Kevin Hart -- Makes Plea to Save Bus Driver's Job

There's nothing Kevin Hart won't do for his fans ... including saving one of them from getting fired -- he just recorded a plea to the rental car company that suspended a bus driver who took a selfie with him on the job.

We broke the story ... Genesha Bradley-Douglas was suspended without pay after she stopped her National Car Rental shuttle bus at LAX and jumped off to snap a quick shot with Kevin.

Kevin is now begging National to put Genesha back on the payroll, telling the company ... "C'mon have some compassion!"
