Setting Boundaries at Work: A Practical Guide for Healthy Teams
It's 6:47pm and you're still answering messages that could easily wait until tomorrow. You said yes to a deadline you knew was unrealistic the moment you agreed to it. You've spent the afternoon absorbing a colleague's bad mood as if it were your own. None of these moments feel like a big deal on their own. Add them up over a year, and they're one of the more reliable paths to burnout.
Boundaries are the fix, but the word gets thrown around so loosely it's started to lose its meaning. This isn't about building walls or becoming difficult to work with. It's about being clear, with yourself and the people around you, about what you can sustainably give, and saying so before you're forced to.
What is a boundary at work?
A workplace boundary is a clear limit you set on your time, workload, communication or emotional energy, communicated so the people around you know what to expect. Boundaries aren't about shutting people out — they're what makes it possible to keep showing up, consistently, without burning out.
Most workplace boundaries fall into four categories:
Time boundaries: protecting when you start, finish, and switch off. “I log off at 5.30. I'll pick this up first thing tomorrow.”
Workload boundaries: being upfront about capacity before you're overcommitted, not after. “I can take this on if X moves to next week.”
Communication boundaries: deciding how and when you're genuinely contactable, especially outside working hours.
Emotional boundaries: not absorbing a colleague's or manager's stress as if it were your own.
Why boundaries matter for wellbeing and performance
The World Health Organization's ICD-11 classifies burnout as an ‘occupational phenomenon.’ The organisation describes burnout as a syndrome resulting from chronic workplace stress that “has not been successfully managed.”
That last phrase is the important one. Burnout isn't only a workload problem. It's what happens in the gap left by boundaries that were never set.
There's a legal dimension to this now, too. Since 26 August 2024 (and 26 August 2025 for small businesses), Australian employees have had a right to disconnect under the Fair Work Act, meaning they have the right to refuse unreasonable contact outside working hours. It doesn't ban after-hours emails outright, and “reasonableness” still depends on the role and the method of contact.
How do I say no to my manager without feeling guilty?
Guilt shows up because saying no feels like letting someone down. However, saying yes to everything is what actually lets people down in the long-term, shown more implicitly through missed deadlines, rushed work, or a burnout that takes you out of action entirely. A clear, respectful ‘no’ protects the work as much as it protects you.
A simple structure to use: acknowledge, state the constraint, offer the alternative. For example: “I want to help with X, but I’m at capacity with Y.. how flexible are you with the deadline for this task?”
Example phrases for setting boundaries at work
Time: “I'm logging off at 5.30 — I'll pick this up first thing tomorrow.”
Workload: “I can take this on, but something else needs to move. What's the priority?”
After-hours contact: “I don't check messages after 6pm. If it's genuinely urgent, call me — otherwise it'll have my attention in the morning.”
Emotional: “I can see you're frustrated, and I want to help you think it through — but I can't take this on as my own stress.”
Meetings and interruptions: “I've got a two-hour block this afternoon for focused work — can this wait until after, or does it need me right now?”
The psychology behind a boundary that actually sticks
Most boundary advice stops at the script (i.e., what to say in the moment). The more useful question is why some boundaries hold and others don't, and there's real behaviour-change thinking behind the answer.
Start with noticing. A simple check: is this request green (genuinely fine), yellow (only fine if you actually have the capacity), or red (a hard no)? Most boundary failures happen earlier than people think: not in the conversation, but in not clocking that a request had already tipped into yellow or red before agreeing to it.
How you say it matters just as much. Communication research generally sorts responses into four styles: passive (goes along with it, resents it later), aggressive (pushes back too hard), passive-aggressive (agrees, then complains about it afterwards), and assertive (clear, respectful, and firm). Assertive is the only one of the four that protects both the relationship and the boundary — direct without being harsh, with no room for the request to quietly resurface.
The boundaries that last are also the ones people can explain to themselves. Self-determination theory, a well-established framework in motivation research from psychologists Edward Deci and Richard Ryan, draws a sharp line between behaviour driven by guilt or obligation and behaviour anchored in something you actually value. A boundary held out of guilt (“I feel bad saying no”) tends to collapse under pressure. A boundary held because you know exactly what it's protecting (your health, your family time, the quality of your work), tends to hold.
The most reliable boundary-holders also don't rely on willpower in the moment. They plan the response before the moment arrives. “If my manager messages after 6pm, then I'll reply in the morning” is a stronger boundary than deciding how to feel about it every time it happens, because the decision is already made.
None of this is unique to the workplace. It's the same behaviour-change thinking Better Learning's founder, David Shillington, has spent years applying through his broader work in this space: notice the pattern early, say it clearly, anchor it in something that actually matters, and plan the response in advance rather than negotiating it under pressure every time.
What to do when someone pushes back on a boundary
Pushback is common, especially the first few times you hold a new boundary. A few ways to stay steady without over-explaining:
Repeat the boundary calmly, without adding new justification each time.
Separate the relationship from the request. You can hold a boundary and still be warm.
If a boundary is repeatedly ignored, that's a conversation for a manager or HR, not something to keep absorbing quietly.
For leaders: Building a culture where boundaries are respected
Individual boundary-setting only goes so far if the culture around it quietly punishes people for holding theirs. A few things leaders can do:
Model it. If you send emails at 10pm, don't be surprised when your team feels they should reply.
Ask about capacity before adding to it, rather than assuming there's room.
Treat someone holding a boundary as a sign of good judgement, not a lack of commitment.
The bottom line
Boundaries aren’t the opposite of being a good team player…they’re what makes sustainable teamwork possible in the first place.
Boundary setting isn’t just for individuals. It’s one of the practical levers organisations have for managing psychosocial risk. If you’re responsible for more than just your own boundaries, Be Buoyant is Better Learning’s psychosocial safety training program built to help workplaces turn this knowledge into policy and practice.
Frequently Asked Questions
-
Common examples include logging off at a set time each day, being upfront about workload capacity before taking on new tasks, deciding when and how you're contactable outside work hours, and not absorbing a colleague's stress as your own. The clearest boundaries are specific and stated in advance, rather than reactive.
-
Acknowledge the request, name your current capacity honestly, and offer an alternative. For example, “I want to help with this. I'm at capacity with X — if this is the priority, what should I move?” Framing it as protecting quality and capacity, rather than refusing to help, reduces the guilt.
-
An emotional boundary is the line between supporting a colleague and taking on their stress as your own. It might sound like: “I can see this is frustrating, and I want to help you think it through, but I can't carry this as my own stress.”
-
Since 26 August 2024 (26 August 2025 for small businesses), the Fair Work Act gives employees the right to refuse unreasonable contact outside working hours. Reasonableness depends on factors like how you're contacted, your role, and whether you're compensated for after-hours work.
