Is it normal to regret a new job?
Mostly.Normal for most people
Yes, it’s normal to have doubts or regret after starting a new job. A big change can feel uncomfortable before you’ve settled in, though ongoing problems may mean the job isn’t a good fit.
Starting a new job can bring a weird mix of excitement and “What have I done?” You’re learning new routines, meeting new people, and comparing the reality with what you expected. Lots of people have a wobbly adjustment period, even when the job is ultimately right for them.
Give yourself a little time to see whether the discomfort eases as you get your bearings. But if the role is very different from what you were promised, or the problems keep affecting your well-being, it’s fair to take that regret seriously and think through your options.
