Asda the best company.
Workers at the firm were questioned in a Fortune magazine exercise to find employers offering a 'great workplace, distinctive culture and a clear social mission'.
Fortune said there was more than a 'warm and fuzzy' atmosphere at Asda adding, 'Employees have well-defined ways to move up from entry-level jobs.'
The magazine also highlighted 'colleague circles' in every Asda store which served as sounding boards for grievances and ideas for improvement.
Asda, owned by US giant Wal-Mart, employs 125,000 workers at 265 stores in this country.
Asda said its working practices included a scheme allowing parents time off to take children to their first day at school, up to a week off to help with the birth of a new grandchild, job sharing, career breaks, adoption leave and so-called Benidorm leave for over-50s wanting to take up to three months off in the winter.
Workers having fertility treatment are given paid leave.
David Smith, Asda's People Director said, 'We always try and stay one step ahead of the game.'
