Norwegian Cruise Line’s “Undercover Boss” episode featuring CEO Kevin Sheehan is airing again at 8 p.m. and 11 p.m. ET Aug. 18 on TLC. The episode has already aired several times and been viewed by more than 35 million people. This time, Norwegian is offering “The Boss is Back” promotion that gives $200 onboard credit per stateroom to those who book a cruise on Norwegian Epic or Pride of America by Aug. 19. Also, reduced deposits will hold all cruises of three days or longer.

“I learned so much during my ‘Undercover’ experience,” Sheehan said. “Even now, more than a year later, I continue to be humbled and appreciative of how our crew makes every day memorable for our guests. I’ve also continued my ‘Undercover’ journey by making a point of visiting all of our ships on a regular basis.”

This year, Sheehan has visited nine of Norwegian’s 11 ships and has met thousands of crew members and guests. He has placed a major focus on crew welfare and training and has introduced initiatives based on feedback he receives. Most recently, the company is expanding bandwidth for crew, along with lowering telephone and Internet rates, making it easier and more affordable for crew to keep in touch with their families.

“My mission since filming ‘Undercover Boss’ has been to listen to our crew and make adjustments to ensure that they have the appropriate tools to do their jobs, feel appreciated and, very importantly, can keep in touch with their families and friends while onboard,” Sheehan said.

The episode originally aired in 2011 on the CBS Television Network and featured Sheehan in uncharted territory aboard both Norwegian Epic and Pride of America when he’s asked to lead nearly 1,000 party-goers in a line dance. Later, he is forced to reveal his true identity after being recognized by a crew member.

“Every time the episode airs, I receive a flood of emails from guests who tell me how much they loved the episode and how much they are looking forward to cruising with us,” Sheehan added.

In addition, Sheehan will take questions via Twitter during the promotion through Aug. 19. Twitter users can tweet questions or comments to @CruiseNorwegian using the hashtag #TheBossisBack.
