Toni, who did not want to provide his last name, was the manager of the food and bar section at The Anchor Inn in Wyre Piddle when a man died in a boat moored at the pub.
A man in his 30s was found dead at the scene of the boat fire in the early hours of Christmas Day.
The manager said: “The tragedy on Christams Day left me unable to continue the business.
“Someone has lost their life.”
He added that the incident had affected him mentally, physically and financially, and the decision was for the best.
Police received a call at around 7.32am on Christmas Day to a boat fire on the River Avon at The Anchor Inn where a man was pronounced dead at the scene.
The man’s death is being treated as unexplained, with early indications being that it was not suspicious.
Worcester News has contacted West Mercia Police for an update.
Toni added: “For the last nine months of being part of this incredible journey, the time has come for me to move on to new opportunities.
“As I prepare to take on my next chapter, I want to take a moment to reflect and express my heartfelt gratitude.
“To my colleagues, clients and everyone I’ve had the privilege of working with, thank you for your support, collaboration and the many lessons along the way.
“It has been an honour to contribute to Wyre Piddle and The Anchor Inn and to be part of such a talented and passionate community.
“I will truly miss the connections and memories I have made here.”
During Christmas Day, police conducted door-to-door enquiries into the incident.
One resident, who was shocked by the incident, said: “I heard what I thought was an odd noise, then I could smell burning, but I didn’t hear or see anything connected to the pub.
“It was terribly tragic, especially on Christmas Day.
“I was due to go to the pub for lunch and the man who owns it called me up to say what was happening and that he couldn’t re-open.
“I really appreciated that touch from him.
“I don’t think there is anything worse than to lose someone you love, but it makes it doubly sad being around the holidays.”
