Recent years have seen a flurry of expensive lawsuits over the difference between a contractor and employee, most recently at Uber, so my views on that are likely outdated. I shouldn't be surprised that employers these days err on the side of caution and reclassified many traditionally contractor jobs as employee jobs.
Salaried jobs I've had all expected me to work 40 hrs. I'd moonlight on my own business, but was always careful to get a signed agreement in advance from my employer allowing me to do so. Some people moonlight and then live in terror of their employer finding out and claiming ownership over the moonlight business, but getting the agreement in advance forestalls that problem.
You're misunderstanding me again. I do the job of an employee. I simply have never had any expectation of "40 hours," or any other fixed amount of hours placed upon me as a salaried tech employee.
