A uniform such as a t-shirt with the company's logo make it easier for customers or clients to distinguish workers in a crowd. Having workers wear uniforms can improve customer service, since it helps customers determine who's there to help them. Having workers in uniforms can also level the playing field for all employees. In some businesses, employees may not be able to afford professional, work-worthy clothing. When that's the case, uniforms provide a level of equality, helping all employees feel comfortable and confident. It can also cut down on competition or cattiness in regard to what other employees are wearing, leaving more room for the actual work at hand.
