Boundaries, Burnout, and the Cost of Saying Yes

Two Piers Podcast

In this episode of the Two Piers Podcast, Erica D’Eramo is joined by Krista Casey for a conversation about boundaries, highly sensitive people, burnout, negotiation, and what can happen when consistently saying yes becomes unsustainable.

Krista spent more than a decade as a creative director at Fortune 500 companies, including Wayfair and New Balance, leading teams of more than 50 people across the U.S. and Europe. From the outside, her career looked successful, but internally she was overwhelmed, running on empty, and eventually experiencing burnout.

Learning that she was a highly sensitive person gave her language for experiences she had struggled to make sense of. Today, Krista is a certified life and career coach based in Berlin, specializing in helping highly sensitive people design careers and lives that better fit the way they operate.

Her conversation with Erica begins with a familiar word that is often misunderstood: boundaries.

What Boundaries Actually Are

Krista sees two common misconceptions about boundaries.

The first is that having boundaries means being rigid, unapproachable, or unwilling to collaborate. In her view, a well-communicated boundary can actually create more clarity and connection because it gives other people useful information about what you need.

The second misconception is that setting a boundary means telling someone else what they are allowed to do. If someone regularly brings up a topic you find difficult, for example, a boundary is not necessarily, “You are not allowed to talk about that around me.” You ultimately cannot control what another person chooses to say.

The boundary is about what you will do when the situation occurs. Maybe you leave the room, end the conversation, or choose not to participate. Krista simplifies a boundary as a clear statement of your needs within a relationship, situation, or environment.

Erica compares that to an operating manual. A boundary gives other people useful information about how to work with you effectively rather than asking them to guess where your limits are.

Why Self-Boundaries Matter First

Before Krista began studying boundaries, she realized she had spent much of her corporate career without them.

When she left corporate work and moved into coaching, those patterns did not automatically disappear. She carried them with her, which led her to the concept of a self-boundary: a promise you make to yourself and then consistently keep.

For Krista, one example is a weekly sound bath she attends every Sunday. She protects the time, avoids scheduling other commitments around it, and makes arrangements for her son so she can go. The specific activity matters less than the practice of following through.

Over time, keeping those commitments provides evidence that you are willing to protect your own needs rather than treating them as the first thing to be displaced when something else appears.

Erica connects this to something she sees frequently in coaching. Clients value the protected space coaching gives them for reflection and strategic thinking but worry that the space will disappear once the engagement ends. The evidence suggests otherwise: they did make the time when another person was involved. The challenge becomes extending that same level of commitment to time that belongs only to themselves.

The Pattern of Becoming the “Yes Person”

Krista describes herself during her corporate career as a reflexive yes person. She became known as someone who would take things on, often agreeing before the other person had even finished making the request.

Eventually, other people behaved accordingly. If something needed to get done, Krista was a reliable place to put it.

At the time, she did not see herself as helping create that pattern. In retrospect, she can see how repeatedly saying yes taught other people what they could expect from her. That pattern contributed to multiple experiences of burnout.

The dynamic can be particularly pronounced for highly sensitive people. Krista explains that high sensitivity often comes with strong empathy and depth of processing. Someone may quickly notice another person’s anxiety or stress, feel motivated to help, and then spend significant time processing the interaction afterward.

That combination can make an automatic yes particularly tempting. It can also lead to second-guessing: perhaps I should take this on, maybe I am not doing enough, maybe this person really needs me.

Without a pause, those thoughts can move directly into another commitment.

Start With a Pause

For someone who habitually says yes, Krista does not recommend trying to transform overnight into someone who immediately says no. The first step is much smaller: pause.

Instead of answering immediately, acknowledge the request and create enough time to consider it. That might sound like, “Thanks for thinking of me. Let me look at my priorities and capacity, and I’ll come back to you tomorrow.”

The exact language is personal. What matters is interrupting the automatic response.

That brief pause creates room to ask better questions: Do I actually have capacity for this? Does it align with what I am responsible for? What would I have to move, delay, or give up in order to say yes?

Those questions lead into another concept Krista uses with clients: the “yes cost.”

Understanding the “Yes Cost”

Every commitment costs something. It might cost time, energy, attention, or mental capacity. Because capacity is finite, taking on something new usually has implications for something else.

Krista suggests evaluating a request through three filters: alignment, capacity, and tradeoffs.

First, does the request align with your actual priorities, goals, or responsibilities? In a workplace, that may mean looking at formal goals, OKRs, scope, or the work your role is intended to prioritize.

Second, do you realistically have the time and energy to take it on? This is different from asking whether you could somehow force it into the schedule.

Third, if you say yes, what needs to move?

This is where a boundary often becomes a negotiation. Rather than simply refusing the request, someone might say, “I can prioritize this, but that would mean parking these two projects for the next six weeks. Does that make sense given our priorities?”

Now the capacity problem is visible instead of silently absorbed.

Boundaries and Negotiation Are Closely Connected

Krista describes negotiation simply as “a conversation about what’s possible.”

That framing moves the conversation away from the assumption that negotiating means arriving with a hard demand and refusing to move. Once you know where your boundary is, you can begin exploring options.

Maybe you can take on the new project if something else is postponed. Maybe part of the work can be delegated. Maybe the scope changes. Maybe the deadline moves.

Erica connects this to coaching because many of the same open-ended questions used in coaching are useful in these conversations: Where does this sit among our current priorities? If we cannot do everything at once, which item should come first? What could be delegated? What tradeoff are we willing to make?

Those questions create a conversation about the work rather than forcing an individual to quietly absorb an impossible workload.

Why Standard Negotiation Advice Doesn’t Always Fit

Krista also points out that negotiation happens within a social context.

A simple instruction to “be confident” or “just say no” may ignore the consequences people have experienced when they behave that way. She specifically discusses the backlash women can encounter when they use the same direct negotiating behaviors that may be rewarded in men.

Women are often expected to be collaborative and accommodating. A direct refusal may therefore be interpreted differently depending on who delivers it.

For Krista, this does not mean women are inherently worse negotiators. It means that some common negotiation advice was developed without accounting for the different risk landscape women may be navigating.

Highly sensitive people may be taking in even more information during those conversations: tone of voice, facial expressions, changes in energy, pauses, or other signals from the people around them. That amount of processing can make negotiation cognitively and emotionally expensive.

The goal is not to ignore those signals, but to develop strategies that allow someone to advocate for themselves while still navigating the context they are actually in.

What Happens When Boundaries Are Missing at Work

The effects of weak boundaries do not stop with the individual.

Krista describes reaching burnout while leading a team of more than 50 people. When she eventually needed to step away for around 10 days, her absence was destabilizing for the department.

That made the systemic problem much clearer. Being the person who always says yes can look like reliability right up until the system becomes overly dependent on that person.

The same behavior also gets modeled downward. Krista noticed members of her team beginning to replicate her own pattern of overwork because, as their leader, she was showing them what success appeared to require.

Erica shares a similar experience from her time working offshore. Because of severe jet lag, she sometimes stayed up working late into the night. Her manager eventually pointed out that her team could see her working and did not know she was simply unable to sleep.

They interpreted her behavior as an expectation.

He asked whether she had noticed that when she stayed up late, other people stayed up late too. She had not.

For both Erica and Krista, seeing the effect on other people made the consequences of their own work patterns more visible.

Leaders Model More Than They Realize

People watch leaders for cues about what the organization actually values.

Formal policies may say one thing, but leaders communicate norms through what they reward and what they visibly do themselves. If the leader routinely works late, responds immediately, takes on everything, and never appears to protect their own capacity, employees may reasonably conclude that this is what advancement or commitment looks like.

That makes boundaries an organizational issue as much as a personal one.

Krista recalls being praised for staying late and consistently overextending herself. The recognition reinforced the behavior, even though the behavior was ultimately unsustainable. When the team began copying it, she could see the broader consequence more clearly.

Communicating Capacity Before Something Breaks

One challenge with highly reliable people is that organizations may have little visible evidence that anything is wrong until that person reaches a breaking point.

Erica compares this to material science. Some materials show deformation before they fail. Others remain apparently stable until they suddenly break.

People can operate similarly.

Someone who has always managed to get the work done may finally tell a leader, “I don’t think this is sustainable,” only to hear, “We believe in you. You always figure it out.”

The intended message may be supportive, but it can also ignore important information about capacity.

Krista describes learning to recognize her own warning signals after experiencing burnout and becoming faster at communicating when her scope was no longer manageable. Again, the conversation becomes a negotiation: here is my current scope, here are some options for bringing it back into alignment, and here are the tradeoffs involved.

She also notes that successful negotiation often happens across several discussions rather than in one decisive meeting.

Testing a Boundary Gives You Information

What if you genuinely believe the environment will not respect a boundary?

Krista does not dismiss that concern. Instead, she often encourages clients to test it.

Choose a smaller boundary rooted in something that genuinely matters and observe what happens. Maybe the response is easy acceptance. Maybe the boundary is immediately rejected.

Either way, you have learned something.

If reasonable boundaries are repeatedly ignored or punished, that is useful information about the environment itself. Rather than spending months or years making assumptions about what might happen, testing a boundary can provide actual evidence.

That evidence allows someone to make more informed decisions about whether the environment can become sustainable, whether further negotiation is possible, or whether they may eventually want to explore other options.

Boundaries as a Tool for Clarity

By the end of the conversation, boundaries look considerably less like walls and more like a way of communicating needs, understanding capacity, clarifying tradeoffs, and negotiating what is actually possible.

For people who have spent years being rewarded for saying yes, changing the pattern may begin with something as simple as not answering immediately.

The goal is not to become less collaborative or less caring. It is to develop a more sustainable way of working that allows people to contribute without making themselves the expendable part of the system.
