What Workwear items make up a uniform ?
Most uniforms consist of a range of items from boots to t-shirts. Starting at the feet, many companies require their employees to wear some form of protective footwear depending on the environment, steel or composite toe cap boots/shoes are usually worn. Next would be a pair of work trousers, shorts or a skirt, with anything from a formal shirt to a t-shirt for the upper body. Although each workplace is different the overall uniform design is relatively the same, excluding PPE based items such as hard hats, safety footwear and gloves, these items really depend on the environment.
Uniforms do not need to be provided by the employer, however, items that are considered PPE must be provided at no cost to the employee. This can be found in Section 9 of Health and Safety at Work etc Act 1974, "No employer shall levy or permit to be levied on any employee of his any charge in respect of anything done or provided in pursuance of any specific requirement of the relevant statutory provisions". – Source HSE.
