Cash and Cash Equivalents [Abstract]
Restricted Cash	Restricted Cash At December 31, 2018, our cash and cash equivalents included $5.1 million held in a restricted cash account on deposit with our insurance carrier. This account served as collateral, in place of an irrevocable stand-by letter of credit, to provide financial assurance that we will fulfill our obligations with respect to cash requirements associated with our workers' compensation self-insurance. This cash was to remain on deposit with the carrier until all claims have been paid or we provided a letter of credit in lieu of the cash deposit. At December 31, 2019, no deposits were held in a restricted cash account as we provided a letter of credit in lieu of the cash deposit.

The entire disclosure for cash and cash equivalent footnotes, which may include the types of deposits and money market instruments, applicable carrying amounts, restricted amounts and compensating balance arrangements. Cash and equivalents include: (1) currency on hand (2) demand deposits with banks or financial institutions (3) other kinds of accounts that have the general characteristics of demand deposits (4) short-term, highly liquid investments that are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates. Generally, only investments maturing within three months from the date of acquisition qualify.
