The relationships among employers and employees are the subject of a wide variety of federal and state laws. These laws govern almost every part of the relationship, beginning before the job starts and going until years after the job has ended. There are complicated issues with employment applications, interview questions, employment contracts, ownership agreements, wages, hours, benefits, health insurance, leave time, discrimination, harassment, retaliation, severance pay, separation agreements, post-employment confidentiality, and non-compete agreements. For all of these issues, the rights and duties of employers, employees, and co-workers vary depending on which laws apply. Whether or not a law or set of laws applies depends in turn upon the facts of each case: how long the employee has been employed, the number of employees employed, the age of the claim, the employer's business, and the employee's job duties, to name a few.
