(UK) Promotion choice

So im included in an email from BM offering to become an area leader or shift leader(if I was to do it I’d rather be area leader). I’m 50-50 about it and I don’t know whether it’ll be worth it for me or not. I’m currently a frequent closer for the store which I do enjoy as it’s quite fun and chill. I have reasons to go for it and not to. I am completely unsure on what to do so I was hoping I could talk to people about it and see what it’s like I’ve spoken to a few people at my store about it but I’m still unsure.
