Most people recognise the dread of a Sunday evening. If that feeling of anxiety has become a weekly ritual, it might be more than just a bad week. But what if that feeling isn
isn’t just a fleeting moment but a repeating pattern, then it’s time to pay attention. Quitting a job isn’t a failure - it’s a difficult, mature decision about your future. The key is knowing whether you’re just in a temporary slump or facing a genuine dead end.
So how do you tell the difference? Below are nine honest signs that it might be time to start planning your exit. These aren’t about a bad day or an annoying project; they are about fundamental mismatches between you, the role, and the company. If several of these feel deeply familiar, it’s a [signal that your career needs a new direction](/blog/how-to-know-if-youre-in-the-wrong-career-in-your-20s "7 signs you might be in the wrong career path").
Your Body is Sending You Distress Signals
Forget the cliché of ‘work stress’. We’re talking about real, physical symptoms. Are you getting persistent headaches only on workdays? Is your stomach in knots every Sunday night? Perhaps you’re suffering from insomnia, grinding your teeth at night, or catching every cold that goes around because your immune system is run down.
These aren’t just minor inconveniences. They are data points. Your body often knows you’re in the wrong place before your brain is ready to admit it. When your job starts to manifest as physical illness, it’s a serious red flag that the stress is moving from manageable to toxic. Don’t ignore it - your long-term health is more valuable than any job.
You’ve Stopped Learning or Growing
Comfort is a trap. Early in a job, the learning curve is steep and exciting. But if the past year has been a flat line where you’ve not acquired a single new skill, taken on a meaningful challenge, or felt stretched in any way, you’re not in a job - you’re in a holding pattern.
A good role should develop you. If your manager deflects every request for training, if there are no opportunities to take on new responsibilities, and if you can do your entire job on autopilot, you are [stagnating.

Your future self needs you to prioritise growth over comfortable familiarity.
The Culture Makes You Cringe
Do you find yourself rolling your eyes in meetings? Do the company’s values, proudly displayed on the wall, feel like a joke compared to the day-to-day reality? A toxic or misaligned culture is a slow-acting poison that erodes your motivation and sense of self.
Maybe it’s a culture of gossip and backstabbing. Maybe it’s a relentless ‘hustle’ culture that celebrates burnout. Or perhaps it’s just a place where nobody seems to care about the quality of their work. If you feel like an outsider, dread team-building events, and have to put on a different personality to fit in, you’re expending valuable energy just to exist, let alone thrive.
Do the Maths: Can You Afford to Leave?
Before you write a dramatic resignation email, open a spreadsheet. [Quitting a job without a financial safety net](/blog/stuck-in-a-job-you-hate-at-30-a-calm-plan-to-get-out "A calm plan to exit a job you hate responsibly") is a privilege few people have. Figure out what your ‘freedom fund’ number is - the minimum amount you need in the bank to survive while you look for your next role.
Start by listing your essential monthly outgoings: rent or mortgage, council tax, utilities, food, and crucial travel costs. Don’t include discretionary spending like takeaways or subscriptions - this is about survival. A common rule of thumb is to have 3-6 months of these essential expenses saved. If your core monthly costs are £1,800, your target is between £5,400 and £10,800. Seeing that number makes the goal concrete, not just a vague wish.
Once you’ve got your number, [check your current employment contract](/blog/how-long-should-you-stay-in-your-first-job-before-moving-on "Navigating job changes and employment durations"). What is your notice period? For a senior role, it could be three months or even longer, giving you time to search while still being paid. Also, check if you have to repay any training costs if you leave within a certain period. Knowing these details prevents costly surprises down the line.
