My own experience: spent ten years in NMW entry level, often zero hour contract jobs. Retail, food delivery, factory work, food service etc. During that time worked on my skills, went into further education (all while continuing to work full time in the above jobs), then at 26 qualified in one of the professions and started to earn a bit better. At 26 my first graduate job paid £18k, and now at 31 I’m on around £40k. I work in mental health.
When you take a snapshot of my day to day work, I agree that a day of work now is absolutely nowhere near as ‘hard work’ as the day of work spent making pizzas in a takeaway or on a factory production line or selling computers to the public. It’s not even comparable. I have features of my job now that make it so much ‘easier’ in many respects: status, respect, flexi time so I set my own hours, the ability to work from home so I can work around life admin stuff, lots of freedom and mental stimulation. I don’t think I work as ‘hard’ as I did when I was in those previous jobs (though I’m paid more for my knowledge and skills and capacity to manage risk as opposed to what my body can achieve per hour as when I was shelf stacking).
BUT, what you have to take into account is the amount of work it’s taken to get to this point. Really, really hard work. While my colleagues at a department store might have only had that job as their main focus and then had free time outside to see friends, have kids, enjoy hobbies, i generally balanced working full time with studying full time for many years. So I’d get on shift at 5pm for pizza delivery having already worked eight hours that day at an unpaid placement or a voluntary job in the field I wanted to break into. When I finished at midnight my coworkers went home and slept while I stayed up until 3am writing a thesis for my course.
I’ve spent around six years full time studying at university to get to where I am now, plus other courses part time and voluntary work outside of the courses, and never let up on working full time simultaneously (notably a two year stretch of eighty hour weeks which almost killed me haha). So while I don’t think I work anywhere near as hard now as I did in NMW jobs, I had to work a hell of a lot harder to get here than most people I was working alongside at the time.
So sometimes pay doesn’t just reflect what you do in an average day, but what it’s taken over many years to get there.
