What is the major reason unions are on the decline in the us?

Unions often seem irrelevant. In good times, workers don’t need unions to secure increases in wages and benefits because everybody profits from economic prosperity. Unions have a poor public image as being bloated, inefficient and often downright corrupt. Stories about labor racketeering, mob influence and trials of union officials for embezzlement and bribery are common fare on the evening news. Workers are often “out of sync” with union politics. The labor movement is perceived as being a vassal the Democratic Party and a champion of liberal causes. Most Americans now turn to government, not unions, for basic protections. Workers rely on the government for pensions, healthcare, protection against discrimination and a whole variety of other benefits that were formerly provided exclusively by unions.
