A number of highly-trained workers from a large domestic airline have been reclassified owing to major technological changes in the operations of the airline - HSC - SSCE Business Studies - Question 6 - 2002 - Paper 1

The options are: (A) De-skilling: This refers to the reduction in skill levels required to perform a job due to advancements in technology. (B) Globalisation: This refers to the increasing interaction and integration among people, companies, and governments worldwide, which does not directly relate to the loss of jobs due to technology. (C) Inertia of managers: This suggests resistance from management to adapt to change, but doesn't directly relate to the workers' reclassification. (D) Resistance to change: This implies that employees may resist adapting to new technologies; however, in this scenario, it’s the technology that has made their roles unnecessary.

Given the context of the question and the changes affecting the airline workers, the best option is (A) De-skilling, as it directly relates to the reduction of skill requirements due to technology.
