If a bill collector keeps calling your job after you told them not to can't you report them somewhere & where

Can't they be reported for harassment
Yes they can be reported to Federal trade commission. In this case you can say that the next time they call you at work you'll be recording the call and be reporting them to the FTC due to the federal fair collections act. Then you'll be filling a civil suit as well.
Why don't you just pay your bills..and don't give out your work number


Answers:
Yes. It is illegal for them to keep calling you at your place of business after they have been notified that they should stop such actions. Read the Fair Debt Collections Practices Act. It's dry but very informative. Violations of such Act can be used for grounds of a lawsuit in small claims court for $1000. If they keep calling file a complaint with the FTC and your state AG.
Yes that is a violation of the fair credit reporting act. Talk to your state department of commerce first and they may refer you to the federal level.
Here is an excerpt but you can read the whole article at the web address provided. They cannot legally contact you at work if you tell them you cannot take these calls at work.

ยง 805. Communication in connection with debt collection [15 USC 1692c]

(a) COMMUNICATION WITH THE CONSUMER GENERALLY. Without the prior consent of the consumer given directly to the debt collector or the express permission of a court of competent jurisdiction, a debt collector may not communicate with a consumer in connection with the collection of any debt --

(1) at any unusual time or place or a time or place known or which should be known to be inconvenient to the consumer. In the absence of knowledge of circumstances to the contrary, a debt collector shall assume that the convenient time for communicating with a consumer is after 8 o'clock antimeridian and before 9 o'clock postmeridian, local time at the consumer's location;

(2) if the debt collector knows the consumer is represented by an attorney with respect to such debt and has knowledge of, or can readily ascertain, such attorney's name and address, unless the attorney fails to respond within a reasonable period of time to a communication from the debt collector or unless the attorney consents to direct communication with the consumer; or

(3) at the consumer's place of employment if the debt collector knows or has reason to know that the consumer's employer prohibits the consumer from receiving such communication.
