Work–life and work–family balance refer to the harmonious division of time and attention between work and private life (Allen et al., 2000; Burke & Vinnicombe, 2005; Greenhaus et al., 2003). This harmony might be threatened in numerous ways. Expectations from work and private life might cause negative intrusion or spillover from one domain to the other (Byron, 2005; Staines, 1980). In other words, there is work interference with family (WIF) and family interference with work (FIW; Amstad et al., 2011; Byron, 2005). Spillover occurring in either direction can cause conflict.
