Most brands have their own charter. If you have franchised only one brand even if you have multiple units it would benefit you to adopt your brand’s charter. This will create alignment of purpose and communication among your team and with the brand. Every charter that I have ever seen has embraced a positive and inspiring message. So it shouldn’t be difficult to embrace the charter as your own especially because it’s likely that those messages will be in multiple brand communications such as the operations manual training materials and operational job aids. It may be confusing if you have a company charter on the wall that is different than what the employees see in the brand materials. If you feel very strongly about adding your own touch to the culture that you are creating among your team then I recommend adding only a vision or a mission statement to the brand’s charter. When you share it with the team clarify what comes from the brand that you represent and are responsible to protect and what comes from the leader(s) of the company (you). Creating that distinction will help the team understand the difference.
