While I can provide information about labor laws, my responses are based on pre-existing knowledge and not real-time updates.

Therefore, it is important to consider that the context you are referring to might play a key role in identifying the most significant labor laws enacted this year. If your question pertains to a specific country or region, please mention it so that I can provide a more accurate response.
