Claim 6:
7. A method of monitoring workers in a retail environment, comprising:
receiving video feeds from a plurality of cameras located in different regions of the retail environment and configured to capture a video feed of a respective region of the retail environment;
determining a location of the worker in the video feed, wherein determining the location of the worker in the video feed comprises identifying the worker at a first location in a video feed of a first region based on input to a worker interface and tracking the location of the identified worker from the first region including the first location to a second region including the location of the worker in the video feed of the second region, wherein tracking the location of the identified worker comprises re-identifying the worker in the video feed of the second region based on one or more of height, gender, age, gait, or uniform when the worker leaves the video feed of the first region and moving at least one camera of the plurality of cameras to maintain a field of view of the camera on the worker;
providing the video feed of the second region of the retail environment to a machine learning classifier, the machine learning classifier trained on labeled videos, to classify a sequence of images of a worker into a probability certainty of an activity being performed by the worker;
determining, based on probability certainties generated by the machine learning classifier over a period of time, an activity schedule of the worker, wherein determining the activity schedule of the worker comprises:
determining a set of activities for the location of the worker in the video feed of the second region; and
adjusting the probability certainty of the activity based on whether the activity is in the set of activities for the location of the worker in the video feed of the second region by adding an adjustment amount to the probability certainty for the activity if the activity is in the set of activities for the location and subtracting the adjustment amount if the activity is not in the set of activities for the location; and

determining labor productivity statistics based on the activity schedule.
