Researchers also identified the strategies workers used to
manage the differences between the tasks formally assigned to
them and what the workers could accomplish given their working
conditions, including strategies used to reconcile their situation
with the state of the worker . All strategies and procedures were noted
along with potential situational determinants; these conclusions
were later checked for validity with participants. Determinants of
the activity were classified as to pole of service activity (Caroly and
Weill-Fassina, 2004).
