Contracts — Employment — Argument — New trial — Defendant’s closing argument was improper and highly prejudicial where it advised the jury that defendant had evidence that had not been presented to the jury and improperly stated that the jury’s inability to receive said evidence was unfair to defendant — Defendant’s argument also impermissibly implied that additional evidence would have been favorable to defendant and that the jury should recognize that defendant had the benefit of more information in deciding whether to terminate plaintiff’s employment — Trial court’s failure to sustain plaintiff’s objection to defendant’s improper argument constituted harmful error — Remand for new trial
