"Set boundaries" is the most frequently given and least frequently explained piece of work advice in circulation.
Everyone says it. Nobody tells you how.
That gap, between the advice and the reality, is where most people live. Knowing they should do something and having no idea how to actually do it without it becoming a whole thing.
This is the actual version.
Why setting boundaries at work is hard.
The workplace is specifically designed to make it difficult.
Your job comes with implicit expectations that were never written down anywhere. You're supposed to be responsive. Available. Flexible. These words don't mean anything specific but they create a general pressure to never quite say no, never quite be unavailable, never quite put a limit on what you'll give. And if you push back on any of it, there's a word for that too. Difficult.
The other thing that makes it hard: most people need the job. The mortgage exists. The direct debits exist. Setting a boundary with an employer you depend on financially is not the same as setting a boundary with a friend. The power is uneven. Pretending otherwise doesn't help.
So the advice needs to work in the real world. Not the self-help version where you confidently declare your limits and everyone immediately respects them. The actual world, where you still have to sit next to these people tomorrow.
What a boundary at work actually is.
A boundary is a decision you make about what you will and won't do, communicated clearly enough that other people know where the line is. That's it. It doesn't have to be dramatic. It doesn't have to involve a difficult conversation. Some boundaries are never spoken at all, they're just practised, until they become the expectation.
The mistake most people make is confusing a boundary with a request. A request is "I'd prefer not to get emails after 6pm." A boundary is not checking emails after 6pm. One requires the other person to change. The other just requires you to.
That distinction matters. Because you cannot control what other people do. You can only control what you do in response.
Examples of boundaries at work that actually work.
Not checking emails after a certain time. You stop checking. If something is genuinely urgent, people will find another way to reach you. If they don't, it wasn't urgent.
Not being available outside contracted hours. Your contracted hours are the thing you agreed to sell. Time outside those hours belongs to you. Taking work calls on your day off, answering Slack messages at 10pm, responding to things on holiday, none of this is contractually required, and all of it trains people to expect it. Once you've established that you're always reachable, you've made that the norm. It's much harder to walk back than to never establish in the first place.
Saying no to things that aren't yours. The extra project that keeps landing on your desk. The work that technically belongs to someone else but somehow always ends up with you. "That's not something I'm able to take on right now" is a complete sentence. It doesn't need justification. It doesn't need an apology. It needs to be said, clearly, and then not walked back when someone looks disappointed.
Not performing enthusiasm you don't feel. This is a quieter one. But the energy you spend pretending to care about things you don't care about is real energy. The performance of engagement in meetings where nothing will be decided. The manufactured excitement about initiatives that won't change anything. You don't have to be visibly cynical. You also don't have to perform.
Setting boundaries with your boss specifically.
This is where it gets more complicated, because the power dynamic is real and the consequences of getting it wrong are real.
The most useful thing you can do with a boss who has poor boundaries is make the implicit explicit. "I want to make sure I understand what's expected — is responding to messages in the evening something that's required for this role?" puts it on the table. Most managers, when asked directly, will say no. And now you have something to point to.
Document things that feel like overreach. Not because you're building a legal case, though that's occasionally necessary, but because patterns are easier to see when they're written down. And because memory is unreliable under stress, and you need to be able to say "this has happened four times in the last month" rather than "I feel like this happens a lot."
Pick the boundaries that matter most first. You're not going to change everything at once. Start with the one that's costing you the most. The late-night emails. The weekend calls. The meetings that keep being scheduled over your lunch. One thing, consistently held, is more effective than five things held erratically.
The guilt.
Most people who struggle to set boundaries at work aren't struggling because they don't know what they want. They're struggling because saying no feels selfish. Because being unavailable feels like letting people down. Because somewhere along the way they absorbed the idea that their value at work is measured by how much they give and how rarely they say no.
That's conditioning. And it's worth examining where it came from and whether it's actually serving you.
Your employer is not your family. Your colleagues are not your responsibility to the exclusion of yourself. The company will not protect you from burnout out of loyalty, it will take what you offer until you stop offering it. That's just how it works.
Protecting your time and energy isn't selfish. It's the thing that allows you to keep functioning. For yourself first. And yes, as a side effect, for the job too.
Write it down.
If you're not sure where your limits actually are, start there. What are the things that, when they happen, leave you feeling depleted and resentful? Make a list. Those are your signals. Then work out which of them you have any practical ability to change.
The Dead End Desk Survival Guide and the Survival Journal work well together here — the book gives you the framework, the journal gives you somewhere to track what's actually happening, which is the first step to doing something about it.
And if you want something that says what you actually think about all of this — we've got that too.
One last thing.
The goal isn't to become someone who never gives extra. The goal is to stop giving extra by default, automatically, without it being a choice. To make it a decision rather than a reflex. So that when you do go above and beyond, it means something — to you and to whoever benefits from it.
You can't pour from an empty cup. You also can't pour from a cup that everyone else keeps helping themselves to without asking.
