physical labour is a literal strain on your body. historically this has been a given of certain forms of labour, eg, even before the official recognition of disability, mine workers in many parts of the world received disproportionately high wages compared to other jobs because it was understood that your body would break down by the time you were 40-50 and you wouldn’t be able to work anymore. the high wages were for supporting you after that, but they were only present where unions had been able to force this demand on bosses; there’s a reason mine working has historically been a common form of slave or indentured labour. this example is an obvious one (and one i wouldn’t want to rely on for various reasons) but if you’ve worked stocking supermarket shelves, or cleaning, or as a barista, or as a farm labour, you will know that being on your feet for hours on end, the repetitive movements required to complete tasks, the strain of constant attention, these all take their toll
work environments are stress inducing and long term stress has both physical and mental effects. it can change how you approach other people, how you regulate your emotions, how you relate to social settings. stress can produce strains, it can produce headaches, it can produce tightness in muscles that are can cause injury
when you need to work to provide food, rent, clothing for yourself, you are not as able to protect yourself from health and safety risks. you are more exposed to disease and to other health risks, depending on the job, and you are less able to effectively rest and recover, thus increasing the likelihood of long term complications
disability is class enforcing
being disabled is expensive. simply getting healthcare at all can be prohibitively expensive for many people. this is not even to mention mobility aids or other specialised equipment. you may have to spend more on specialised diets or accommodation. you may need to hire personal assistants or other forms of labour to complete certain tasks for you
there are less jobs that you are able to work. you are less likely to be able to work long term. you are less likely to be able to work longer hours, and your partners may also have to work shorter hours to care for you. you are more likely to be forced into precarious employment or onto benefits which, which available, are pitifully small
you are more likely to face job discrimination and more likely to face housing discrimination. the housing you are able to get is likely to be more expensive
you are more vulnerable to abuse, either domestic, or in public, or by the state. this is increasingly the case if you are Black or a migrant or a woman or trans or homeless, etc, and it’s increasingly the case the more poor you become
this is not a complete list, it’s just what i could think of off the top of my head (and i just woke up too lol). i hope that clarifies some of the factors i am thinking of here. feel free to ask if there is anything that is unclear
