Linux, politics, and other interesting things
I have just read an interesting article titled Why Crunch Mode Doesn’t Work  which documents the research on efficiency vs amount of time spent working (and by inference amount of time spent on leisure activities and sleep). It shows that a 40 hour working week was chosen by people who run factories (such as Henry Ford) not due to being nice for the workers but due to the costs of inefficient work practices and errors that damage products and equipment.
Now these results can only be an indication of what works best by today’s standards. The military research is good but only military organisations get to control workers to that degree (few organisations try to control how much sleep their workers get or are even legally permitted to do so), companies can only give their employees appropriate amounts of spare time to get enough sleep and hope for the best.
Much of the research dates from 80+ years ago. I suspect that modern living conditions where every house has electric lights and entertainment devices such as a TV to encourage staying awake longer during the night will change things, as would ubiquitous personal transport by car. It could be that for modern factory workers the optimum amount of work is not 40 hours a week, it could be as little as 30 or as much as 50 (at a guess).
Also the type of work being done certainly changes things. The article notes that mental tasks are affected more than physical tasks by lack of sleep (in terms of the consequences of being over-tired), but no mention is made about whether the optimum working hours change. If the optimum amount of work in a factory is 40 hours per week might the optimum for a highly intellectual task such as computer programming be less, perhaps 35 or 30?
The next factor is the issue of team-work. In an assembly-line it’s impossible to have one person finish work early while the rest keep working, so the limit will be based on the worker who can handle the least hours. Determining which individuals will work more slowly when they work longer hours is possible (but it would be illegal to refuse to hire such people in many jurisdictions) and determining which individuals might be more likely to cause industrial accidents may be impossible. So it seems to me that the potential for each employee to work their optimal hours is much greater in the computer industry than in most sectors. I have heard a single anecdote of an employee who determined that their best efficiency came from 5 hours work a day and arranged with their manager to work 25 hours a week, apart from that I have not heard any reports of anyone trying to tailor the working hours to the worker.
Some obvious differences in capacity for working long hours without losing productivity seem related to age and general health, obligations outside work (EG looking after children or sick relatives), and enjoyment of work (the greater the amount of work time that can be regarded as “fun” the less requirement there would be for recreation time outside work). It seems likely to me that parts of the computer industry that are closely related to free software development could have longer hours worked due to the overlap between recreation and paid work.
If the amount of time spent working was to vary according to the capacity of each worker then the company structures for management and pay would need to change. Probably the first step towards this would be to try to pay employees according to the amount of work that they do, one problem with this is the fact that managers are traditionally considered to be superior to workers and therefore inherently worthy of more pay. As long as the pay of engineers is restricted to less than the pay of middle-managers the range between the lowest and highest salaries among programmers is going to be a factor of at most five or six, while the productivity difference between the least and most skilled programmers will be a factor of 20 for some boring work and more than 10,000 for more challenging work (assuming that the junior programmer can even understand the task). I don’t expect that a skillful programmer will get a salary of $10,000,000 any time soon (even though it would be a bargain compared to the number of junior programmers needed to do the same work), but a salary in excess of $250,000 would be reasonable.
If pay was based on the quality and quantity of work done (which as the article mentions is difficult to assess) then workers would have an incentive to do what is necessary to improve their work – and with some guidance from HR could adjust their working hours accordingly.
Another factor that needs to be considered is that ideally the number of working hours would vary according to the life situation of the worker. Having a child probably decreases the work capacity for the next 8 years or so.
These are just some ideas, please read the article for the background research. I’m going to bed now. ;)Best Posts, Most Popular
