Employee Retention Agreements are used to define and formalize the agreement between an employer and an employee. There are several variations of employee/employer agreements and this type is used to address situations wherein a level of uncertainty (shift in management or a buyout) might make a good trained employee look for a new opportunity.
An employee retention agreement enables an employer to retain their investment in a valuable employee by outlining details mutually beneficial to both parties such as the period of time the employee will remain at the company as well as other details which can range from a guaranteed bonus to a commission percentage or other benefits.
