Answer:
They have work that is characterized by fragmentation, brevity, and variety.
Step-by-step explanation:
Hentry Mintzberg, a famous American non-fiction author, wrote in one of his books on management about the roles of managers. In it, he described their work as being fragmented, short, and varied.
Fragmented means that they often have to stop what they're doing in order to jump into something else that may be more urgent. Brevity refers to the fact that they usually do things quickly because of how many obligations they have. Variety refers to the various types of work they have to perform within their obligations.
