To increase the productivity of its attorneys, X law firm has decided to implement a part-time program, which would allow attorneys to have more flexibility in the number of days per week they work. Research has shown that giving employees the option of working part time is associated with increased company loyalty. The argument depends on the assumption that ['an increase in productivity is always signaled by a change in the number of days per week worked by employees', 'an increase in company loyalty may lead to an increase in productivity in the attorneys', 'all law firms will experience increased company loyalty by implementing a parttime program', 'attorneys are unable to fulfill their duties and maintain company loyalty']
