Are you an Microsoft Exchange or Office 365 shop?
If I had a work phone it would most likely be an iPhone. Since I dabble in Android enough I would just have them give me an iPhone for work to see how the other side lives.
Broke down and asked for a work phone because I didn't want company to have security controls on my phone and without doing so work email bites because we can't use a standard client.
Ugh.... Iphone 6S.....how boring.....eventually it will be a 7....still boring.
What are you using for work?
