Then again, they realise that we generate about 650k a year in real hard cash per head which is pretty good :) That's how a company should look.
we have to buy our own lunch though and spend our spare time doing some reading and self tuition.
Mayer's explanation should really be read like this:
Employee X has been working 130 hour weeks for the past month. He's looking more than a little worse for wear; he's probably going to burn out soon. Let's sit him down for a chat and make sure he's doing okay. Oh, he's been missing his daughter's soccer games to manage a critical deploy, and those soccer games are super important to him. Alright, let's deal with that. Mandate that someone else take over, de-prioritize the deploy, rework the process so that deploys happen on a different day or a different time... whatever it takes. He might still be working 130 a week, and that's not great, but he gets the critical thing he just can't miss.
This meme is dangerous not just because of the effect it has on people who don't subscribe to this, but also because it is just plain wrong. People who work longer hours are not more productive and they do not get more done. Its a simple case of measuring input (hours spent) instead of output (quality code, decisions whatever...), because measuring what matters is not very straight-forward.
I know the statement above doesn't have backing data, just my experience/ observations, but have you seen anything to contradict this statement?
In the office I work in, it is virtually empty at 8:00 AM and mostly empty by 7:00 PM. Most people seem to show up around 9:00 AM and leave around 6:00. On Fridays, the office mostly stops working around 5:00 PM.
There is a cadre of people, typically those without families, who stay a bit later but it often seems like they stay just long enough to eat the free dinner and then head home. Those people often also show up around or after 10:00 AM.
There is variation from project to project and office to office, but the work life balance seems very healthy in the offices I've seen. I have kids and a long commute, so it's important that I don't work late and I've never felt the slightest pressure to work more hours.
