On October 23, 1992, while the Boston Harbor case was still on trial, President George H.W. Bush signed Executive Order 12818 prohibiting federal authorities from carrying out union work exclusively for construction projects.  Bush`s ordinance prohibiting the use of LTCs in federal construction projects.  The Clinton administration rescinded that order when President Bill Clinton issued Executive Order 12836 in February 1993, shortly after taking office.  This contract allowed federal authorities to finance construction projects for which contractors needed a PLA.  A month later, the U.S. Supreme Court unanimously upheld the implementation of public projects agreements in the Boston Harbor Cleanup case.  The Supreme Court held that if the government was in the role of a regulatory authority, it was not in a position to require the use of PLA in accordant to the principles of pre-emption of labour law, but it could choose to do so as a market player without being anticipated by the National Labor Relations Act.  The Court did not consider whether state-imposed APAs were legal under the federal or federal competition laws. The decision led to increased use of PTPAs in public construction projects in the United States Agreements have been in place in the United States since the 1930s and were first debated in the 1980s for their use in publicly funded projects. In these cases, the public authorities have made the signing of ATPs a prerequisite for working on taxpayer-funded projects.
This type of ALP, known as a government-mandated ALP, is different from a PLA that is voluntarily carried out by public or private works contractors – as NNRA allows – and a PLA that has been mandated by a private agency for a privately funded construction project. Executive orders adopted since 1992 have had an impact on the use of mandatory PLAs for federal construction projects, and the last order issued by President Barack Obama in February 2009 encourages their use by federal authorities. The use of PLA is rejected by a number of groups that claim that the agreements discriminate 30/10 contractors and do not improve efficiency or reduce the costs of construction projects. THE PTPA studies have mixed results, with some studies concluding that PTPAs have a positive effect, while others find that agreements can increase costs and have a negative impact on contractors and non-unionized workers. Government-mandated AEPs have been the subject of much discussion, particularly for publicly funded projects.  The implementation of project work contracts is supported by construction unions and by some political figures who say that it is necessary to ensure that large, complex projects are completed on time and on time.  In the view of those who support the use of such agreements, THE PLA allows project owners to control costs and ensure that there is no disruption to the construction plan, for example. B by strikes.  In particular, TPC proponents refer to the inclusion in the agreement of clauses that agree to create committees to address labour management issues that deal with planning, quality control, health and safety and productivity issues during the project.  They also note that the AEPs ensure that the recruited workforce is trained and of high quality.
 The use of PLA in large private projects such as the construction of gillette Stadium of the New England Patriots is cited as an example of how PLA project owners are helping to meet tight deadlines, according to fans.  In addition to the reported benefits to project owners, PLA proponents also argue that the use of PLA has a positive impact on local communities by setting targets for local hiring and education provision.
