"I wish I hadn't changed jobs." "I want to go back to my old company." — Have you ever felt this way after a career change? According to Shikigaku's survey, about 60% of job changers report feeling regret, and MHLW data shows approximately 11.4% are dissatisfied with their new employer while 21% want to change jobs again. Career change regret is far from uncommon.
This article ranks the most common reasons for career change regret, provides specific coping strategies for each, and offers five criteria to help you decide whether to stick it out or make another move.
Multiple surveys paint a consistent picture. MHLW data shows 11.4% dissatisfaction and 21% wanting to change again. Shikigaku found 59.7% experienced regret. Tenshoku Kaigi's survey of 1,034 people found one in four regretting their move. The numbers vary by methodology, but the reality is clear: a significant number of people experience some form of post-change regret.
The most common regret involves gaps between expected and actual compensation. Since salary dissatisfaction is also the top reason people change jobs in the first place, the expectations are high — and the disappointment is proportionally deep when reality doesn't match.
Discovering that actual duties differ from what was described in interviews or job listings is a major source of regret. This directly impacts daily motivation and can be deeply demoralizing.
Difficult relationships with supervisors and colleagues are extremely common regrets. Since interpersonal dynamics are nearly impossible to assess before joining, this is an area where gaps between expectations and reality are most likely to occur.
Cultural mismatch — discovering the company's actual atmosphere differs from what you were told — is another top regret. Company culture is rarely documented in job listings and difficult to sense in short interviews.
Finding that growth opportunities are fewer than expected is a regret that's hard to identify before joining, as career paths within a company are often opaque from the outside.
Longer hours, unexpected weekend work, or broken promises about remote work options round out the top six. With work-life balance rising rapidly as a career change priority, this source of regret is becoming increasingly common.
Use these five criteria to guide your decision: (1) Your dissatisfaction persists after 3+ months — initial adjustment stress usually fades, but persistent issues signal a real problem. (2) The root cause is something you cannot change — distinguish between fixable issues (your own skill gaps) and unfixable ones (company culture, management philosophy). (3) Your physical or mental health is being affected — don't sacrifice your wellbeing waiting for things to improve. (4) Actual conditions clearly differ from what was promised — significant gaps between your offer letter and reality are the company's problem. (5) You can clearly analyze why the first change failed — without this understanding, you risk repeating the same pattern.
Looking at the regret rankings, most causes trace back to insufficient information before joining. Salary, job content, relationships, culture — none of these can be fully understood from job postings and interviews alone. This is why experiencing the actual workplace before committing is the most effective way to prevent regret.
Otameshi Tenshoku lets you try working at a company as a side job without leaving your current position, experiencing the culture, work dynamics, and real duties firsthand. Temp-to-perm staffing, trial onboarding, and Trial Employment are other options. By adding experience-based approaches to your toolkit alongside traditional resumes and interviews, you dramatically reduce the risk of post-hire regret.
Career change regret concentrates around six core areas, all rooted in pre-hire information gaps. If you're already experiencing regret, assess the three-month adaptation period, classify your issues, and consider whether internal improvement is possible. If not, a second change may be warranted — provided you've thoroughly analyzed your first experience. And for your next move, leverage workplace experience services like Otameshi Tenshoku to confirm compatibility before committing. Let your "never again" feeling fuel a smarter next step.
