A job is a job. Your just a number, no business cares about you. You cost them money and as soon as your out the door your forgotten. Even if you create some super script that powers that business. On rare occasions where you do you make outside work friendships the chances are high that you'll end up leaving them or they'll leave you.

Whenever you start to question your job, start looking to jump. The energy of "I am dedicated to my role because the company treats me well" is an pathological lie and psychological demoralizing. The more you cater to this the more you're giving them control over you.

It may seem cushy, it may be cosy and you could be okay with that but at any point they can and will throw your role away. Plus at that stage if you ever want to progress, further progression becomes finite. Don't fall in to that trap.

They want you with your skill set because training someone up, you, to that of a higher level costs resources. Either that or they then lump someone junior that you have to manage. So now your working two jobs destroying the coziness you once had. What was the first reason for this job in the first place? Money? Skills? Friends?

It's always money and that's why we work. Anything else positive is just an added bonus. So yes, quit your job if you're turning unhappy.

Interview while your employed, and don't be afraid. Employers prefer you jumping ships when your employed. It's the way forward in getting higher wage, new skills plus a new better you. You can use your current employment as bargaining chip or vice versa. On the former you'll find they're be happy to kick you out as soon as it's mentioned.

A interviewer is more interested in the skills you bring than why you're leaving your current job. The interviewer is human too, well for now anyway.

>ChatGPT told me I should quit my job

That could be pretty convincing.

OTOH, sometimes if the job is halfway decent you're really better off than most, so the right move could be to keep the job and break up your engagement with the bot.

So you can look for greener pastures in either regard.

How about whichever comes first?
