Each time we call, email, or fax a village
entity, someone has to receive the
communication, review and/or forward the
information, follow-up on requests, etc.
Whether it is to set-up a teleconference,
verify maintenance staff participation in
lighting or boiler trainings, set-up in-kind
lodging and transportation, lighting trainings,
track a shipment, verify completion of
lighting in a given building, ship lamps and
ballasts out of the village, request a labor
reimbursement agreement, or invoice etc,
etc. Village expenses for phone charges,
copying and fax costs, office supplies, etc
are part of this amount.
