Maria: We need to hire more staffs. Tony: Yeah. There's too much work. Amber: Sticks? Maria: Huh? Tony: What? Amber: You say we need staffs. Maria: Right! T: Mmm. Amber: Look: staffs are sticks. Tony: "..." Maria: No, they're clerks. Amber: No; 'staffs,' with an `s` means "sticks." And the reason?  ANSWER: 'Staff,' as in "company staff" is a non-count noun, thus a company, restaurant or shop wanting to hire more workers must refer to them as staff, as not "staffs," as in:

Sony Hiring Additional Staff

Hiring Additional Staff

Most companies and restaurants--as well as other shops which put signs in the windows simply write:

Now Hiring

So every time you see a shirt in Japan or Korea that reads "Staffs", it can correctly only mean:

'the entire body of employees at several companies'

or...

'sticks'
