There is, however, one matter we have reserved for the last, because it is one of the two or three points about which the immediate contest before us is to rage. That is the case of individual discharge. It is elementary that just as an employee may leave with cause or without cause, so an employer may discharge without cause or with cause, nor is he bound to state his reasons, and certain statutes requiring him to do so with the object of avoiding a blacklist have been declared unconstitutional in Southern States. But organized labor is naturally very desirous of resenting the discharge of anybody for no other reason than that of being a union man. In fact it is not too much to say that this, with the legalization of the boycott, are the two great demands the unions are now making upon society. Therefore, statutes have been passed in many States making it unlawful for the employer to make it a condition of employment that the employee should not be a member of a union; or to discharge a person for the reason that he is a member of a union. And closely connected with this is the combination of union employees to force an employer to discharge a man because he is not a member of a union. This last will come logically under the next chapter covering combinations and is not yet the subject of any statute. Now the difficulty of these statutes, about the discharge of union labor, is that it is almost impossible to go into the motive; a man is discharged "for the good of the service." It is easy, of course, to provide that there should be no written or definite contract on the matter; but it is not easy to punish or prohibit the discharge itself without such contract. Such legislation has, however, been universally held unconstitutional, so that at present this must be the final word on the subject. The right of the employer to employ whom he likes and to discharge whom he likes and make a preference, if he choose, either for union or non-union labor, is one which cannot be taken away from him by legislation, according to decisions of the Supreme Courts of Missouri, New York, and the United States. Therefore, as the matter at present stands, the constitutions, State and Federal, must be amended if that cardinal right of trade and labor is to be interfered with. In closing it may be wise to run over the actual labor laws passed in the States during the last twenty years, mentioning the more important lines of legislation so as to show the general tendency.
