answer:No. Or at least I HIGHLY doubt it. There is no “list” that all employers go to to see if you performed badly for past employers. Staffing agencies do have black lists, but if you go through a different agency, or pass them up all together, you will avoid being black listed. Now if you’re using your past employers on your resume/application, they could very well be giving you a bad reference. But Toys R Us lacks the ability to check your entire work history, they can only see what you give them. (employment history doesn’t even show up on back ground checks).
