Abstract: A break management system automatically calculates employee break schedules for a large number of employees according to both legal requirements as well as business operating needs. Businesses may enter preference rules regarding the timing of breaks relative to other breaks and relative to other employees and work positions. The break management system provides a user interface with required breaks, suggested break windows, and break timing requirements for each employee and allows a shift leader to manage breaks from the interface.

Abstract: Systems and methods for sender profile and/or recipient profile disambiguation and/or confirmation are disclosed. In instances where a sender profile is not indicated by a user sending a communication from a communal device, heuristic data may be utilized to infer the sender profile. Similar heuristic data may also be used when selection of the sender profile is associated with a low confidence level. Heuristic data may also be used to infer the recipient profile when the user does not indicate the recipient profile or when selection of the recipient profile is associated with a low confidence. Various confirmations may result from the sender and recipient profile disambiguation.
