Do I need to sign a verbal warning?

Normally, the employer asks the employee to sign a verbal or written warning form to establish that they discussed the issue with you.  This prevents the employee from later claiming they never knew about this matter.  It is usually not intended to have you admit that you engaged in the alleged misconduct. There are occasions, however, when the employer is demanding that the employee sign and admit to the allegations and may even threaten to terminate the employee if he refuses to admit to this.  If you did not engage in the alleged misconduct, then you should not sign it regardless of the threats against you.  This is because that type of employer may later use that against you to block your unemployment or as evidence to support your termination.  Do not sign it if you disagree it.  If part of the incident is accurate but part of it is not, you would have the right to provide a written response stating where you agree and where you disagree with the accusations.
