A few years back I missed my son's school play because of a release deadline. Standard story. The deadline was fine. The play happened. The world kept turning. Years later I asked him about it and he remembered every detail of the night and exactly where I was not.
I had no boundary. I had a calendar with my priorities written by other people.
Boundaries get a bad rap. Workplace language treats them as soft, defensive, almost childish. As if a grown person should be available always and grateful for the privilege. The truth is the opposite. Setting a boundary is one of the most rebellious things you will do in a job.
The Always-On Tax
Look around at your work life. The Slack notifications at 11 PM. The Sunday emails marked "no rush" and sent anyway. The meeting invite for 7 AM Pacific because someone in another time zone needed it. The implicit promotion criteria of "responsive."
None of this is in your contract. All of it is the price you pay for not pushing back.
A 2021 study in the Journal of Psychosomatic Research followed thousands of people over a decade and measured how their sense of purpose changed. Across three populations ... almost 2,700 White Americans, 248 African Americans, and 644 Japanese adults ... purpose declined as people aged. Around one in eight reported a meaningful drop. Only one in fifteen reported a rise.
The people who held onto purpose had measurably better physical health. The ones who lost it did not.
You are watching the cost of erased boundaries play out, at scale, in a peer-reviewed dataset.
Boundaries Are Not Walls
The word gets misused. People hear "boundary" and picture a moat. A flat refusal. I do not work past five and I do not answer email on weekends, full stop.
A flat refusal is one kind of boundary. It is not the only kind.
A boundary is information. It tells the people around you what your yes means and what your no means. Without one, your yes is worthless because it has no edge. If you agree to everything, your agreement is a reflex, not a choice.
The most effective boundaries I have set in my career were not refusals. They were declarations. I will lead this project, and the launch date is non-negotiable on these dates ... here is the family event ... so let me know now if the schedule needs to shift. The team got more from me, not less. They got a leader who told them where the edges were.
The colleague with no boundaries is the one nobody trusts with a hard problem. Because they say yes to everything, they finish nothing well.
Why It Feels Rebellious
Kelly Swingler called boundaries "the ultimate rebellion" and the word fits. Modern work culture rests on a quiet assumption ... your time, your attention, and your stress tolerance are infinite. Any limit you put on them is treated as a defect to manage.
I have been told, in different rooms across different decades:
- You are not a team player.
- We need someone with hunger.
- This is a high-performance culture.
- If you want to grow, you have to be available.
Each phrase translates to the same instruction. Hand over your edges. Let the company decide where you end.
The rebellion is not setting the boundary. The rebellion is keeping it once it pisses someone off.
The 6% Tell
Anthropic analysed a million Claude conversations and found six percent of them were people asking the AI for personal guidance. Of those, twenty-six percent were career questions. Run the math. Tens of thousands of people sitting at their desks asking a chatbot what to do with their working lives.
They are not asking because their boss is mean. Some are. Most of them have lost their boundaries one Slack message at a time, and the only one left to set is the resignation letter.
A resignation is a boundary you set when you waited too long.
Five Boundaries I Use
Not theory. Things I do, with words I have used.
The morning lock. From 6 AM to 9 AM, my phone does not pull email or Slack. The hours go to my thinking, my writing, and breakfast with the people in my house. If the company collapses in those three hours, it was going to collapse anyway.
The "ask twice" rule. If a stakeholder pushes back on a no, I hear them out and decide again. If they push a third time, the answer goes from no to never. People who respect your edges ask once. People who do not are training themselves to wear you down.
The Friday vow. I do not commit to anything new on a Friday afternoon. My brain is fried, my judgment is poor, and Monday me is paying the bills. The yes I give at 4 PM Friday is a yes I almost always regret.
The "phone in the drawer" hour. When I am with my grandson, the phone goes in a drawer in another room. Not face down. Not on silent. Out of sight. I have lost two business calls this way over five years. I have gained five years.
The truth budget. I tell one hard truth a week to someone who needs to hear it. Boundaries are not only about what you withhold. They are also about what you refuse to swallow. A relationship where you withhold the truth is a relationship with no edges, and it will rot.
The Hidden Cost of No Boundaries
Companies frame boundaries as a personal indulgence. As if you are demanding a perk. The math runs the other way.
The person with no boundaries makes bad decisions. They commit to too much, deliver late, burn out their team, and quit at the worst possible time. The cost of replacing a senior leader is somewhere between half and twice their salary, before you count the projects stalling while you hire.
The person with strong boundaries makes the company more money over a longer time horizon. They say no early so they say yes well. They protect their judgment. They sleep. They show up.
If you are a manager and you find yourself frustrated by a team member who guards their edges, ask yourself who pays the bill when those edges disappear. The answer is you, six months later, when they leave.
How to Start
If this is foreign territory, do one thing.
Pick a single recurring thing in your week which drains you and has no good business reason to exist. The status meeting nobody owns. The Sunday email triage. The Saturday morning "quick sync" with the founder who likes to think out loud.
Name it. Tell someone you are dropping it. Do not apologize. Do not over-explain. Apologies invite negotiation, and you are not negotiating.
See what happens. Almost nothing will. The world is wider than the people who have been crowding into your time.
Once you survive the first one, set the next.
The Question
If you took an honest look at your calendar this week, how much of it is the life you said you wanted, and how much is the residue of every time you did not push back?
The good news is your calendar is not a contract. It is a draft. Boundaries are how you edit it.
