Ok so I'm applying for a new job (within the nhs, but different trust)
The job I'm doing at the moment is quite niche so I have to put my current manager as my reference (I'm pretty certain it will be a good reference).
At what point do you let your current manager/ask your current manager know that you have out their name down as a reference?
Out of politeness is it when (if) I find out I have an interview? Or afterwards (if) I'm offered the job? (I ticked the do not contact pre interview box)
Although I'm pretty certain it would be a good reference I know she'll be upset I'm leaving or even thinking or leaving.
But then if I only tell her after (if) I'm offered the job she will know I put her name down without asking.
A few reasons for wanting to leave- pushed into moving into a higher band so taking on more work within the same hours, a lot of pressure on me to increase my hours, new job would be closer so less of a commute and WFH is ending in my current job 
Probably overthinking but it's stressing me out! Thoughts?
