I am currently on maternity leave and my company is in the process of hiring a replacement for me. However, a friend of mine applied and was asked to go for an interview. She turned down because in the end she didn't think a maternity replacement job was a good fit. She was told by HR that there is another fulltime position and asked if she would be interested.
My question is: how can I ask the HR person about this position? As I wouldn't want to miss an opportunity to apply for an internal job which they may not be posted (did happen in the past to someone else on maternity leave). Especially, since my friend was told it is an additional position to mine but in the same area. A lateral transfer to this position might appeal more to me now that I have kids.
I am worried that by asking I would seem like I am not happy with my job.
