I have 2 suggestions for your application. First, you can use the My Screen Recorder Pro scheduled recording to start and stop recording at a specific time. Each session will be a separate file. So you can schedule to start at the beginning of the work shift and end at completion of the work shift, creating a single file per day. Second, use the motion detected recording so you are only capturing operator actions. This will save on storage space considerably.
Finally, if you want to record continuously, you can rotate the recording files by using the command line options of My Screen Recorder Pro. More details on the command line options are available here:
