Overtime

Overtime. Let me teach you the O3 way of gaining as much OT for free from your staff.

Technique 1: Pay for no overtime = Free labour.
Technique 2: 5 mins before the end of work, call the staff into your office to discuss some minute matter. Call more staff in for the same purpose at the same time. With such a large number of people in your office, by the time you are done and they leave together, it will be a good 30 mins after work.
Technique 3: Fine staff for arriving to work late. Use a punch card to monitor these times regardless of whether they are paid by the hour.
Technique 4: For staff to avoid further fines, they must work 3 times the duration they were late for.
Technique 5: Stare at staff who leave on time disapprovingly as they walk past your office.
Technique 6: Force staff to stay back by the sheer amount of work they have to do - usually 2 person's job.

By following the above, you get:
free overtime from staff = free labour and savings for the company. (c.f. a penny saved is a penny earned)
