Final answer:
Studies indicate that the average first-line manager spends no more than 10 to 12 minutes on a task before being interrupted by a request from a subordinate, a phone call, or an email.
Step-by-step explanation:
The average first-line manager spends no more than 10 to 12 minutes on a task before being interrupted. Despite the lack of a specific time mentioned in the question, various studies suggest that managers are frequently disrupted by subordinates, phone calls, or emails. This speaks to the broader concept of time management and efficiency in the workplace. To combat this, setting priorities for the following day, only responding to emails several times a day, and making a distinction between work and personal life are effective strategies. Protecting private time and not being available 24/7 can help mitigate constant interruptions. The average first-line manager is frequently interrupted while working on tasks, with no specific time given. Effective time management techniques include setting daily priorities, managing email access, and separating work from personal time.
