"This is an employment-at-will state, and I can fire you for a good reason, a bad reason, or no reason at all." Technically, this is true in most states, but in effect it is a lie which employers rely on at their peril.

Suzanne Lucas of The Evil HR Lady has a post about an individual (sex not specified) whose employer offered him/her a different position in the company. When the employee declined the position, his/her "voluntary resignation" was demanded. In other words, the boss had tried to get rid of this employee by way of a transfer, and when that failed, forced the employee's resignation. According to the employee, he/she had never been warned of any job-related issues.

Suzanne prefaced her recommendations by pointing out that such a termination, while unfair, was perfectly legal in an employment-at-will state.
