On the other hand (isn't there always another hand?), there could be a check-cashing scenario in which you'd have to file a CTR. It's admittedly rare, but I've seen it happen. It's a variation on the scenario suggested by Richard.
Suppose that XYZ company, rather than losing employee time to bank visits (for some reason they don't successfully offer Direct Deposit), provides a service whereby employees who want their checks cashed endorse them and give them to a "runner" to take to the bank. The runner then cashes all the checks and places the proceeds, along with the check stubs, in payroll envelopes for return to their rightful owners.
In this scenario, there might be more than $10,000 cash paid out at once. So you'd have to complete a CTR based on who transacted the business (the runner), who would be fully identified in Part I, Section B of the form. And, of course, you are then stuck with multiple Section A entries, one for each of the payees. And you won't have much info for Section A of the form unless you have a cooperative employer who supplies all that information. Finally, if you have more than three checks, and you're filing paper CTR forms, you'll need to attach blank sheets (see the instructions with the form) with the additional payees' information.
For obvious reasons, you don't want to encourage this practice. But if you have an employer who insists upon it, try to have the employer complete Section A of the CTR forms for you (with payee information complete) or at least supply all the information needed.
