Question: in terms of non verbal communications explain why workers should wear uniforms? 

Answer: Uniforms convey many non-verbal meanings.  \n\nNamely, they are the primary way customers identify employees.  When you enter a store, for example, and need help, you're likely to turn to the person wearing the proper colors/uniform.\n\nIn addition, uniforms show solidarity with the employer.  In other words, they indicate the employee's willingness to submit her will/individuality to the needs/desires/requests of her employer.\n\nUniforms also heighten customer awareness of the corporate logo (since every uniform has it) and decrease the need for employer's monitoring of employees' dress.
