And please don't anyone get me wrong, I'm in no way saying "Lol fuck these struggling cunts, fuck the poors!" or "Lol minimum wage is enough just do your jobs", I am not. I am 100% behind Fuck-you-I-ain't-going-above-and-beyond-for-a-pittance*. If you get paid $15/h, give your boss not a single fucking penny more than $15/h's worth. If you're in the US and get whatever $7/h bullshit arsed shit you all haven't rioted about yet, then by all means give your boss not a single penny's worth of labour above $7/h.
But there's a difference between 'doing 125% when you're being paid dogshit wages and the company gets extra labor out of you for free' and 'well I don't care about this job so I'm not even going to attempt the literal minimum.' If you're getting paid $7/$15 per hour, you do need to at least give $7/$15 worth of labour, not $3.5/$7 worth.
