I started in my current job 6 years ago. First as software developer then I changed to part time system administrator and time later I became FTE system administrator. In total, as of lately, I spent 3 and a half years in system administration duties and now I'm exhausted as it's been mostly help desk so I want to be back as software developer again and then I can continue my 11 year professional IT career in that area.
I talked with the boss of the software development area on the potential move and he gladly told me he would like to have me in his team (besides other 2 very senior colleagues also can back up my potential move).
I have one junior help desk guy under me, so I'm somewhat covered on training my potential replacement like real quick.
My question is how should I approach this proposal of lateral change with my boss?
I'm thinking on this approach so let me know what you think:
Hi Mrs Boss:
. I want/need to change my career back to software development but I still would like to be working for this company otherwise I will quit.
. The supervisor of the software development team agrees that he would like to have me as sw developer in his team.
. This is the status of my current job.
. This is a potential schedule/timeline of 8 weeks for the transition if you agree.
. The guy I have under me can make a gradual transition to my current duties following this plan.
I have an offer from an external company to work for 10% less salary but at least is in a software development leading role, so that is my alternative in case things go south, but I would like guidance from more experienced negotiators as I don't want to screw the relation with my boss.
