Another instance can be seen in the UK where the North Wexford Society for Prevention of Cruelty to Animals (NWSPCA) in the UK made a statement for companies to be "more sympathetic to employees" who have pets. The Society's chairman believes that employees who have a pet that pass away should be allowed to take mandatory leave from work. Taking the essential break could give people time to grieve properly for their pet in private. He further points out that it would essentially increase an employees sense of loyalty to the company as they are understanding about their situation.
At our veterinary clinic we have witnessed on a regular basis the reactions of people when they have just lost a much loved. Some clients could not even function properly and were in complete shock from the news. In a few cases, we had to ring another family member to come pick them up. This does not mean that everyone would have such a grave emotional reaction. Other clients coped better and try to get their mind off it by preferring to return to work immediately. Regardless of how a person chooses to respond to the death of a much loved pet, it would make sense for an employer to be more sympathetic to the situation.
As the number of households that have pets increase, undoubtedly employers would become more open to the idea of leave for pet owners. Even your boss would probably have a pet they dote on in their own household! People taking time off for this sort of occurrence may be thought of as a drain on the economy, but it may just what they need to recover quicker and be more a hard working employee once more.
