"As introduced, provides that when the department of labor and workforce development conducts unemployment hearings that personnel records and other business records that are in the possession of a claimant’s employer and that are relevant to a claim shall be admissible, regardless of whether such evidence is hearsay or whether corroborated by direct witness testimony, if such evidence is accompanied by an affidavit of its custodian or other qualified person certifying the evidence as a business record. - Amends TCA Title 4 and Title 50."

Typically, an employee who is fired for cause can't claim unemployment benefits. When an employee is fired without cause, for example laid off for economic reasons, they are entitled to file for unemployment. Unemployment claims affect an employer's unemployment insurance liability and can result in premium increases.

So basically, with this new law an employer can fire someone without cause and then make stuff up to deny the claim and avoid unemployment insurance premium increases. It also takes away the employee's right to due process and their ability to confront witnesses against them.
