I'm issued a mobile phone by my employer. Today I don't have any option to "carve out" a niche for my personal activity on my phone. AFAIK they can know anything and everything. Google Play for Work sounds like it would help out here.
I was issued a work phone too. I decided it was much more worth it to carry around two phones, with my work phone in my bag for the .01% of the time they actually needed to get in touch with me. Work only needs to know my work number, they shouldn't, nor needn't, care what I do on the 80+% of the time I'm not on their clock.
