Final answer:
Kevin can strengthen his wrongful discharge case by negotiating a severance and collecting evidence of any employer promises, but not by allowing intimidation or using company property as leverage.
Step-by-step explanation:
Kevin's chances of prevailing in a wrongful discharge suit against his employer may improve by negotiating a severance package, providing evidence of any promises made by the employer, and collecting proof to support those promises.
However, allowing the company to intimidate him or keeping company property as a bargaining chip would not benefit his case and could be detrimental. It is important for Kevin to engage in actions that support the legality and morality of his claims of wrongful discharge.
