The weather has a major impact on the life and work of mailmen. It can pose risks to their safety and affect the speed of their delivery. Rain, snow, and ice can cause slippery roads and sidewalks, making it difficult to navigate while carrying a heavy package. Sun and heat can make the job more tiring and uncomfortable. Heavy winds can make it difficult to deliver mail and can cause damage to mailboxes and packages. Mailmen must also be aware of lightning, thunderstorms, and other hazardous weather conditions.
