Yes. A faxed resignation letter counts as written notice, and the medium is not the issue. The parts that matter are timing, clarity, and proof. Keep the fax confirmation page showing the date, time, recipient number, and successful transmission, and give whatever notice your contract or handbook requires.
| Channel | Strengths | Weaknesses |
|---|---|---|
| In person, then in writing | Best etiquette; protects references | No paper trail unless you follow up |
| Fax | Written record with a dated transmission report | Can seem abrupt; confirm the right fax number first |
| Timestamped; easy to keep a copy | Can be missed or land in spam | |
| Printed letter | Most formal; physical proof via certified mail | Slowest to arrive |
In most U.S. states, employment is at will, which means you can resign at any time with no legal notice requirement, and your employer can do the same. Canada works similarly for most non-union roles, with reasonable-notice norms built up through case law rather than statute. The real constraints are usually contractual: your offer letter, employment agreement, or handbook may ask for two weeks and may define what "written notice" means. A few industries (healthcare, childcare, some licensed trades) have their own expectations around handoff. Check your own documents before you pick a channel; if your agreement says notice must be in writing, a faxed letter satisfies that on paper.
Fax makes sense when the recipient still runs on fax: some government offices, union halls, franchise headquarters, and small businesses genuinely do. It also helps when you need a transmission report for your records, for example if a benefits cutoff or a severance trigger is tied to the exact date notice was given. The non-obvious risk is a wrong number: a fax to the wrong machine goes to a stranger's tray with your name and signature on it. Call the office first, confirm the fax number with a person, and send a test if the number matters to you. Then keep the confirmation page; it is your receipt, the equivalent of a mailing slip.
Short beats thorough. State that you are resigning, name your role, and give your last working day. One or two sentences of thanks keep the door open. Skip detailed reasons: they do not help you and they create a written record you cannot take back. A concrete example of the exactness that matters: if your handbook asks for two weeks and you want your last day to be a Friday, count the business days yourself rather than writing "two weeks," since holidays can shift the real date. Sign the letter before you fax it; an unsigned resignation invites questions you do not need.
The confirmation page is your primary evidence: it typically shows your sender ID, the recipient's fax number, the date and time, the number of pages, and a result code like "OK." Save it the same day, ideally as a scan. Two things that strengthen it further: faxing during business hours (a 2 a.m. transmission to an unmonitored machine weakens your claim that anyone saw it) and a brief follow-up, by phone or email, confirming receipt. If the stakes are high, a mailed letter with tracking alongside the fax gives you two independent proof channels.
