As mentioned above, 14 out of 18 test persons are employed. Accordingly, only 14 test persons (TP 01, 02, 03, 04, 05, 06, 07, 08, 09, 11, 13, 14, 15, 16) were asked how many hours they had worked in the week before the pretest. Nine of them (TP 01, 02, 04, 07, 08, 09, 13, 15, 16) actually worked and were therefore able to provide direct information on the question. Four respondents (TP 03, 05, 06, 11) were on holiday and could therefore only make an estimate based on previous weeks. TP 14 also had to give an estimate because she was ill. From the spontaneous comments of the test persons, various problems regarding the answering of the question become apparent. For one thing, it is not clear to the test persons whether the contractually agreed working time is asked or the actual number of hours worked:
"Formal or actual? If it is not further specified, I would state the formal working time simply because I do not have to think about it. The formal working time would be 40, the actual working time would be higher, more than 50 hours. But in response, I would give the formal working time here, just when I am short. With the actual one I would have to think longer" (TP 07). In addition, another problem can be taken from the statement, which is also reflected in the statements of other test persons. Some test persons find it difficult to remember the exact working hours. Therefore, it can be assumed that they too - as TP 07 already mentioned - tend to give formal information, unless the wording explicitly asks for the actual hours.
- "Normally 39.5 hours, but due to the order situation we often work on weekends." (TP 02)
- "I'm not sure. I reduced. I’ll say 35. That’s the regular number of hours. I've reduced it to 80%." (TP 08)
- "It varies every week, 75% I work there. That's why the average is 30 hours a week. Correspondingly. So, it's distributed according to the week. Sometimes there's a weekend shift, sometimes not, and accordingly it's sometimes 34, sometimes 26 hours. Depending on that." (TP 15)
