Case scenarios

You have been called in to advise on three different legal scenarios for Fieldings Inc. which is a medium sized tech company. For each scenario, please identify: all legal issues advise the organization how to proceed discuss the implications for their business if they do not follow your sage advice. 1) Kris and Anusha were both senior employees of Fieldings Inc. Kris had signed an employment agreement when he started. Later into his role, Fieldings Inc. presented a new agreement with more stringent non-competition and non-solicitation covenants for Kris to sign, which he did. There were no new benefits given to Kris for signing, just more conditions on his employment; Kris felt obligated to sign, although he did not want to. When Anusha started, she signed the same employment agreement that Kris signed. Kris and Anusha soon after resigned from their roles with no notice, and immediately worked for a competitor corporation, Tech 101 Inc. who had been luring them to leave. The owners of Fieldings Inc. were very frustrated by this. Please advise them on how to deal with Kris and Anusha and any differences that might exist. 2) Debra was sixty nine years old, and was not working as efficiently as when she first started thirty years ago. Fieldings Inc. grew frustrated and took Debra off her Specialist duties and assigned her clerk duties instead without her consent. When this happened, a few other employees began to tease Debra and dump all of their work on her and demand unreasonable deadlines for completion. When Debra reported it to Management; they did nothing to help solve the issue of restoring her old duties, or investigating the teasing. Debra felt as though she had no choice but to resign. 3) The Marketing and Communications Manager, Javier entered into a contract to have digital billboards created across Canada to promote Fieldings Inc. with a $$$ Promotions Inc. Javier had approval from the owners to spend $100,000 on this project. When the billboards were released, they were not what Javier expected - they were based on early conversations that had changed during the contract negotiations. As well, the invoice for $$$ Promotions Inc. was for $250,000. No formal contract was signed however, there were several emails that went back and forth. Fieldings Inc. does not want to pay for the billboards. $$$ Promotions Inc. are refusing to change the content.
