Workforce competitiveness trends have shown significant changes over the years. Multiple role conflicts have seen an increase in both dual-earner families and single-parents. Regardless of whether it is single parents or working couples, both must manage family and work obligations daily. As such, many companies are adopting flexible working arrangement in their organizations. This study aimed to discover the moderating effect of supervisor support on the flexible working arrangement and work-family conflict relationship. The population for the study consisted of Malaysian organizations that adopted a flexible working arrangement. The flexible working arrangement here includes adoptions of flexible working time, compressed work-week practices and working from home. The companies involved were derived from TalentCorp Malaysia Flexible Working Arrangement report, 2015, in collaboration with Malaysian Federation Employer. The surveys form would be disseminated to the organization selected from the list through their respective Human Resource Department. The findings would explain the moderating effect of supervisor support on the flexible working arrangement and work-family conflict relationship. Findings from this study are deemed to be beneficial for the employers in general and human resource ministry in overcoming the turnover of productive employees due to the inability to balance work and family needs. The findings would also minimize the brain drain suffering by Malaysian organizations. An effective strategy could be developed so that the work-family conflict issues could be overcome.
