If it's important you'll get a call. When I do work at a place that prides itself on people being available around the clock, i'll delay send / reply to something right before bed and then plugging in my phone in another room.
Gives the appearance of working the most hours, interrupts other people / ruins their sleep, doesn't really affect my life in any material way.
It's a shame that the concept of "having a life" as we pejoratively said in the 90s seems to have been forgotten.
That used to be something that society would spit in the face of the fat pigs for. But, now, it's considered sensible everyday practice that none would question. Of course Walmart lets the government shoulder a portion of the compensation of their workers through food stamps. Of course the fact technology enabled employees to produce 40% more value this year results in a raise of 1 or 2%, less than the cost of living increased. Of course they take and take and feel absolutely entitled to every penny of the billions in profit.
At the same time they claim to believe in the principles of a free market. At the same time the free market principles declare that all profit is a mistake, that all profit should quickly go to zero in any sensible market. Huh. Imagine that.
But I agree that a lot of big players have managed to position themselves outside any 'free markets'
