My manager is pushing me to take over her position, but it's not my career path

I've been in my job for 6+ months now but my manager is already laying into me to take over her job title of Registered Care Manager.
I am flattered to be offered this training opportunity and for her to think I have great potential, however I feel that at this stage I don't feel ready for this commitment due to lack of practical care experience.

I mainly work in Recruitment Administration side of her business which is why I feel thats where I belong - not a Registered Care Manager.

In my supervision, I did state exactly that but I don't think she's got the message...

Also a different company is offering me what I want, but I don't have experience in payroll which is the main side of the role.

I'm not sure what to do, does anyone have any advice?

Why is the other company offering you a job, when you don't have experience in payroll? Have you been for an interview, or have you been head hunted? There are always jobs going in payroll, with too few people to fill them. Therefore if you accept this other job, even if you don't like it, you will be snatched up pretty quickly by other companies with your new found experience in payroll. Plus the rest of the role is exactly what you have been looking for.

Will they train you in payroll? Will you be trained by the previous person before they leave? It’s a well established company too.

Sounds like a good position. And is the pay a step up? Do they seem like nice people? You may have the opportunity to visit the workplace for the second interview then you can get a clearer picture

They said the payroll side is quite basic and they are willing to train me. I've also told them my experience in the care field as I know the regulations a provider should work towards to. In my current job I've already been trained in preparing for an inspection.
So I do know what to expect in the job.

The only problem is payroll for me because I don't have to deal with it in my current role. I've worked in recruitment since university 5 years ago and have never dealt with the payroll side.

When I spoke to the Finance Manager who phone screened me, he complimented on my experience and I told him that I want to stay in HR Recruitment as I feel that is my main area of expertise - which he appreciated and said positively that I have potential to step up the career ladder within the company.

My manager has the same vision about me though - but in the care field as a Registered Manager, so I'm
slightly confused as to which path I should take?

Inthe short to medium term, registered manager is a stronger role than the HR route. There are a limited number of registered manager, there are endless potential HR managers.

You might want to stop telling people what you can't do, when the offer you career advancement as well! If you don't have confidence in yourself at least try and develop some confidence in what other career professionals are telling you! You are obviously being spotted for the right reasons, just accept that and take onboard the advice. No-one is fully ready for a new job when they get it, there's always an amount of learning to do.
