I am imaging some kind of "self test" occurring during launch, and after in the air, before responding to commands, where all instruments are checked for reasonable measurement, and some type of physics test is done near the ground and the air, to confirm the drone is not carrying anything (Such as drugs, weapons, hazardous devices, or other stowaways, such as extra electronics mounted to it), And failure of a test forces limited movement and gradual automatic descent.
And I imagine anyone with nefarious intent (or anyone who doesn't want to deal with that BS) will just build a quad-copter from easily sourced components and a programmable flight controller.

The labor rules "employers" are subject to, make employee choice next to impossible to allow. You cannot as an employer allow someone to work 10 hours one week then 45 the next if you are obligated to provide them with health insurance, and sick pay.
Where in the US are employers required to provide sick pay or health insurance, other than federal contractors? And sick leave for workers with flexible hours is simple. You accrue a set fraction of a hour for each hour worked. A similar compensation could be worked out for health insurance as well.
Admittedly, the salary range for both of these professions is wide, but on average a general practitioner makes double what a plumbers does.
