job, except for employees who are in the top 10% of highest paid and the employer can argue refusal "is necessary to prevent substantial and grievous economic injury to the operations of the employer." Employees or the Secretary of Labor can bring enforcement actions, but there is no right to a jury for reinstatement claims. Employees can seek damages for lost wages and benefits, or the cost of child care, plus an equal amount of liquidated damages unless an employer can show it acted in good faith and reasonable cause to believe it was not breaking the law. There is a two-year limit on bringing claims, or three years for willful violations. Despite the lack of rights to leave, there is no right to free child care or day care. This has encouraged several proposals to create a public system of free child care, or for the government to subsize parents' costs. Pensions In the early 20th century, the possibility of having a "retirement" became real as people lived longer, and believed the elderly should not have to work or rely on charity until they died. The law maintains an income in retirement in three ways (1) through a public social security program created by the Social Security Act of 1935, (2) occupational pensions managed through the employment relationship, and (3) private pensions or life insurance that individuals buy themselves. At work, most occupational pension schemes originally resulted from collective bargaining during the 1920s and 1930s. Unions usually bargained for employers across a sector to pool funds, so that employees could keep their pensions if they moved jobs. Multi-employer retirement plans, set up by collective agreement became known as "Taft-Hartley plans" after the Taft-Hartley Act of 1947 required joint management of funds by employees and employers. Many employers also voluntarily choose to provide pensions. For example, the pension for professors, now called TIAA, was established on the initiative of Andrew Carnegie in 1918 with the express requirement for participants to have voting rights for the plan trustees. These could be collective and defined benefit schemes: a percentage of one's income (e.g. 67%) is replaced for retirement, however long the person lives. But more recently more employers have only provided individual "401(k)" plans. These are named after the Internal Revenue Code §401(k), which allows employers and employees to pay no tax on money that is saved in the fund, until an
