Technology

Labour is physical work but working your eyes and brain is also taxing. It's just a different set of muscles/organs. Sitting at the desk all day is also taxing. it's just not evident enough to people who see an AC and think that's comfortable. It's not healthy long term. Leads to all sorts of health issues.

Many of us tech workers joke that we will make our bag of money, retire, and go do farming. But you must understand why we joke like that.

For a lack of physical activity, desk workers suffer numerous health issues due to sitting all day/lack of movement. We are deprived of natural sunlight and wind in our badly lit offices staring at bright screens.

My point is that I said i felt isolated by blue collar workers not considering tech workers as the same class. You just went ahead and proved my point.

this is one of the reasons you don't see class solidarity from tech workers. The blue collar bunch think we are somehow same as the capitalist class.

Edit:

I also think the definition of labourer is not as myopic as you make it out to be. If one sells their time/works for money then they are labourers. Only those who make their money/capital/resources work for them cannot be considered labourer. Even a manager is a labourer. I would exclude CEOs because they invest and are also board members in their buddies' companies. Their employ is just a facade to maintain control and keep the power "within the family" so to speak.
