I'm absolutely a supporter of workers taking time off to maintain their mental well-being, but the idea that it's an acceptable and inherent bi-product of employers pushing workers beyond reasonable and healthy expectations of productivity is absolutely troubling.
That workers should spend their own sick days to cope with an ever-diminishing work-life balance rather than employers being forced to adhere to humane standards and expectations is absolutely maddening. We cannot accept a future where we're pushed to our absolute mental limits and have to choose when we can afford to spend a sick day to recharge.
