Indiana Code Title 22. Labor and Safety § 22-6-2-15

Sec. 15. Nothing in this chapter shall be construed to require an individual employee to render labor or service without his consent, or to make illegal the quitting of his labor or service or the withdrawal from his place of employment unless done in concert or by agreement with others.  No court shall have power to issue any process to compel an individual employee to render labor or service or to remain at his place of employment without his consent.  It is the intent of this chapter only to forbid employees to leave their employment in concert or to cause a work slowdown or stoppage in concert and to forbid an employer to lock out his employees in any case where the resultant interruption of public service would cause severe hardship to a substantial number of persons.
