confrontation interviews. For the auto-confrontation interviews, a
fifteen minute video was edited combining short sequences from
the two waves of observation. The video sequences chosen illustrated
(1) common tasks, (2) tasks that seemed difficult or problematic
(such as awkward posture, quality rejection), (3) use of
various equipment and (4) training situations. Two other types of
data were presented to the participants: (1) shift chronicles
(sequence and duration of workers’ tasks during the two observation
days) and (2) individual injury reports (including musculoskeletal
symptoms). For the allo-confrontation interviews, the
preparation differed slightly. A video was also prepared and
included common apprentice tasks, situations that seemed diffi-
cult, and apprentice tool/equipment use. However, more emphasis
was put on training situations involving ECs.
For both allo and auto-confrontation interviews, the participants
were first asked to freely comment on the videos or the data
shown. Afterward, they were asked to answer a set of open-ended
questions. These questions were adapted for each interviewee to
correspond to their own situations. However, all participant interviews
addressed the following topics: nature of work tasks, diffi-
culties encountered, teaching and learning processes, OHS
hazards and injury experiences.
All data collection was conducted in French. Interview transcripts
were translated to English by the lead author, and with
the interpretive assistance of the English-language research team.
