Hi Deepthi..
Before going for any Welfare activities, you must check whether it comes under company expenses for the same and it should not be overburdened.
Some of the welfare activities you may oragnise is below-
Birthday Celebration with cake cutting- You may celebrate B'day Party at last weekend of all those whose B'day was there in that month.. Arrange a big cake according to strength of your employees..
Employee of Month- During this B'day celebration, even you may celebrate the Employee of The Month Award also.. It will be awarded on the basis of performance of that individual in that particular month..
Arrange some Training programs, related with their personality developments, sales skill development, Communication classes..
You may celebrate Friendship Day...
Moreover if your employees are not covered under any Health Schemes, then you may ask them to enroll them with some Medical facilities, being provided by so many Insurance Companies.. It is available at a very low premium.. so company may also help to an extent..
