Work-home interference and work-family conflict have been defined as ‘‘a form of inter-role conflict in which the role pressures from the work and family domains are mutually incompatible so that participation in one role [home] is made more difficult by participation in another role [work]’’ (Greenhaus & Beutell, 1985, p. 77).
“Work-family conflict is produced by simultaneous pressures from work and family roles that are mutually incompatible (Greenhaus & Beutell, 1985; Kahn, Wolfe, Quinn, Snoek, & Rosenthal, 1964). Because of incompatible role pressures arising from the work and family domains, effectiveness in one role is hampered by experience in the other role. In other words, work-family conflict occurs when experiences in a role interfere with meeting the requirements and achieving effectiveness in the other role (Edwards & Rothbard, 2000); Greenhaus & Beutell, 1985). Therefore, the essence of work-family conflict is inter-role interference, and work-family conflict could just as easily be referred to as work-family interference” (Greenhaus, Allen, & Spector, 2006).
