Explanation: Since at-will employment is a term that is used in the U.S employment law, the employer has the freedom to fire an employee at any given time and has no obligation to give an explanation for it, as long as the reason is not illegal - that reason being based on religion or race. This law also includes that, if somebody gets hired at-will, they can also leave their job without giving any explanation. This example makes posting something like this legal but risky when it comes to employee keeping their job.
