Like most of us, I have a personal LinkedIn profile, which I keep as updated as feasible. Sometimes managers send me a message asking for my resume. Now, since I am already employed and busy on a project, I politely decline and let them know that I am not open for opportunities at the moment but might be in the future.
My actual manager doesn't know about these messages and this has gotten me thinking.
On one side, I'm not seriously considering any of them. I welcome them because these connections might become useful in the future, but at the moment I'm not unhappy with my current position and salary so I have no reason to change.
On the other side, I am worried my manager starts taking me as granted and I do not grow as I could, both in position and salary. I have heard complaints about my company not giving promotions with the same policy other companies I can easily access do. Making it known that I have offers could have them take more care of me, leading me to speed up my growth. Yes, it could backfire, and that is something I want to seriously avoid.
Is it something I should do? Should my manager be aware of me being offered opportunities to other companies? If yes, how to make this happens such that it doesn't look like I'm "blackmailing" a raise?
Just to be clear, as I said I'm not unhappy right now and if I ever start to become unhappy I'll be sure to have my manager know first-hand. I'm not asking on how to ask for a raise, I'm asking if I can do something to make my manager act to keep me happy, before me getting unhappy. Since I'm not that much experienced, any relevant experience is more than welcome, even if only slightly correlated.
I wanted to add a few points to clarify some things that have come up in comments and answers and that are slightly out of scope:
I know they are not "offers", I have just made a poor word choice. As one comment suggested, read "approach" whenever I said offer or proposal. That is what I really meant.
I know they are mostly not that serious and not exclusive to me
