Every candidate I place has to do the one part of the process I can't do for them: walk into their manager's office and resign. Plenty of experienced salespeople who can hold a room of architects go quiet when I ask how they're planning to handle it.
Fair enough. It's an awkward conversation with someone who probably hired you, backed you, and is about to have their week ruined. This is the playbook I talk candidates through before every resignation, refined by watching hundreds of them go well and a handful go very badly.
Why does how you resign matter so much in building products?
Because the industry is small and long-memoried, and the manager you resign from will cross your path again. They'll turn up as a reference, a client, a competitor, or the hiring manager at a company you want to join in five years. Suppliers merge, people move between competitors constantly, and reputations travel through the channel faster than CVs do.
I ran pubs for ten years before recruitment, and hospitality taught me the same lesson at higher speed. The staff who resigned properly could ring me years later and get a shift, a reference, or a referral. The ones who walked out mid-service got remembered too, just differently. Building products works the same way, just on longer cycles.
When should you resign?
After you've signed the new contract, and never before. A verbal offer is a mood, and moods change. Wait until the written contract is signed by both sides, your start date is agreed, and any conditions like medicals or reference checks are cleared. Then resign.
Resigning on a verbal offer is the most avoidable disaster in job changing. I've seen offers shift on start date, package, and in one case disappear entirely between the phone call and the paperwork. The candidate who has already resigned has no floor under them while that happens.
How do you actually have the resignation conversation?
Face to face or by phone, with your direct manager, before anyone else knows. The order matters. A manager who hears it from you directly gets to keep their dignity. A manager who hears it from the state grapevine, or worse from LinkedIn, starts the conversation embarrassed and defensive, and embarrassed people make poor allies for the next five years.
Keep the script short and warm. Something like: "I wanted to tell you first. I've accepted a role elsewhere and I'm handing in my notice. This wasn't a quick decision, and I want to use my notice to hand everything over properly." Then stop talking.
Two things to hold onto in the room. First, you don't owe a full explanation of where you're going or why, and volunteering grievances in the resignation meeting achieves nothing a handover can't undo. Second, gratitude costs nothing and pays for years. If the company gave you your start, your training, or your best territory, say so.
What should the resignation letter say?
Three things: that you're resigning, your final date based on your notice period, and a line of thanks. That's the whole letter. It's a legal document confirming dates, and every extra sentence is a liability with no upside.
The letter is never the place for feedback, grievances, or an essay on your journey. If the business wants your honest views, there's an exit interview for that, and even there the smart play is honest, brief, and constructive. Nothing said in an exit interview has ever fixed a company, and plenty said in exit interviews has followed people around an industry.
How do you handle the notice period?
Treat it as the longest job interview of your career, because that's what it is. Everyone watches how a resigned employee behaves, and the impression you leave in those final weeks overwrites years of the impression that came before. Turn up, work your pipeline honestly, and build the handover document you'd want to inherit: live opportunities and their stages, key contacts and their quirks, pricing history, open quotes, project pipelines, and where the bodies are buried on problem accounts.
Leave your LinkedIn alone until you've started the new role. Updating your profile or announcing the move during notice tips off clients and competitors before your employer has a transition plan, and it's the single most common notice-period mistake I see. I've written a full guide on the sequencing in What to do with your LinkedIn after you accept a new sales role.
And know where the lines are. Client lists, quote histories, and pipeline data belong to your employer, and taking them is the fastest way to turn a clean exit into a legal one. If you have a restraint clause, read it before you resign, and get advice if it's broad. There's a full breakdown in Non-Competes for Building Products Sales Reps.
What do you do when the counter-offer comes?
Expect it before you resign, and decide your answer before you're in the room. In this market, any employer losing a rep with real specifier relationships will at least think about countering, and the conversation goes better when you've already done your thinking. If your decision is made, thank them and hold it in one sentence, without reopening the negotiation.
Counter-offers deserve their own post, and they have one: Counter-Offers in Building Products Sales: What Happens After You Say Yes. The short version is that most of them solve the employer's timing problem rather than the reasons you resigned.
What should you never do on the way out?
Don't ghost the notice period or coast through it visibly. Don't announce the move on LinkedIn before you've left. Don't tell clients you're leaving before your manager has a transition plan, however tempting the relationships make it. Don't take data. Don't recruit your colleagues on the way out the door, whatever you privately hope happens later. And don't torch anyone in the exit interview, because the person you torch will know within the week in an industry this size.
Call it self-interest with a long horizon. The handful of candidates I've watched burn the exit all met the consequence eventually, usually years later, in a reference call or an interview they never knew they lost.
