Dear Kathir,
As the first day of the week varies in different cultures, so does the week end. For example, Sunday is the day of rest and worship in the Christian or Western world. For Muslims it is Friday and for the Jews, Saturday is the day of Sabbath or worship. Thus week end or weekly off signifies the day of prayer or worship in religious sense and from employment perspective it is the day of rest. According to international standard ISO 8601, Monday is the first day of week and Sunday is the 7th and final day. If you browse the Net, you will find that Wednesday is the most productive day as it falls in the middle of the week. Therefore, I am a bit confused why it shall predominantly be the week-off for most of the employees in your organization.
