I can see how physical labor is important in your company. I just meant to point out that in other settings, various skills are demanded. In particular, businesses which demand highly specialized skills don't often prioritize secondary skills highly. There are of course exceptions, like your company requiring both highly specialized skills and secondary ones. I don't know your setting, but I'd think the engineering qualifications vastly outweigh the physical ones. It's not as simple as two genders with equal intellect but unequal strength lend one gender more economic value. Individuals are hired, not genders (in general, not withstanding some exceptions). Individuals with unique resumes, skills, experiences, connections, and education - and that's what determines economic value today. A man with no engineering skills but significant strength is less valued in your company than a woman with engineering skills and little physical strength, I'd wager. The women (and men) landed and kept their jobs for reasons, probably not very related to gender equality. From what I know of you here, you are no doubt extremely capable and respected and should you be ranked, I'd bet your value at your company is very high.
Well, I don't want to direct the thread off topic, but I'll put a little more detail into the example.
The example was meant to be a microcosm of a possible environment, not a depiction of how all modern workplaces are. If anything, I tied the concept in more closely with older societies due to the shared importance of physical work in both scenarios.
The work we do is our facility. Rather than sell products, our service is our technical facility, with customized research equipment. It requires engineering development, as well as significant physical assembly, which due to the complexity, expense, and delicateness of the equipment, in addition to the size and weight, is often handled at least in part by the engineers that developed it, the specialized technicians, and some support workers that do only physical work. And fixing or updating the facility often involves the engineers, and often in a hands-on manner. (It's often easier just to do something yourself rather than explain to someone how to do it.)
I do not consider my workplace to be sexist. I was fortunately able to ascend into an engineering project leadership role fairly quickly. But in my assessment of women and men in the group, this is what I see:
-The women and men are basically equal in the highly complex areas of engineering development. The best workers are both male and female; no gender has an inherent advantage over the other.
-The men do have an inherent advantage in the secondary work which is largely physical. Some of it is biological: strength. Some of it appears to be cultural; I observe that women in the group have far less interest in crawling, climbing, using hand tools, using the machine shop, lifting heavy things, getting a little bit dirty, etc.
One programmer ranted to me that she often feels overlooked. As it turns out, she's always in a computer area doing programming, whereas the guy that sits next to her does quite a bit of programming but also gets visibility when he helps with very hands on things.
When a project leader is selected for a project that involves software, hardware, and significant physical construction/assembly/integration of the hardware and software, then the leader is often picked to be someone who has broad experience in these areas in addition to focused experience in their core area, rather than just focused experience. As it turns out in the group, that's often men.
