ESPN's Britt McHenry -- Back to Work ... I'll Never Be Rude Again!!

ESPN reporter Britt McHenry is finally back to work after serving a week-long suspension for berating a tow truck employee ... and she SWEARS she'll never bitch anyone out again.

McHenry has been assigned to cover the NHL playoffs ... but before she goes back on the air, she issued ANOTHER apology.

"Now that the suspension is over, I want to say again that I'm so sorry for my recent hurtful actions."

"My remarks were completely out of line. Under no circumstances is it ever acceptable to speak to another human being in the manner in which I chose that night."

"That's not who I am as a person and hope those who only know me from this incident will give me a second chance to prove to you how much I value integrity, character and treating people with respect."
