Just told my manager I applied for a new role in within my company. He took it as well as one could
He told me to keep him in the loop.
What was ironic was as soon as we begun our 1 on 1 he commented on the fact that I've been rocking a blazer for the past 3 weeks (my office's dress policy is business casual, only a suit/blazer if you have an important meeting or are meeting with a client). He said many people had asked him if I'm interviewing for a new position because I'd been rocking a blazer steady.
I countered that if I was interviewing I wouldn't be wearing the blazer every single day. Plus, it's cold in my office
