The impact of COVID-19 on illegitimate tasks across occupations in Sweden: a longitudinal observational study.
Observational study in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe COVID-19 pandemic led to major societal changes. Although the pandemic has significantly impacted the way we work, few studies have examined its effects on the prevalence of illegitimate tasks, i.e., tasks that are perceived as either unnecessary or unreasonable. Occupational groups were likely affected differently. This study investigates the prevalence of illegitimate tasks for registered nurses, teachers, IT specialists, and construction workers in pre-pandemic (2018), early-pandemic (2020), late-pandemic (2022), and post-pandemic (2024) periods.
methodsData were collected from biennial waves of the Swedish Longitudinal Occupational Survey of Health (SLOSH), corresponding to pandemic periods (pre-, early-, late-, and post-pandemic). We included four different occupational groups that vary in terms of socially critical activities, the possibility of teleworking, and the level of social interactions required in the job: registered nurses (n = 385), teachers (n = 412), IT specialists (n = 353) and construction workers (n = 313). We employed Generalized Estimating Equations (GEE) to assess changes in illegitimate tasks over time.
resultsOur longitudinal GEE models revealed that teachers reported a higher prevalence of illegitimate tasks than registered nurses, IT specialists, and construction workers. From the pre-pandemic period (2018) to the late-pandemic period (2022), all four occupational groups experienced a significant decrease in unreasonable tasks (adjusted for age), while unnecessary tasks decreased for all groups except teachers, for whom there was no significant change. By the post-pandemic period (2024), unnecessary tasks returned to pre-pandemic levels across all occupations, whereas unreasonable tasks remained at the lower, late-pandemic, level.
conclusionsThe level of illegitimate work varies across different occupations, with a higher prevalence in female-dominated, human service fields compared to male-dominated technical roles. Addressing the growing care needs with more human resources will be challenging. One possible solution is to increase available working time by reducing illegitimate and especially unnecessary tasks. Overall, this study contributes to a better understanding of how an important aspect of the work environment, illegitimate tasks, shifted during a period of major societal change.
