It's a sign of how much power porky has over workers. There's actually a function to putting people through needless bullshit, though, which is that it helps companies monitor how compliant workers or potential workers are. Think of it like a canary in a coal mine situation. If you see someone balk at tedious make-work that person is more likely than other workers to put up resistance elsewhere or get involved if there's any kind of labor organizing forming. Companies have an interest in employing people who are as cucked as possible to minimize the success of organized labor. In porky's ideal world, people who have more rebellious tendencies are going to be relegated to gig economy jobs where they are maximally atomized and too precarious for resistance to seem like a viable option.
Mostly unrelated, but another sign of porky's power is the fact that you see a lot of interviews/applications where you're expected to do actual work for the company (for free). It's just another way of exploiting by getting around regulations for people who are considered employees on paper.
