Two senior members of staff have been suspended at Tom Kitchin's restaurant group following allegations of "unacceptable behaviour".
The Times has reported accusations by former staff of assault, harassment and bullying while working at the group's restaurants. One chef claimed he had developed mental health problems following his experiences. The report followed anonymous claims made via an Instagram account.
Kitchin Group managing director Peter Southcott said: "Following allegations of unacceptable behaviour, two senior members of staff have been suspended whilst these claims are fully and independently investigated. We will not hesitate to take whatever action may be necessary."
Tom Kitchin said: "Top kitchens the world over can be high-pressure, frenetic and challenging environments, where emotions often run high. However, the exacting standards of our food and service must be matched by the standards of behaviour in our kitchens and wider operations.
"In the last few years, the feedback from our team members underlines the significant strides we've taken to improve what had often been a traditional culture in our kitchens, but we have more to do. I'm immensely proud of my colleagues at the Kitchin Group and where we have fallen short, we will address it and remedy it. That will be our clear priority in the weeks, months and years ahead."
The Edinburgh-based group includes the Michelin-starred Kitchin restaurant, the Bonnie Badger, the Scran & Scallie and Southside Scran.
