Your strongest managers are starting to burn out, and a big part of the problem comes down to decision fatigue. This 2026 Insight Report from W Talent takes a closer look at the mental strain your managers are dealing with behind the scenes, the knock-on effect it is having on business performance, and a clear four-part framework you can use to sort it out.

Over the last year, one trend has started showing up far too often to brush aside. Strong, ambitious managers, the very people businesses have invested serious time and money in bringing on board, are running out of steam just 12 to 24 months into roles that once looked full of promise.

They are not coming unstuck because they are short on ability or work ethic. They are coming unstuck because of decision fatigue, the slow drop in decision quality that happens when people are asked to make too many complex calls, too often, for too long.

What’s in the report

Commonly cited estimates suggest the average adult makes tens of thousands of micro-decisions each day. For managers stuck between big-picture strategy and the day-to-day needs of their teams, that number climbs sharply, and the knock-on effect on the business can be serious.

Inside the report, you’ll find:

• A clear explanation of decision fatigue and the psychology behind it, including mental resource depletion and cognitive load
• The real impact on your business, from lost productivity and stalled processes to lower trust and growing retention issues
• Why current workplace pressures are putting middle managers under more strain than ever
• The Four Pillars of Structured Decision-Making, a practical model for sharing decision load, setting clearer guardrails, reducing decision creep, and improving communication
• What good results look like, including measurable outcomes from businesses already putting these ideas into practice
• Five actions your leadership team can start taking this week

The numbers paint a worrying picture. 71% of leaders now report increased stress from their roles, up from 63%. Trust in management has dropped from 46% to 29% in just two years. And fatigued workers are nearly twice as likely to experience reduced output compared to their peers.

The upside is that this can be fixed. Download the full report to see what is causing the problem, what it is costing your business, and what your leaders can do about it now.
