The document discusses strikes and lockouts under Indian labor law. It defines a strike as a cessation of work by employees acting in combination for demands related to employment. A lockout is defined as an employer temporarily closing a workplace or suspending work. There are various types of strikes like stay-away and sit-down strikes. A strike becomes illegal if certain notice periods are not followed. Similarly, lockouts must follow certain rules or become illegal. The roles of HR managers in preventing strikes include maintaining good policies and communication, as well as negotiating to resolve strikes.
