What to do if…
you lose access to your work email and systems without warning
Short answer
Pause and assume it could be a security hold, an IT problem, or a suspension. Use a neutral channel (phone/text) to contact your manager and your IT/service desk, and ask for clear written confirmation of what’s happening and what you should do next.
Do not do these things
- Do not try to “work around” access controls (personal email, personal cloud storage, colleague logins, forwarding rules, remote tools) — that can look like misconduct or create a security incident.
- Do not repeatedly guess passwords, use random “password reset” links, or sign in on unfamiliar pages — it can worsen a lockout or aid phishing.
- Do not delete messages or wipe your work device “just in case”.
- Do not post about it publicly, or message lots of coworkers for explanations — it can escalate things and create misunderstandings.
- Do not resign in the moment or send an angry message you can’t take back.
What to do now
- Stabilise and capture the basics (2 minutes). Write down: the time access stopped, what exactly you can’t access (email/VPN/HR portal), and any error messages (photo/screenshot).
- Use an “outside” channel to contact the right people. From your personal phone/email (or a known non-work channel you already use with them), message:
- Your line manager: “I’ve suddenly lost access to my work email/systems. Can you confirm if this is an IT/security issue or something else, and who I should speak to?”
- Your IT/service desk (or security team if you have one): “My account appears inaccessible. Please confirm if it’s locked for security and advise the official reset/verification steps.”
- Treat it as a possible security incident until told otherwise.
- If you recently clicked a link, approved a sign-in, or entered a password somewhere unusual, say so to IT/security right away.
- Stop using the same password anywhere else: change passwords on your personal accounts only if you reused the same (or very similar) password.
- If the suspicious message was on a personal email account, you can forward it to report@phishing.gov.uk. If it was a suspicious text message, you can forward it to 7726.
- If you’re told you’re suspended or under investigation, switch to “paper trail mode.”
- Ask for written confirmation (letter, or to a personal address if they’re able) of: whether you are suspended, from when, whether it is paid, and who your HR contact is.
- Ask what you are allowed to do while locked out (for example, whether you can contact colleagues, and how you’ll be contacted about meetings).
- Check your contract/handbook for suspension/IT access wording, but don’t argue in real time — focus on getting clear instructions in writing.
- If you’re told your employment has ended (or you strongly suspect it has), keep it calm and practical.
- Ask HR for a short written statement of your employment status and how you’ll receive pay owed (including outstanding wages/holiday pay if applicable) and your P45 if employment has ended.
- Ask how to return company property (laptop, badge) safely and how you’ll receive any personal belongings (if relevant). Don’t hand anything over “informally” without a record.
- Protect yourself from “quiet pressure.” If anyone asks you to accept blame, sign something, or “confirm resignation” on a call, say: “I’m not able to agree to anything right now. Please send it to me in writing and I’ll respond.”
What can wait
- You do not need to decide today whether to raise a formal complaint, resign, or take legal action.
- You do not need to start any external process immediately. If this becomes a dispute that might go to an employment tribunal, there are formal steps (including contacting Acas for early conciliation) — that can come later, once you know the facts.
- You do not need to “fix your reputation” by messaging colleagues. Keeping communications minimal is usually safer until you have clarity.
Important reassurance
A sudden lockout is genuinely alarming, and it often happens for ordinary reasons (security precautions, automated account controls, IT outages, admin errors) as well as more serious ones. The safest first move is to slow down, avoid workarounds, and get a clear written explanation through the proper channels.
Scope note
This is first-step guidance to stabilise the situation and avoid irreversible mistakes in the first hours. Once you know whether this is IT, a security hold, suspension, or termination, you may need more tailored employment advice.
Important note
This is general information, not legal advice. Workplace procedures and rights depend on your contract, policies, and the specific facts. If you feel pressured, threatened, or unsure what you’re allowed to do while locked out, get independent advice before taking irreversible steps.
