Hi Partner,
There are lots of things that can be continued during the home period. But then before you spring on to anything it is better to first check with your management on whether there is anything that they expect the HR to work on, on priority during this period and only if they are not sure then should you proceed ahead with your ideas.
My starting as an HR generalist was with a BTL marketing firm of hardly 16 members at the location. Most of my time used to be utilised in recruitment due to the high attrition, then attendance & leaves and then performance management and exits.
In my free time, I used to work on creating employee files containing details from their candidature applications, resumes, appointment letters, appraisal forms and ratings, leave records, awards, warning letters, relieving letters etc. With the hard copies stored in files, then I used to enter the details into the system for each employee creating a profile. Though there were only 16 employees, this was a never ending job because of the attrition level and the management was also happy because each file gave them a lot of data about each employee.
When you are working at home, I am not sure on how much of employee record access you may be having, but if possible this would be one area you can focus on, as this opens the door for the application of data and predictive analytics in future.
