Titan Travel has confirmed it will be making redundancies following a structural review of the company.
Managing director Andy Squirrell said "a number of colleagues" would leave the business, but declined to discuss numbers.
Squirrell paid tribute to the efforts of the operator’s staff to rise to the challenges posed by the coronavirus crisis.
“Following a review of our structure as part of ongoing efforts to improve efficiency, a number of our colleagues will unfortunately be leaving Titan," said Squirrell.
"The way the Titan team has pulled together, adapted to new circumstances, shown patience and understanding, and continued to give their all during the pandemic has made me immensely proud to lead this business and the incredible people that underpin it."
Squirrell added: "We are a close knit team and will all miss our colleagues who are leaving the business. I would like to thank them for their valuable contribution and wish them all the best for the future.”
