Keep it civil? Nobody said anything about "less human". That's a vile straw man.
I suppose it depends on the eye of the beholder. Humans aren't disposable.
It's not a straw man. It's in there in the original comment.
There is nothing about that that implies you're not treated with dignity.
Contractors are treated with less dignity than they deserve on a number of fronts
As a contractor and even as an employee I've been treated with less dignity than I deserve especially when being let go on a moment's notice and treated like a plague carrier the minute I'm terminated
Being treated as "extra disposable and second class" is being treated as less human than a FTE. It's up in the air whether that also means they were being treated as "less than human."
You seem like you may have been burned in the past and I think setting clear expectations up front can help. We used to tell our contracting candidates "The full-time staff will judge you differently than they judge one of their own so be prepared to dress better, work harder and be recognized for it less." But lots of people already understood that and there were plenty that really preferred the flexibility and variety of contracts and felt bored and trapped as FTE. People can have different life priorities than we do.
I think my agency was one of the good ones, but it was still rare that I was offering someone a clear career boost instead of a placeholder or a way to pay the bills. But bills need paying too. We used to be explicit about that and tell our contractors to keep looking for full-time work and treat the contract as a gap-fill and that we would cheer them on and gladly serve as a reference if they found better work. Our idea was that contractors who find dream jobs turn into eventual hiring managers who remember that we were honest.
And I see a vibrant discussion of language and rhetorics below:) I do want to clarify that I meant the position is disposable and that you are a second class citizen in the context of the first class FTEs. If anything in this situation feels dehumanizing it's due to the modern corporate philosophy of labor as resource. I'm out of recruiting now and my mental health and perception of self-worth are much improved for the change.
At least in my part of the country, Contract workers are paid a premium over FTEs because of that risk. Broadly speaking the more 'secure' the contract job (i.e. years vs months) the less this differential in pay is, but I know plenty of people who specifically do contract work knowing that risk but finding the payoff worth it.
But they certainly don't go out of their way to help contractors or each other unless it's to complain about the company at least that is all I've ever witnessed
