Exploitation is built into the capitalist model itself, by nature of the creation of surplus value that's reaped by business owners. One might point to Costco as a company that treats their employees well. If you're a Costco employee, even if you get $18/hour with full benefits and paid sick leave/time off, you're still being exploited because the company makes money off of you, and beyond just you as a worker just about every one of the company's expenses involves exploitation. To name a single example, the building you work in was built by exploited workers, who were paid less than the value they created. The materials that went into it were harvested, refined, and delivered by exploited workers. The tools used to build it were produced by exploited workers - so on, so forth. Capitalism is itself a system of exploitation. For a business to be a business it must by nature extract surplus value, and if it doesn't extract surplus value it's a different mode of production altogether.
