According the the new dress code issued by Southampton City Council, women are prohibited from wearing mini-skirts to work and employees, who come in contact with customers have been asked to dress more professionally.
People involved in "customer-facing roles" have been told to look more professional "in a way that shows respect to children and families", the Daily Mail reported.
Four-hundred staff in the children"s services department received a memo telling them they should dress respectfully, the report, published on Jul 31, added.
The memo said that women wearing mini-skirts can be sent home.
While women can wear skirts of reasonably length or trousers, men have been advised to wear collared or polo shirts, cotton trousers such as khakis or chinos with a belt, and 'dress shoes".
"Please try to dress smartly and thoughtfully, in line with other professionals you come across in your day-to-day work, and in a way that shows respect to children and families," the memo leaked on e-mail read.
Workers' unions have threatened to protest against the dress code.
