true. why does that make it a bad definition? it is a material relationship, it is okay to call it accurately.

I'm not a native speaker, but to me exploitation has a negative moral connotation. I think it's possible for companies to make use of their employees to make a profit without exploiting them.

the negative moral connotation of "exploitation" is an effect of anticapitalist propaganda :)
