Dear Harini,
When you arrange cultural activities you should keep in mind that every one is been taken into consideration, there are many employees from different religion different region, different age group, different Grades and most important different Genders. So this part is most important than the arrangement.
As few members have already suggested few examples, I would like to just add few more.
The cultural program should be in combination of different activities and games
Games
Tug-of-war - Between different depts, Admin Staffs vs Prod Staffs or with different Grades.
Duck, Duck, Goose ! – For both Male/ Female employees
Rangoli Competition – For Females Employees
Matching Games – Tradition dress of there region
Concentration Games - For both Male/Female
Musical Chair – Group activity for Females
Performing Arts Programmes
Musical prog - Individual/Group
Dance prog - Individual/Group
Drama - Individual/Group
Other Programmes
Art and craft programs - For Female staffs
Sharing True Stories - Any individual
Cultural Trip
For the Staffs in a group
May be these help u in your cultural programs arrangements.
