Little pedantic translation thing:
I think you just meant "White company" not "white-collar company". They refer to different things (A white company is one that's nice and supportive and isn't uncaring about how hard it works its staff to meet goals or that attempts to avoid having management that are abusive or manipulative of the workers as opposed to the stereotypical "black" company that's a slave-driving hellscape that grinds its employees to paste for the sake of their corporate betters. A 'white-collar' company refers to basically any job in an office setting where the employees largely perform business functions that don't require manual labor. Like producing reports, holding meetings with clients, planning strategies, or managing finance or resources. Its opposite is a blue-collar job, which usually means manual labor or trades (or occasionally there's also 'pink-collar' that refers to the service industry and jobs that were historically dominated by women like cashiers, baristas, flight attendants, retail clerks, etc))
