What type of foot attire is discouraged for employees?

Flip-flops are discouraged for employees primarily due to safety and practicality concerns. In a work environment, especially one involving physical activities like guiding tours in a cave, footwear needs to provide adequate support and protection. Flip-flops lack the support necessary for stability and can easily come off or cause slips and falls on uneven or slippery surfaces, which are common in caves.

Additionally, flip-flops do not offer any protection for the feet from hazards such as falling rocks, sharp objects, or water puddles, which can be present in such environments. For these reasons, more supportive and protective footwear is deemed appropriate for ensuring the safety and comfort of employees while they perform their duties.
