In response to the Covid-19 pandemic, Ministry of Manpower Singapore has been consistently reviewing and adjusting its guidelines with respect to Workplace Safe Management Measures (SMM). For example, according to the Workplace SMM on 14 May 2021, Work-from-home (WFH) should remain the default arrangement to minimise transmission risks at the workplace, and employers were urged to implement stagger start times and allow flexible workplace hours. Such policies and guidelines have considerably changed an organisation's operating process. Discuss the effect of WFH practice on the sustainability of an organisation's operations. The discussion should address the impact on each of the three (3) dimensions of sustainability. You should demonstrate critical thinking in the discussion and provide a balanced view on the impact of policy.
