However logical it may sound: Make sure that there is a variety of theme and activity for each party. After all, you don't want to be predictable for your employees. As soon as the staff parties get boring, you will not achieve the desired effect. So be smart with the organization and take up the challenge with yourself, in order to create that "wow-feeling" in your staff every year. This can only be achieved with an original, thoughtful and smart idea. For example: one year a sports day, the next year a workshop, Friday drink or a surprising unique activity.
Also try to find variety in the location where the party is held. Look for a unique location! A chic restaurant, hotel, party boat or challenging assault course, just to name a few examples. An original location is half the job! Who do you invite? Here too you alternate. One year you invite the partners and the next year you celebrate the party exclusively with the staff. A family day with partners and children is also very good. As a company you show an open and committed character. This is always appreciated.
