Multiemployer Plans [Line Items]
Multiemployer plans general descriptiion	Sysco contributes to several multiemployer defined benefit pension plans in the U.S. and Canada based on obligations arising under collective bargaining agreements covering union-represented employees. Sysco does not directly manage these multiemployer plans, which are generally managed by boards of trustees, half of whom are appointed by the unions and the other half by other employers contributing to the plan. Approximately 10% of Sysco's current employees are participants in such multiemployer plans as of June 28, 2014. The risks of participating in these multiemployer plans are different from single-employer plans in the following aspects:Assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers.If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers.If Sysco chooses to stop participating in some of its multiemployer plans, Sysco may be required to pay those plans an amount based on the underfunded status of the plan, referred to as a withdrawal liability.Based upon the information available from plan administrators, management believes that several of these multiemployer plans are underfunded. In addition, pension-related legislation in the U.S. requires underfunded pension plans to improve their funding ratios within prescribed intervals based on the level of their underfunding. As a result, Sysco expects its contributions to these plans to increase in the future. In addition, if a U.S. multiemployer defined benefit plan fails to satisfy certain minimum funding requirements, the Internal Revenue Service (IRS) may impose a nondeductible excise tax of 5% on the amount of the accumulated funding deficiency for those employers contributing to the fund.
