In that case the employer should take the employee to court assuming the meritless case does not get thrown out. There is nothing to "settle" with an at will employee. Is there any sucessful case history of this? Again an offer letter is not a contract. After you start working your employer can change the terms of your employment, whether it is a month or a year later makes no legal difference for an at will employee-employer situation. Similarly you are free to quit your job after a month or a year without being sued by your former employer in either case. At will employment means the terms of employment are continuously negotiable. However, I believe in some US jurisdictions, if your employer cuts your pay or requires you to work in a new location you may be eligible for unemployment compensation in some cases if you quit. That is about it. This idea that highly paid programmers could sue their employers if they require them to show up at the office seems ridiculous to me. Unless you are an independent contractor you do not get to decide the terms of your employment. You are always free to quit and get another job though.
