The phrase "most office" can be substituted with several synonyms, depending on the context. Often, the term "majority of the office" or "bulk of the office" is used to refer to the largest group of employees within a workplace. Alternatively, one might use "predominant" or "dominant" to describe the most influential or prevalent individuals in the office. In certain situations, the term "core team" or "key personnel" might be more fitting, as they represent the essential employees responsible for driving the business. Ultimately, the choice of synonym depends on the desired emphasis and the specific setting in which the word is being used.
