Advice regarding internal promotion

Last week, I was browsing the CalCareers website and came across an internal promotion opportunity at a different department. I had some free time, so I decided to apply.

I was fortunate to receive a call for an interview, and I accepted it. Now, I’m unsure about what the proper process is.

I haven’t told my current manager that I applied or that I’ve been invited to an interview.

I need to provide references—should I include my current manager or someone from my team?

I know my manager and team would speak well of me, but I’m concerned that asking for a reference might upset my manager. If I don’t get the job, I also don’t want to create tension or damage the good working relationship we have.

I like my current role, my team, and my manager.

What do you recommend I do?
