Final answer:
Partial work shifts in factory settings would be classified as restricted work activity since the employee did not fulfill their full work obligation.
Step-by-step explanation:
Days an employee was able to work a partial work shift would be classified as restricted work activity. In factory settings, workers were expected to work for a certain number of hours each day, typically ten to twelve hours. If an employee was only able to work for a portion of their shift, it would be considered restricted work activity since they did not fulfill their full work obligation.
