Accounts Receivable Financing Program [Abstract]
Former Accounts Receivable Financing Program	Pursuant to a since-terminated accounts receivable financing facility (the “ABS Facility”), USF sold, on a revolving basis, eligible receivables to a wholly owned, special purpose, bankruptcy remote subsidiary (the “Receivables Company”). While the ABS Facility was in effect, the Company consolidated the Receivables Company and, consequently, the transfer of the eligible receivables was a transaction internal to the Company and the eligible receivables held by the Receivables Company were previously not derecognized from the Company’s Consolidated Balance Sheets. Included in the Company’s accounts receivable balance as of December 28, 2019 was approximately $1.0 billion of eligible receivables held by the Receivables Company as collateral in support of amounts borrowed under the ABS Facility. On May 1, 2020, USF repaid all outstanding borrowings under the ABS Facility in full and terminated the ABS Facility, as further discussed in Note 13, Debt, and as a result, the Company's eligible receivables are no longer transferred to or held by the Receivables Company.
