It is unattainable, from the perspective of the employer. As an employer, you just won't get those 8 hrs of productive work a day! Even if most employees can and do have more than 8 hrs of productivity, you just won't ever get more than 50% of that, no matter how many hours you pay them for. ...and it is OK. Yes, you have to pay someone for 8 hrs in order to get 4 hrs of useful work for you company out of them! Yes you have to pay for their side projects even if you like to pretend you don't! And yes you have to pay for people slacking at work... otherwise you don't even get that 50%! So, as an employer, accept this fact, pay up, and motivate your people to create awesome products that delight the consumers and bring record profits, in this limited amount of useful time that you can squeeze out of people!
