I am sure that, somewhere, someone read this article on what office design says about your employees' happiness, and is currently drafting a memo similar to the following...
Per Business Instruction 3.5.17q, all employees are now required to greet the receptionist (Edit: What's her name again? We have it written down somewhere, right?) warmly in passing, but ONLY if a non-employee is in the vicinity. You are responsible for differentiating between a non-employee and current employees. Failure to warmly greet the receptionist in passing (or to greet without noticeable warmth) in the presence of a non-employee is grounds for reprimand, and possible termination of employment.
Wasting company time greeting the secretary in any fashion when a non-employee is NOT present shall be construed as a frivolous waste of company resources, and will be dealt with in accordance with the relevant regulations from the Innitech Employee Handbook, Chapters 9 through 14, inclusive.
Have a nice day.
