How to hire " at will " employees
Check your state law.
In the united states , 49 out of 50 states presume that an employee is an " at will " employee. The one exception is montana.
If you work in any state but montana, then you can assume that a court would consider all employees " at will " unless you modify the " at will " status with a contract. Typically, employment contracts are express, written contracts.
