"A team of eight mail clerks sorts the mail&nbsp; into bins for each building.&nbsp;Next, the team fine sorts the mail in an area of the mailroom with floor-to-ceiling cubbyholes. Each little box is labeled with a unit number, and the mail is filed accordingly. Many have memorized most of the 700 unit numbers and many employees' names. After quick glances at the recipients' addresses, the mail flies out of their hands and into unit mail boxes."
