All you need is a small distraction like someone saying something to you and
you can loose your hand when machine starts and you are not ready changing
parts.

Lots of non-CNC machines run automatic cycles being hand feed. CNC's
are no different, you just have to be aware of the machines position,
give plenty of time to load/unload safely without rushing. If an
operator is late loading hit feed hold button or skip the cycle all
together.

I have programmed, set up and operated machines where one part is
running on one side of the table and on the other side a completed
part is being unloaded and a new blank loaded. Very little machine
idle time. It is limited in its application for obvious reasons but
for the right job it works well.

At end of each tool and/or program after block containing M05 add
/M09; /M00;. If operator goes on break or needs some extra time but
doesn't need to stop in the middle of a cycle simply turn block skip
switch to off. So at end of tool/program spindle stops, coolant turns
off & program stops.
