Some "skilled work" intersects with "hard work". There's a ton of work in the construction industry that requires a very high level of specialized knowledge that sometimes takes years of college and practice in their industry to learn, just for example. Even more reason that it's strange that some people find one type of work somehow inherently superior to the other in generalized terms. I tend to think that the skill and care that one puts behind their craft is maybe what should be more important.
