**What way is the best way to enforce the use of my full name?**

I can't write this without actually putting my real names in the title of this post, because it's very specific to my name usage, and as an over-40 woman in a workplace, where my new role will be a management position, it just feels like it needs to start being more formal - for me personally in my career environment.

Maddie is the name I've gone by for the first half of my life, up to about 35 years of age. It didn't matter too much if people used that at work or in social contexts. However, I've gradually been phasing out of that in the workplace to my full name which is Madeleine.

Being that I have progressed in my career to a position where my shortened version is more personal, used by family and friends, but in a professional environment, I feel my full name is just more 'professional' and Maddie is too familiar; when people start shortening it, I feel like a cow for correcting them.

I'm starting to roll my eyes a lot when people use my shortened name, as if it's now starting to grate on my nerves and I don't want to snap at someone for using it because, essentially, this is a personal annoyance - not their fault.

*Edit:* Note I'm starting a new job, meaning I'll be with new people - nobody I know from any previous interaction. Fresh start, so just working on how to move forward with the name I'd prefer to be addressed by.
