If you are wondering how to reward your staff this year, one growing trend seems to be to give them Prize Bonds. The bonds, which can be bought for a minimum of £10, can be purchased from post offices. Employees then have the option of holding on to them with the hope of becoming a prize winner in the bumper draws or cashing them in tax free. Alternatively, companies can buy Prize Bonds for a staff social fund, where employees benefit from the prizes, which are also tax free.
