Sustainable Performance, Versus the 12-Peak Challenge

There are some businesses and leaders who operate and reward an always-on, kind of hero mindset. I've worked with many people like that. I remember one senior colleague would always clear their inbox on a Sunday, so they'd feel fresh for the week ahead, and in return, you got left feeling behind before Monday even arrived. While there was no explicit expectation to reply, it created a dynamic of being perceived as "on it," keeping up and matching their high pace. On occasion, fine. But when it became the norm, it spiralled a lot of reactive stress through the team and business.

When that leader stopped, there was kind of like an unspoken breath out. People showed up better, with less stress, because they had permission to focus from a place of intentionality rather than react to a JFDI.

It highlights a tension I have experienced and still see everywhere, the gap between what people think drives performance and what actually sustains it.

Everyone has crunch points in a week, a month, a year, moments where peak performance and going above and beyond are totally necessary, and energising. But when those peaks become an expectation, when every month has several new milestones to over-achieve on, it's often the highest performers who suffer. They take on more because they can "handle it," but in reality it becomes burnout disguised as loyal commitment.

When we run from peak to peak, we lose a bit of perspective and ourselves. Losing the capacity to coach and mentor because workloads squeeze out any space for thinking and noticing. Emotional volatility creeps in, with really high highs, can come really low lows, instead of the steadiness that comes from sustainable rhythms. Teams slip into messy survival mode, unable to step back and focus on what matters, and that's where less helpful behaviours can start to mirror your own and show up more visibly. The cost shows up everywhere: culture, productivity, wellbeing, joy, customer experience.

What sustainable performance really means

For me, sustainable performance is about consistency and intentionality. It's having clarity on what priorities are, probably three vs thirty, and understanding how your contribution ladders up to the team, the department and the business. I like the Signal/Noise concept coined originally by Claude Shannon: prioritise the 3 things you must get done in a day, and notice the noise that'll slow it down.

It's not revolutionary, but it's true. I once joined a leadership insight session that simplified performance down to two things businesses need to do well:

• Equip line managers to have effective 1:1s that bring clarity, consistency and coach on the right behaviours.
• Support this with impactful, regular and well-managed performance conversations.

So often I've seen leaders treat both of these as either 1) non-existent or 2) a tick-box exercise. And they will be, if you run them in that way. But the leaders who commit to them, who operate with high challenge and high support, are the ones who drive sustainable high performance.

To make performance sustainable, leaders need to pace themselves and their teams. It's easy to lose sight of this under pressure, I've felt that myself when pressure piles downwards, sideways, upwards, diagonally now I think of it, but regulating emotion, protecting psychological safety and "slowing down to speed up" genuinely pays off. (One of my old bosses will laugh reading, as he used to say this a lot.)

It also means valuing recovery time and recognition as much as the peaks. That might look like encouraging lunch breaks, triaging workloads (who has capacity for stretch and who doesn't), bringing the team together during work hours for a small social or recognition moment, remembering personal moments that matter, leaving on time to get to an exercise class. And it's noticing when someone's pace isn't sustainable, when their sparkle fades, when they go quiet, head down, and holding boundaries that prioritise pace and progress, not relentless pressure.

The cultural conditions that make this possible

Sustainable performance needs some cultural codifying, for example:

• Integrating inclusion and wellbeing into 1:1s, performance reviews and workload triaging. And not treating wellbeing as a perk and benefit held by Reward teams.
• Recognition moments that celebrate wins, quick learns from failure and everyday progress, and not Herculean efforts like "Tim worked for a month without weekends to get this over the line." That kind of praise sends the wrong signal when it's frequent. Although Tim may recognise this was absolutely business critical and take pride in it, for sure.
• Leaders acting as coaches rather than drivers of pressure.

To thrive, people need clarity, challenge, recovery time and headspace for creativity and innovation. Protecting people and culture drives long-term success. Even when it feels tempting to squeeze everything you can in the short term, the performance cost always leaks out at the edges.
