You can be suspended for just about anything. In most states employment arrangements are what is known as "at will".  Generally this means that an employer can hire or fire someone for any reason or no reason whatsoever, as well has increase/decrease salary/hours, promote/demote, and generally impose requirements as they see fit.  You in turn can work for an employer, or not, your choice. Exceptions to the above would be if there is a stated company policy contrary to the way in which your situation was handled, or there is a union/employment agreement that does not allow for such action, or this situation has arisen due to some type of discrimination (i.e., for reasons due to your race, religion, age, disability, sex, national origin).  Unless one of these applies, your employer's action did not violate the law.
