Employment involves an employer hiring an employee under an employment contract to perform specific duties in exchange for compensation. Development is a process of gradual advancement through progressive changes towards achieving goals. A license gives permission, such as allowing the use of intellectual property under certain terms to avoid infringement claims. A non-disclosure agreement outlines confidential information that parties wish to share privately without third party access. Collaboration is working together towards shared goals, allowing teams to obtain more resources when facing competitive challenges.
