I've been at my job for 3 years and recently raised to my manager that I do more than is in my JD and would like my salary to be reviewed. They agreed and also said they would like to change some aspects of my JD. I was then informed that because my JD and salary are changing I will need to re-interview for my job and it will be externally advertised too.
I have a job interview for another job of much higher pay for similar work, I'm in the mindset now of fuck my current job and put all my time outside of work towards preparing for this other interview.
Any advice or thoughts on this??
I'm so annoyed and humiliated that I'll possibly lose my current job to a better candidate
