work permits. Some permits tie you to one employer. Self-employed income may not be allowed.
- Inventions and IP. Some places, such as California, limit what an employer can claim on work done entirely on your own time with your own equipment and unrelated to the employer's business. Contract wording still matters.
- Tax and registration. In some countries you must register as self-employed before you invoice.
- Security clearance or regulated roles. Finance, health and government roles often require disclosure of outside work.

05Method and limits
This article is general information, not legal or tax advice. Laws differ by country and change. Read your contract and, if in doubt, ask an employment lawyer.
Hours arithmetic uses PassRidge Flex rules: 3 or 4 hours a day per task and a 20-hour weekly cap across tasks. The 40-hour main job is an illustrative assumption.
