Why Does The Worker Give A 1 Month Notice?
Professional notice protects your professional reputation.
Up to the point of notice, projects and tasks have been assigned which will require a month to wrap.
This month also moves the overseers from:
"investment" mode, in which they invest valuable time, responsibility, and training in a helper,
"Wrap it up" mode, in which the helper is simply finishing what they've started.
Notice protects the management from students just sponging a costly "free" education, then leaving before they actually contribute something to the "mission".
Month 1 = supervisors invest expensive time in helping the student find and communicate his/her focus;
Month 2 = the student's and supervisors' investments begin to balance;
Month 3: The now trained and focused ex-student neo-professional begins to pay back the supervisor's time.
