I am currently working on analysis problem where I wish to assess the impact of overtime work on sickness levels in a company. I currently have the data stored by week for each employee over the last 2 years.
My hypothesis is the following: Over time (additional work hours) increases the likelihood of sickness for each employee. Null Hypothesis: Past overtime has no impact on sickness levels. 1 row has a similar layout to this:
Week 1 Employee A 1 Hour Sick 12 Hours Overtime
As each observation takes the current sickness and overtime I am unsure how to create a model which tests the impact of past overtime on current sickness.
If anyone has dealt with this kind of problem before and identified a good statistical method then your advice would be appreciated!
