Accepted New Job but seen another role which is of interest??

[Lightsareonnobodyshome]

Have recently accepted a new job but have seen another similar role advertised which I find really appealing, I have contacted the recruiter and they have asked me to forward some further details so they can take my application forward. The employers are linked, wouldn't be same line manager and this would be a new role, but just not sure what to do?
I still have my notice to work but just feel a bit unsure as to what to do, not sure if it is nerves or just overthinking..

You are mucking the employer about having accepted the offer, because they’ll have potentially informed other candidates they were unsuccessful. To be fair if you don’t want the role let them know
Of course you need to chose the job you actually want and if that means letting someone down that’s unavoidable

This is business, not personal. You're replaceable, it's likely they will be able to go back to the unsuccessful candidates if any of them passed the threshold for the role, if not, they can re-recruit. A mild inconvenience for a hiring manager does not surpass your need/desire to pick the right job. I say that as a hiring manager who has had job offers turned down last minute and turned down roles after verbal accepting (for various reasons).

chose the job you actually want but let the original employer know quickly so they can recruit again
Sometimes it’s how timing works. Wait for right job, two come at once.

@userchange987 yes the employer can recruit again,but it is still inconvenient esp in areas where there are skills shortages and potentially post remain vacant if the other candidates get alternative offers and become unavailable

Of course it’s not the op problem

As a professional courtesy tell them quickly if other job you’re applying for makes you an offer

@EspressoDoubleShot an inconvenience they are getting paid for as a part of their job vs the OP's life, the two are not comparable. Of course OP needs to tell them as soon as she is able but it would not make sense to do so before another job is secured. OP needs to be as professional as possible but protect herself, the job will be filled, it isn't the end of the world. I don't know why people think professional courtesy is more important than protecting yourself, as I say I'm a hiring manager and I'd never resent anyone for turning down a job even if it was the day they were due to start (so long as polite about it of course) that's just life, as I say, it's business not personal.

I’m not sure what point you’re labouring I think op needs to take job she wants
I’ve experienced candidates withdrawing from posts and it is irksome. It impacts upon staffing, skills mix etc.The result was we had to recruit a locum. Higher cost and transient. There is an inevitable impact to withdrawal from a post, it is an inconvenience. It means other staff have to increase their workload and work remain outstanding . It isn’t as simple oh well it’s business . There is an impact to withdrawing to a job offer. On balance op needs to suit herself but the decision does impact it is disruptive unless there an immediate other candidate who will step in

I just don't think it's worth trying to guilt trip the OP about the inconvenience she's going to cause, so what? It doesn't change the fact she needs to do what's best for her and the hiring manager will have to crack on no matter how "irksome" it may be. I'm sure she's all too aware of the inconvenience it may cause others hence her posting on here, but I don't think she needs to people please. Be honest, act with integrity, and it'll pan out. She doesn't owe anyone anything. You're paid to do a job, sometime the job goes to plan, sometimes you're met with inconveniences, so long as you're getting paid I don't know why you're continuing to "labour the point" that she's being inconvenient.

Read and re-read my posts. Twice I said chose the job you actually want

I am on no way guilt tripping the op, why would I? But let’s be clear it’s an action that has an impact , it is a potential inconvenience

You’ve said in your field it is mild inconvenience
In my field it is significantly more than mildly inconvenient to withdraw from a post, however it happens
