WorkLink Terms of Use

Version 1.1 · Effective November 7, 2026 · Operated by Undongsukje

1. Purpose

These terms set out the conditions and procedures for using the WorkLink app (the “Service”), and the rights and obligations of Undongsukje (운동숙제, “we” or the “Company”), which operates it, and of its users.

2. What the Service does

• Your shift calendar (entered by you) and a view of today’s and tomorrow’s shifts
• Creating shift groups and inviting coworkers, viewing shifts alongside coworkers, and finding shared days off
• Sending and answering swap requests (accept, decline, suggest another day), with notifications
• Weather and air quality for your area, viewing your shifts on a home-screen widget or watch, shift reminders on your phone, counting annual leave days, and (optional) adding your shifts to your phone’s calendar or to a calendar subscription link
• One-on-one chats with coworkers, blocking and reporting
• Connecting your own AI app (optional) — connecting an AI app you use (for example ChatGPT or Claude) to WorkLink to find someone you can swap with within the same shift-sharing group, to send requests and messages that you have confirmed, and to add accepted requests to your own calendar (scope: shift schedule only)

WorkLink does not change shifts for you. Your schedule is finalized by the manager at your workplace (the person who makes the schedule). WorkLink is a personal app for keeping and sharing your own shift records and does not replace your workplace’s official schedule.

3. Fees

WorkLink is free to start. There are currently no ads in the app. We do not charge separately for connecting an AI app; the terms and fees of the AI app you connect are set by the company that provides it. If we introduce paid features later, we will announce them in the app before they take effect, and you will be charged only if you agree directly. We will not turn free features you already use into paid ones without your consent.

4. Eligibility and accounts

• You must be 18 or older. You do not need to be a labor-union member.
• You sign in with Kakao Login, Sign in with Apple (iPhone), Google Sign-In, or LINE Login (in the Japanese version of the app). WorkLink uses the same account as UnionLink (노조링크); if you delete your account in either app, your account in both apps is deleted.
• One person, one account. Do not use someone else’s account or lend yours.
• Use a display name in groups that your coworkers can recognize. You may not use a name that impersonates someone else.
• You can delete your account yourself at any time in the app under “My Info → Delete Account.”

5. Content you add

You keep the rights to the shifts, requests, and messages you add. We use them only as needed to provide the Service and never for advertising. The person who writes a message is responsible for its content. If an unusually large number of messages is sent in a short time, we may limit sending.

6. Prohibited conduct

• Harassing or threatening others, bullying, or persistent picking of fights
• Profanity, insults, hate speech, or discriminatory expressions based on gender, age, origin, disability, religion, sexual orientation, or similar grounds
• Obscene material, sexually offensive text or images, or content that promotes violence or is gratuitously cruel
• Posting other people’s personal information or photos without consent, or defaming others with false statements
• Advertising, promotion, or spamming; using another person’s account or misrepresenting who you are
• Using or disrupting the Service by abnormal means, or breaking the law
• Using an AI connection to create and send messages that deceive or harass others, or calling our servers repeatedly so as to place an excessive load on them
• Copying or spreading outside the group the shifts or names of people in the same group that you read through an AI connection, or using them for any purpose beyond what that person agreed to

7. Reporting and blocking

• If you see an inappropriate chat, let us know with the report button on the chat screen. When you report someone, that person is automatically blocked.
• When you block someone, new messages from that person are not delivered. We do not tell the other person who blocked them. You can unblock at any time in the app.
• We review reports within 24 hours of receiving them. If a violation is confirmed, we remove the content and suspend that user.
• A user who has been subject to action can appeal to help@unionlink.kr, and we will share the outcome within 10 days of receiving the appeal.

8. Zero tolerance and enforcement

We apply a zero-tolerance policy to content and behavior that violate section 6. Depending on severity, we may remove content, limit sending for a period, suspend use of the Service, or delete the account and refuse re-registration.

9. Personal information

We handle personal information in accordance with the WorkLink Privacy Policy.

10. About AI app connections

Answers generated by AI apps can be wrong. When an AI app reads WorkLink data, WorkLink limits it to the scope you allowed (shift schedule only), sends messages to others only after you confirm them on the AI app’s screen, and labels messages sent this way “Sent via AI connection.” Shifts are finally confirmed by your workplace’s official schedule. You can disconnect at any time in the app under “My Info → Connected AI,” and a connection ends automatically after 90 days without use. You can still use every other feature without connecting, with no disadvantage. We make efforts to ensure these limits and confirmation steps work properly, and our liability for intent or gross negligence described below remains unchanged. The answers and processing of the AI app you connect are the responsibility of the company that provides that AI app.

The AI app you connect (ChatGPT, Claude, etc.) is another company’s service that you chose, and that company’s own terms apply separately. Depending on that app’s plan, region, or policies, a connection may not work or some features may be blocked, and we do not guarantee that a connection will work with every AI app. Candidates found by the AI app and “add to my calendar” do not change your ward’s (workplace’s) official schedule, and shifts are finally confirmed by your workplace’s official schedule and your manager’s confirmation. ChatGPT is a trademark of OpenAI, and Claude is a trademark of Anthropic PBC; we are not affiliated with or sponsored by either company.

11. Interruption and termination of the Service

The Service may pause temporarily because of server maintenance, app updates, network failures, or natural disasters. We will announce foreseeable interruptions in the app. If we end the Service entirely, we will announce it in the app and on this page 14 days in advance.

12. Limitation of liability

We make efforts to provide the Service properly. However, we are not responsible for the content of messages users add or for disputes between users arising from it, for problems caused by a user not managing their account, or for problems caused by circumstances beyond our control. If you suffer damage because of our intent or gross negligence, we are liable as provided by law. The fact that the Service is free does not exempt us from this liability. Nothing in these terms limits any rights you have as a consumer under the mandatory laws of the country where you live.

13. Ending the agreement

You can end your use at any time by deleting your account. We may end the agreement if a user repeatedly violates section 6 or uses another person’s identity; we will notify the user in advance and explain why, but in urgent cases we may notify after taking action.

14. Changes to these terms

When we change these terms, we will announce it in the app and on this page starting 7 days before the effective date. Changes that are unfavorable to you will be announced 30 days in advance, and we will ask for your consent again. If you do not agree, you can end your use by deleting your account.

15. Governing law and disputes

These terms are governed by the laws of the Republic of Korea. If a dispute arises, we will first try to resolve it through discussion. If it cannot be resolved and goes to court, the competent court is determined under the Korean Civil Procedure Act. This does not deprive you of the protection of mandatory consumer-protection laws of your country of residence, or of any right to bring proceedings in the courts there where such laws allow.

16. Operator and effective date

These terms take effect on November 7, 2026. This is version 1.1.

Revision history

• November 7, 2026 — Version 1.1 (expanded the service description, prohibited conduct, and notices on AI app connections; expanded the sign-in methods (Google, LINE) and service description (weather, widgets, annual leave, etc.). There is no change that reduces users’ rights, and new features are used only when users separately turn them on, so this version takes effect from the day it is published.)
• November 4, 2026 — Version 1.0 (first version of WorkLink)
