What employee rust-out is and how to prevent it

Executive overview

Burnout gets attention, but rust-out — boredom and disengagement from under-stimulation — is equally damaging to retention. Employees whose skills go unchallenged feel listless and apathetic, and quietly start looking elsewhere.

Catching rust-out early, before it becomes disengagement, turns a retention risk into a development opportunity.

The best time to act is before the employee feels bored — not after they hand in notice.

How to identify rust-out (and pre-rust-out)

• Rust-out stems from lack of challenge, not overwork — the opposite of burnout
• Shared indicators: low drive, increased frustration, late arrivals, early departures
• Pre-rust-out signs are more positive: asking for learning opportunities, raising career progression in 1:1s, seeking feedback, connecting across the org
• These pre-rust-out behaviours signal a good employee who wants more — respond proactively

Strategies to prevent rust-out

• Upskilling: continuing education, in-house training, or certifications redirect energy productively and improve retention and satisfaction
• Career pathing: work with employees to map potential future roles aligned to their goals and the organisation's needs — gives them a goal and a focus
• Levels documents: define the skills and scope needed to advance; adds pay transparency and acts as an equity lever
• Regular 1:1s and skip-levels: gauge satisfaction, set expectations, ensure managers are distributing workloads and providing feedback consistently
