Frank makes a good point. While I work more than the 8.5 hours a day an earlier poster mentioned, I also mostly choose my hours and can hang out with the kids in the morning or afternoon before/after going in to work at weird times for global telephone meetings. So you have to measure the overall lifestyle and flexibility, not just when and how much people work.
I think the best companies will allow for people to work their 8 hour days and not be penalized. At the same time, companies should reward people who perform at a higher level and do more. Often this means putting in much more time. I also think that it's fair that a person should not expect to rise through the ranks working only 8 hours/day. That is essentially doing the minimum.
That's pretty much the way I operate too. Conference calls and even webex are easy to do from home or elsewhere, for that matter, and I take advantage of that too.
All the more reason to wonder how long I would stay at Yahoo, if I were one of those unfortunate employees. My question on that score being, if there were telecommuters who didn't perform, why punish the entire company? Just let the bad apples go.
I seldom leave work completely alone either during the weekend, at night, on vacation, etc. My company happens to have a very flexible policy towards telecommuting and I don't often notice the extra hours I put in.
I'd say my job never ends but that'd be misleading: it ends when I want it to end. As long as certain deadlines are met and I'm available to answer other designer's questions, there's really no time I "have" to work. The flip side that I put in whatever's necessary to get the job done.
I'd say that's a good trade-off. I'd like to think most engineers aren't trading time for pay; they're trading complete pieces of work for pay.
The most surprising thing about this is that 100% of those surveyed did not to some work on weekends and/or evenings. I can't think of a private sector job where that would not be the case!
There is another thing here, it is not necessarily about being a workaholic, but about being quality of product. It has generally been pride that has driven me. Pride in the quality of what I put out, whether product, process, management, etc.
I really don't consider having 2-3 evening conference calls per month with international colleagues to be a big deal. For the most part, my company is 8-5:30 give or take 30 minutes depending on the person, plus the random conference calls with Asian or European partners. We are lab-centric and are actually forbidden from being in the labs after hours or on weekends for safety reasons.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
