New Job Data Analyst

Hello Everyone, So I recently was hired as a data analyst for a small hospital group managing mostly nurse practitioners but also doctors and nursing homes. I am responsible to analyze working hours, patient inflow, site wise analysis and stuff like that.

For this I was given a part time (20 hours) role with high possibility to turn full time soon. Since its been only a month, most of my work has been cleaning data, validating data and making sure data is input in the correct manner so id save time during analytics.

However, im concered by the way I am working, I feel like like in 2-3 months i will have to spend only 7-8 hours every week to get the job done since now the data is cleaned and I dont have to spend time understanding the dataset.

I did discuss this issue with team lead who laughed and said im sure we always have something to do here so dont worry.

One of my friends recommended that I work normal/slow (I often do tasks very quickly) and dont tell others that you dont have tasks to do. But I am not satisfied if Im nt doing anything at job. Plus i work in person for 20 hours so I have my team lead sitting behind me monitoring my activity. Cannot just sit idle.

I am planning to approach my manager who is the owner of the business (very kind guy) and ask him if I could help with something else too after I find time.

How do you guys spend time as a data analyst, do you have enough, and if you end up doing things how do you manage bringing tasks yourself or what else do you do to keep you busy so you can justify the hours.

Please help !
