Whitbread is preparing to cut an estimated 250 management jobs from its restaurant business as part of a reorganisation.
The company said it wanted to bring its structure "in line with industry norms".
The move is understood to be unrelated to the recently announced demerger of the Premier Inn and Costa brands.
The coffee giant will become a separate entity to the Premier Inn brand within two years, following demands from the company's largest investor, Elliott Advisers.
Commenting on the news of job cuts within the restaurant business, a Whitbread spokesperson said: "We're proposing to simplify the management teams in our restaurants' business, which will bring our structure in line with industry norms.
"By doing so we will create a more efficient and effective organisation, and ensure we continue to deliver our ambitious growth plans. Regrettably however, the proposed changes would result in a number of managers leaving the business.
"We are consulting directly with the individuals impacted and will endeavour to find them alternative positions wherever possible. Over the next year, our Premier Inn and Restaurants' business will create 1700 new jobs across the UK by investing around £300 million in dozens of new hotel and restaurant openings."
