Across the developed world, a growing share of the population suffers from chronic disease such as diabetes, arthritis or heart problems – in the EU, around 45 per cent of those aged 55-64 had such a disease in 2015. And that affects their ability to work: just half of those with chronic illnesses are employed, compared to three quarters of those without. But how do the self-employed cope with such conditions, when compared with those in employment? Maria Fleischmann and colleagues from the RenEWL project find these differences in work status can make a major difference.
We know that when people become chronically ill, changes in their working conditions can help them to continue working. And we also know that good working conditions – being able to control how you use your time and how you do your job, whether you make the decisions and whether you feel valued, for instance – can help all of us to stay in paid work for longer.
And of course, if you become ill you’re more likely to feel the need to take time off or maybe to give up work altogether. We wanted to compare how the employed and the self-employed adjust their working conditions when facing a diagnosis of chronic disease.
Existing research tells us that many older people work for employers, and have to ask for their approval when it comes to making adjustments to their working conditions. The self-employed, meanwhile, are much more able to make their own decisions and tend to feel they have more control over their working lives.
We looked at people’s ability to control their work: physical demands, working hours, psychological demands such as how fast they had to work, and social aspects such as whether they felt valued.
And we had a great source of data for this – the English Longitudinal Study of Ageing (ELSA), which has followed a total of almost 9,000 over-50s since 2002.
From that group we were able to find and study 1389 participants who reported no chronic diseases when they were interviewed in 2004-5 – the second wave of interviews – and who were in work. We were then able to look at what happened to them before the seventh wave of interviews, in 2013-14.
A little over 40 per cent of our sample were in managerial or professional occupations, a quarter in intermediate occupations, and almost 30 per cent in routine and manual occupations.
At each interview, respondents were asked whether they had been diagnosed by a doctor with lung disease, asthma, arthritis, cancer, high blood pressure, diabetes or high blood sugar, stroke or heart problems.
During the study period 510 of the 1389 sample members were newly diagnosed with one of those conditions. We were able to look at how they fared at work for four years after that, and we found some striking differences between how the employed and the self-employed seemed to have been treated.
The physical demands of our participants’ jobs were pretty similar before their diagnosis, for instance. But afterwards significant numbers of those who were employed said that those demands had actually increased when they were diagnosed. The self-employed, meanwhile, told us the opposite had happened to them – they reported significantly lower physical demands at work immediately after diagnosis. This effect continued for some time, though it grew less pronounced.
How could that be? We think maybe the increase in physical demands among the employed could be due to perception – similar demands might be perceived as more strenuous by the chronically ill. The self-employed, meanwhile, have more freedom to adjust those demands when they feel they need to.
The self-employed reported that their working hours dropped by an average of 2.8 hours per week on diagnosis, while those who were employed did not see a change. This effect was not statistically significant, though.
Employees found that their level of autonomy at work also dropped marginally, while for the self-employed there was no significant change. We did not find any major changes in psychological or social conditions in either group.
So, what did we learn? Essentially, that improvements in working conditions after diagnosis of chronic illness were restricted to the self-employed. So employers may need to ask themselves some hard questions – do they want to hold on to workers who become unwell? If they do, then they should consider the levels of flexibility they offer, and they should think about making adjustments for those workers if they don’t want to lose them.
In an ageing society, older people are expected to work ever longer and therefore to remain at work even when they begin to suffer from health problems. Our findings should also encourage policy-makers and governments to think about how chronically ill older adults are treated at work.
