What happened to trade unions in 1980 and 1970?

In the 1970s and 1980s, trade unions faced significant challenges and transformations. The 1970s saw a surge in union membership and activism, particularly in response to economic issues like inflation and unemployment, leading to notable strikes and collective bargaining efforts. However, by the 1980s, many unions experienced decline due to economic shifts, globalization, and political opposition, notably under leaders like U.S. President Ronald Reagan, who took a hard stance against organized labor, exemplified by the PATCO strike in 1981. This era marked a turning point, with many unions struggling to maintain influence and membership amidst changing economic and political landscapes.
