Being an at-will employee means your employer can terminate your employment at any time, and does not need good cause to do so. In most jurisdictions, there is a legal presumption that you are an at-will employee unless you can show evidence to the contrary. Such evidence may include an employer’s written policies or verbal statements regarding your job security. Note that while an employer need not show good cause to fire an at-will employee, those workers are still protected by laws prohibiting discrimination and harassment.
