Burnout does not arrive as a dramatic collapse. It creeps - the Sunday dread that starts on Saturday afternoon, the small tasks that suddenly feel enormous, the cynicism about work you used to care about. By the time most people admit something is wrong, they have been running on empty for months, telling themselves it will ease once this one project ships. It rarely does, because the project is not the problem; the pace is.
Catch the early signs
The World Health Organisation classifies burnout as an occupational phenomenon, with three markers worth knowing: exhaustion that sleep does not fix, growing mental distance or cynicism about your job, and a drop in how effective you feel. Watch for the physical tells too - disrupted sleep, frequent headaches, catching every cold going round because your immune system is depleted. The earlier you notice, the cheaper the recovery, and the people who crash hardest are usually the ones who ignored a year of warnings because admitting they were struggling felt like weakness. It is not weakness. It is a workload that no amount of personal resilience can absorb indefinitely.
Have the workload conversation
You cannot boundary your way out of a job designed for two people, so at some point the conversation has to move from your evenings to your manager's desk. Go in with specifics rather than a general plea - "I'm carrying these six priorities, here's what realistically gets done well by Friday, which two should I drop or push?" That reframes it as a prioritisation decision they own, not a complaint about your stamina. Protect your actual time off as well; take your full annual leave, and switch off properly when you do, because a holiday spent checking email is not rest.
- Block recovery time and defend it like a meeting with the chief executive.
- Learn to say "not this week" - a sentence that gets easier each time you use it.
- If you are signed off sick with stress, that is medical leave you are entitled to, not a black mark.
Your employer has a duty here
Under UK health and safety law, employers have a duty of care that includes managing the risk of work-related stress, and the Health and Safety Executive publishes management standards on exactly this. If raising it changes nothing, that tells you something important about whether the job is survivable as designed. Recovery is real, but it starts with treating rest as a requirement rather than a reward you have to earn.
