I recently started a new job. I love the work that I am tasked to do and for the most part I really like the organization and most other people that I work with.

My supervisor asked me in the interview if I would not mind training other colleagues to do my job to help with their capacity development. I said I was fine with this as I really wanted the job.

In the three weeks since I started I have found my colleagues apathetic about their jobs, and they do not equally share information with me regarding their roles and responsibilities. However, my biggest concern is training a colleague to take over and do my job. Additionally, my colleagues have been working with my supervisor longer than I have and they already have a good relationship with my supervisor.

I work in a small department, so I have no other choice but to train these colleagues. What perspective should I take on being asked to train other colleagues to do my work – is this a good thing or a bad thing? How should I proceed to train such colleagues, yet ensure my own job security in the future?
