Does the employee interactively specify the "work type" then some
time-spent value?

Can the work-type be chosen from a drop-down generated by

    select work_type from table where employee = <current user>

Otherwise you'll need a trigger on the insert into "enter their work"
table.  Sad thing here is the user has likely left the scene.
