What a load of nonsense. In the U.K., the safe maximum load for a single lift from the hips is 25kgs. HSE will come down on you hard if you have people regularly lifting heavier weights than that. Almost all groundworks and trenching, demolition etc is done by machine, you’d struggle to find a single pick axe on a construction site. It does employers no good to have people of any gender heavy lifting regularly so most will prevent it. Not to mention the plethora of non heavy work that happens on site. Joiner, carpenter, painter, electrician, mech install, tilers, floor laying etc etc etc.
Offshore work similarly is not as heavy duty across the board as it once was. I know of many women who have worked offshore, chemists, analysts, medics, catering, well monitoring, welders. Most heavy work is also mechanised these days. One of the busiest places on a rig is the gym.
Mining and tunnelling - again largely done by machine. Tree surgery, as long as you can lift a chainsaw you’re fine. The myth that these are all dirty back breaking work is peddled largely by the men who do these jobs, usually as an excuse to either keep women out, or to avoid doing anything around the house. This also serves to keep the pay gap going strong because the financial value of similarly difficult work traditionally done by women is less. Thankfully the law is correcting that now. It is no longer possible for a street sweeper to be paid more than an office cleaner.
The main reason women don’t enter these careers is because they are socialised to avoid them. Most who do, face a toxic working environment not because of the job, but because of the men they are working with.
The big issue with the gender pay gap has very little to do with any of those “heavy jobs”. It is because women are prevented from progressing to managerial roles. There’s a reason for that…
