Team unity results from everybody wearing the same uniform. This promotes fairness and equality in the workplace; a factor which is important to most employees.
With fairness and equality in the workplace being important, uniforms take the pressure off employees to dress in a certain way. Not having to stress about buying a certain quality of clothing or PPE can be a huge relief for some.
Working in a team-oriented environment is a positive motivator and benefits both employers and employees. A standard uniform promotes equality even among individuals with different levels of experience. Your Catering staff will take pride in themselves as a result of looking and feeling good, which will be reflected in their standard of work. They will shine with pride just as brightly as the cutlery they polish.
