Labor unions are against open shops, because an open shop is a place of employment that has voted to be represented by a union, but membership in the union is not required. Without every worker belonging to the union it is harder to negotiate with the employer.

Open shops are common in labor unions in North America. With open shops, employees have a choice whether to join the union or not. Many people think open shops are weaker than closed shops.

Labor Day is a day of rest for laborers, e.g. workers. So it would be against the principle of Labor Day, but some stores, shops and resturants DO stay open on Labor Day. Some open for shorter hours, though.

The Taft Hartley Act did prohibit the jurisdictional strikes.
A practice used by labor unions that was successful in the early 1900s was not allowing companies to hire workers who did not belong to the union. This practice became known as a closed shop.
Made unionizing lawful nationwide. Gave most workers the statutory right to join or form unions or to refrain from doing so. Prohibited specified union conduct and employer conduct during representation campaigns and contract negotiation. Outlawed the closed shop, and legalized the union shop and agency shop and open shop.
The Hartley Act, also known as the Labor Management Relations Act of 1947, amended the previous Wagner Act of 1935. It aimed to curb the power of labor unions by placing certain restrictions on their activities. It prohibited unfair labor practices by both unions and employers, allowed for the decertification of unions under certain conditions, and gave the President the power to intervene in labor disputes to prevent strikes that could harm national security.
