It would be helpful to be able to set a max time frame for employees, then it would pop up a question on the app to the user to ask if they are still working on the job (perfect for end of day). That would help in the field to remind them to clock out of a job. Along with previous suggestion of not being able to clock into one job without clocking out of another one. If not, maybe have a review at the end of their work day, say 30 minutes after their normal time to leave, to review the times for the day.
