The real guestion that must be asked is why was he hired in the first place? Would not have been difficult to uncover a history of problems he had in previous jobs.
Wonder how he reacted to the word ‘Ho.’
Because of the legal environment, an employer must never reveal WHY an employee was let go. . . never. The most you can say is that, yes, he/she was employed at your business and they were employed from such and such a date to such and such a date. You may be asked "Would you hire this employee again?" to which you may voluntarily answer "Yes" or "No" but it is not advised to answer one way of the other. . . and never give a reason unless the answer is "yes." For this reason, we never fire an employee unless police are involved, we merely "lay them off" and any reason is a change in business conditions or plans. You don't provide any reason for legal action.
