The labor of a human being is not a commodity or article of commerce, and the right to enter into the relation of employer and employee or to change that relation except in violation of contract is a legal right. In all cases involving the violation of the contract of employment, either by the employee or employer where no irreparable damage is about to be done to the property, personal rights or property rights of either, no injunction shall be granted, but the parties shall be left to their remedy at law.
