Adviser or Advisor in a job title?

[CowKeeper]

I am writing a job description for an HR adviser / advisor. Which is correct?

I have read that advisor is American English but can be used for job titles. I don't know which one to use!

I would use 'adviser'.

My gut feeling before I opened the thread was this would be about HR Adviser/Advisor.

It’s one of those English words where either spelling is perfectly fine. I prefer ‘advisor.’
I’ve been both for what it’s worth and always kept the spelling the previous employer adopted on my CV, so for some past jobs it says “Adviser,” and others, “Advisor.”

I’m a careers adviser and I would say adviser!

I used to be a customer services advisor...

Both are acceptable. I prefer "adviser".

I would use adviser.

Adviser is the more usual UK spelling.

In every HR Department I've worked in they are Advisor.

"Adviser" but I think it's a losing battle (see also: "fewer" and "less").

"Advisor" sets my teeth on edge. Its usage is probably too ingrained in British English now - used by too many ignorant people who probably don't know the difference between "licence" and "license" either.

Thank you for all the replies. It seems Adviser is the MN favourite and I agree. I really dislike American spellings creeping in.

Not to be unhelpful but a lot are moving to People Adviser now.

We have gone personnel, HR and now people. I wonder what we will be next!
