The problem starts with the name, humans are not resources. Stones. metals and food are resources. It's a slave term to see people as resources. I will never contract myself to those companies and people.
1a : a source of supply or support : an available means —usually used in plural
1b : a natural source of wealth or revenue —often used in plural
1c : a natural feature or phenomenon that enhances the quality of human life
1d : computable wealth —usually used in plural
1e : a source of information or expertise
2 : something to which one has recourse in difficulty : EXPEDIENT
3 : a possibility of relief or recovery
4 : a means of spending one's leisure time
5 : an ability to meet and handle a situation : RESOURCEFULNESS
I'd say humans are resources under definitions 1a, 1e and 2. Those things aren't particular to slaves.I personally find this a very comfortable arrangement. I am a merchant of my own labour. I can upgrade the value of my labour by adding skills (in the same way that a merchant of stone could get a better price by reducing defects). I can seek a better price. I am free to terminate the arrangement when it suits me.
And another thing, you are not free to terminate the arrangement because you need money to live, the company is indeed free to terminate it.
Edit: I notice this person's account posted once 32 days ago, then 44 days ago, then 51 days ago ... I don't expect a response anymore.
I read that as them saying they'll never work for a company that treats people as 'resources'.
