I don't want to have anything personal on a device someone else has full control over.
I don't want any work-related notifications after I clock out. If I'm being paid to work 8h/day, company has my attention for 8h/day. Overtimes can be arranged, but doing so on my own will and not being paid for it will never happen.
I don't want to be held liable for leaking company secrets in case I lose my personal device.

At some point we all have to realise that anything we posess electronically is only a copy of the version the three letter guys have in our files.
If the choice is between sharing my data with a three letter agency thousands of kilometres away and sharing my data with a three letter agency and my employer, you're damn right I'm choosing the former.
I even refused an otherwise sensible request from my former employer to install WhatsApp on my phone because I was not interested in using it personally, and they were not interested in providing me a work phone for it.
