Why Side Projects At Work Are The Fastest Path To Promotion
(When You Pick The Right Ones)
Not all extra work is created equal.
A coaching client came to me last spring, exhausted. She’d said yes to three side projects at work in the last year. She’d rewritten the onboarding deck for new hires, joined a committee on culture, and stepped up to run the summer intern program. She’d worked nights and weekends to deliver all three. Her mid-year review had just come back the day before we spoke. Her rating hadn’t moved. Her promotion timeline hadn’t moved. Her boss had thanked her for being such a team player.
She said the phrase back to me flatly. Team player. Like she was hearing it for the first time even though she’d been called it for years. She’d spent a year saying yes and had earned herself the exact reputation she didn’t want.
What Most People Get Wrong
The advice you’ve heard your whole career is that volunteering for more work is how you get noticed. Take on the extra thing. Say yes when nobody else will. Be the person who steps up. That’s the story most young professionals believe when they walk into their first corporate job.
There’s something in the advice that’s true. Volunteering does get you noticed. What nobody tells you is that being noticed by your peers or your boss’s peers isn’t the same as being noticed by the people who actually decide what happens to you next. Most side projects at work are visibility traps. They keep you busy, tire you out, and build a reputation for reliability at the wrong level. You get thanked. You don’t get promoted.
I know this because I’ve been on both sides of the desk. I’ve watched high performers on my team say yes to every side project that came across their desks and quietly lose ground. And earlier in my career I fell into the same trap myself. It took me longer than I’d like to admit to figure out that “team player” was another word for “convenient.”
The One Rule
Here’s the rule that changes which side projects you say yes to and which you politely decline.
The right side project puts you in a room with a senior decision-maker who wouldn’t otherwise know your work.
That’s it. If a project doesn’t clear that bar, it’s a favor to the person who asked, not a lever for your career. The onboarding deck, the culture committee, the intern program. Those are all valuable to the company. None of them put you in a room with anyone who decides what happens to you next.
Run this test when you’re offered an extra project. Ask one question. “Who from senior leadership will see this work directly, and in what setting.” If the answer is a specific senior leader in a specific meeting, that’s the project worth losing sleep over. If the answer is a name at your own level, or a vague “senior stakeholders will be updated,” decline warmly and move on.
The Second Story
A different client, same year. She was in a mid-size insurance company, three years in, senior individual contributor. Her boss’s boss had just gotten pulled into a strategic review that needed someone to build the analytics model over six weeks. Two people on her team had been asked. Both declined because they were slammed. She had capacity but not the invitation. She reached out to her boss’s boss directly with one sentence. “I heard the strategic review needs an analytics model. I’ve built one like this before. I can start Monday.”
He said yes the same day. The first draft of the model came back with a page of comments, and she rebuilt it over a weekend. In her second presentation to the senior team, one of the SVPs pushed back hard on her assumptions, and she almost got defensive before catching herself and asking him to walk her through his concern. She left that meeting shaken and rewrote three slides that night. By the end of the six weeks, she had two senior stakeholders who had seen her work up close and one who had watched her handle heat in the room from an executive.
The language in her mid-year review the following January had shifted. Not “team player” anymore. Different words. Words about readiness and strategic partnership. She got the promotion five months later.
I want to be honest about the other version of this too. Years ago, in my own career, I took on a side project that fit exactly this rule. It gave me real credibility with senior leaders and put me in rooms I wouldn’t have been in otherwise. Then my company was acquired. The senior leaders who had seen the work were gone. The new leadership team had no context for what I’d done or why it mattered, and I couldn’t get the value of that project to carry through. The rule still worked. The reward didn’t survive the transition.
That’s the part nobody puts in the promotion advice. Sometimes you do the right thing and the environment changes and you have to build the credibility again from scratch. The rule is still the right rule. Just don’t expect it to be the last time you’ll need to apply it.
What The Rule Protects You From
Here’s the part nobody says out loud. Most side projects at work exist because someone senior needed something done and didn’t want to pay for a headcount to do it. The onboarding deck, the culture initiative, the process improvement group. These are real needs, and someone has to do them. But the person who does them is doing free labor for the company, not building their own reputation.
The rule keeps you out of that trap. Not because you’re too good for the work. Because your time is finite, your energy is finite, and you only get so many “extra project” bullets on your resume before you burn out. Spend them in rooms where they compound. Skip the rooms where they don’t.
Your Turn
What’s a side project you said yes to last year that you’re not sure paid off? Or one you’re being offered right now that you’re on the fence about. Drop it in the comments if you’re willing. Some of the most useful patterns in coaching come from watching what people almost took on.
I work with eight 1:1 coaching clients at a time. Mostly young professionals who are exhausted from saying yes to the wrong things and ready to be strategic about the right ones. Reply if that’s you.
