I'm kind of a strange situation and I'd like some advice on how to navigate forward. Here's the details.
My primary skill and career has been in IT. I currently work in a related role for a company whose primary business is not IT. The amount of work I have is variable and sometimes it is quite quiet.
I have a secondary professional skill, practiced via freelancing, related to marketing, which is the primary business of my employer.
My employer is about to undergo a restructuring. This is being made light of, but I'm wary: it's possible in the medium term I may be relocated, see undesirable changes to my job or even lose it.
The marketing department where I work know about my secondary skill and, occasionally, call on me to use it. My actual line manager isn't really aware of this: I normally pick it up during the quiet times. I have been told by marketing it is likely they will want more of my time for this in future. However they already have the necessary skills in their department - I'm just helping out to save them time (plus I'm pretty good at it).
So here's the deal: I would like to try and get an official split in my job time between IT and marketing. That way I get some cool extra stuff for my CV and - as I see it - I put myself in a better position to negotiate or otherwise protect myself during a restructuring.
I don't really want anyone to know that my IT work is sometimes quiet as that leaves me in a more vulnerable position. I also don't particularly want to expose myself as wanting to do this to my line manager in case it sounds like I'm a flight risk.
How should I best approach negotiating this? Or am I best off staying quite for now until the restructure is complete?
