I've yet to find many organisations that split those responsibilities up enough. This might work for 1% of orgs, wait no - 1% of tech orgs, but everyone else needs something better.

I can't vouch for your experience but as a sysadmin myself I've found 100% of the companies I've worked for has had dedicated sysadmins ;)

I'm being a little flippant here though, I am aware that developers are often asked to wear the sysadmin hat too.
