Dear Ekta,
You wanted to conduct swearing ceremony for the newly joined employees. But then would you mind to tell whose brainchild is this and why need was felt to do it?
The oath that elected representatives take is to protect the constitution of India (or constitution of that respective country, if it is a democratic country). If it is proved that the oath is violated then privilege motion is moved against the elected representative. Oaths are also taken by judges, senior level bureaucrats, armed forces personnel. However, the oath taking ceremony has legal sanction. In your case where is the question of legal sanction?
Through swearing in, it appears that you wanted to promote ethical conduct. However, there are other means to promote the ethical conduct. One is to live with the values of the organisation. Have you promulgated the values of the organisation? If yes, then have employees understood these values? Do employees perceive that organisation's values are respected in their organisation?
Second means of promoting ethical conduct to promote environment of justice. No person should feel that he/she has been let down. Have you done that?
You may give oath to the newly joined employees. However, what about violation of oath? What are the penalties attached? What about the transgression by those who joined earlier and did not taken any oath? What if a person takes oath and then you take him/her on task for his/her actus reus but find that he/she starts pointing out finger at others too?
Can juniors point out seniors for violation of oath? Will seniors get irritated because of this strange empowerment of the juniors? Have you thought of this risk?
It is important to create culture of openness and transparency in the company. In the town hall meeting of Google, any juniors is empowered is ask any question, if he/she feels that the company is not living with the values or their vision or mission statement. The brief that CEO gives to the Board of Directors is circulated across the organisation. They do not hide anything from their employees. This exactly is the starting point of motivation for Googlers. Therefore, your challenge is to create culture of motivation and a route of oath taking may not be that conducive for the culture formation. They could get weighed down by the invisible burden of the oath!
Thanks,
Dinesh Divekar
