		Values, n (%)	Number of excerptsa
Work-related barriers (n=2)b
	Time-consuming work life	29 (73)	69	Participants experienced the tasks in everyday work life as time-intensive and inflexible because of weather influences, seasonal tasks, and work peaks and thus, as challenging for IBIc participation.		“So actually, only operational work that is...very time-intensive and can’t be postponed...harvesting work or something like that, where you...say that HAS TO BE now. Now there is simply no time at all for three days.” [Interview 34]
	Lack of staff leading to high workload	4 (10)	5	The (unforeseen) shortage of staff was experienced as aggravating for the workload, and thus, as challenging for IBI participation.		“This is a very special case, we don’t have an apprentice this year and so there’s a lack of manpower at all corners and then there’s the bad conscience again because the work doesn’t get done.” [Interview 17]
Work-related facilitators (n=1)d
	Flexible time management at work	25 (63)	34	Flexible time management at work (eg, because of self-employment, pension, lease of land, downsizing of the company, low workload, and season) made it easier to participate in the IBI.		“Yes, simply that you are self-employed, that you can arrange your work freely.” [Interview 20]
