Identifying burnout early is now a business-critical skill, not a “nice to have” wellbeing perk. When warning signs are missed, the next communication from a valued employee may be a resignation letter.

What burnout looks like before the resignation

Burnout builds gradually, so the key is spotting small but persistent shifts rather than waiting for a crisis.

Typical early indicators include:

• Noticeable drop in enthusiasm for work the employee used to enjoy.
• Increasing cynicism, irritability or “edge” in emails, calls and meetings.
• Rising error rates, missed details or quality issues, especially from high performers.
• More frequent sickness absence, late starts, or working very long hours to “keep up”.
• Withdrawal from optional activities (socials, projects, mentoring) and cameras off in virtual meetings.
• Comments like “I’m exhausted”, “I’m drowning”, “I just can’t catch up” that get laughed off rather than explored.

A practical example: One small travel tour company noticed, through regular staff surveys, rising stress and disengagement long before people started quitting, which prompted a targeted response.

When burnout becomes a resignation letter

By the time someone resigns, you are often seeing the end of a long, invisible process where earlier signals were minimised or ignored.

Recent public stories show common patterns:

• An experienced software professional, Bhupendra Vishwakarma, resigned citing excessive workload, unrealistic expectations and lack of appreciation; his case resonated widely because many felt similarly stretched and undervalued.
• In another widely shared case, an employee left without another job lined up after months of unmanageable workload and understaffing; when he resigned to protect his mental health, management reportedly labelled him “selfish” instead of addressing systemic issues.

These examples reflect a broader trend where organisations treat departures as individual failures rather than evidence of chronic workload, culture and leadership problems.

Companies that struggled to deal with burnout

Not all organisations handle burnout well at first; some become cautionary tales that others can learn from.

Common missteps include:

• Focusing on resilience training and “self-care” while leaving workloads, staffing and targets untouched.
• Rewarding overwork (late nights, constant availability) and quietly penalising boundary-setting.
• Treating each resignation as a one-off issue, rather than tracking patterns in exit interviews, surveys and performance data.
• Responding defensively when employees raise mental health or workload concerns, as in the example where management criticised an employee who refused extra work whilst on notice. ​

Commentary from workplace mental health experts notes that many organisations have long hidden burnout behind labels such as “poor fit”, “performance issues” or “career transition”, only recognising the pattern once attrition and sick leave become too expensive to ignore.

Companies that tackled burnout successfully

Some employers have started to address burnout proactively, treating it as a design flaw in the way work is structured, not a personal weakness.

Examples and lessons include:

• A small travel tour company in Florida introduced monthly “pause days” (no meetings, flexible hours, option to work from home) after staff surveys showed rising stress. Within three months, reported burnout symptoms dropped by 23% and managers noted stronger morale and improved productivity over the following year.
• Practitioners who have implemented structured burnout-prevention programmes report measurable business benefits such as reduced absenteeism, lower voluntary turnover and higher productivity when they combine leadership alignment, clear role expectations, and ongoing measurement. ​

What these organisations have in common is that they listen systematically (through surveys and data), train managers to recognise burnout, experiment with ways of working, and then track impact rather than relying on ad hoc wellbeing gestures.

How HR and leaders can spot burnout before it’s too late

To catch burnout before it becomes a resignation letter, organisations need deliberate practices rather than informal “open-door” promises.

Practical steps include:

• Measure the temperature regularly: Use short, frequent pulse surveys on workload, autonomy, recognition and manager support; watch for upward trends in stress, not just extreme scores.
• Track leading indicators: Combine survey data with patterns in overtime, annual leave not taken, sickness, error rates and near-misses; high performers showing sudden dips deserve particular attention.
• Equip managers: Provide concise training on recognising signs of burnout, having psychologically safe conversations, and adjusting workload or priorities rather than simply offering platitudes.
• Redesign work, not just wellbeing benefits: Review staffing levels, meeting load, expectations around availability, and the number of priorities each role is expected to juggle.
• Create early, low-stigma interventions: Offer options such as temporary workload rebalancing, project swaps, “pause days”, flexible arrangements, or short rest periods before someone reaches a crisis point.
• Close the loop: When you hear about stress or see worrying trends, act and then tell people what has changed; silence after feedback accelerates disengagement.

An illustration: imagine a high-performing account manager who starts missing minor details, becomes unusually abrupt in emails, and stops joining team coffees; this is the moment for a structured wellbeing conversation and workload review, not another stretch target.

Handled well, burnout can become a signal to improve how work is organised rather than the prelude to a resignation letter – protecting both your people and your organisation’s long-term performance.
