Answer:
fixed-interval
Explanation:
Fixed interval schedule of monitoring by Supervisors in a workplace is the used of a fixed time to evaluate the activities that are happening in an organisation.
For example in this case Branson is at the same time every hour he opens the door to see what his employees are doing.
However they only work hard when the door opens and relax afterwards.
The main disadvantage of fixed interval schedule is that responses are high at the point of monitoring and declines afterwards.
The best option will be to use a random schedule that way the respondents will always be doing their best in case they are being monitored
