A&R Employment Agreement [Member]        
Subsequent Event [Line Items]        
Deferred compensation arrangements, overall, description       The A&R Employment Agreement states that in each year of employment, including 2021, Mr. Croskrey will receive a long term incentive award, of which 50% shall be in the form of performance stock awards that vest upon satisfaction of performance targets to be established by the Board of Directors for each such year and 50% shall be in the form of stock options that vest over time. If shares of common stock are not available to settle the awards as they come due, we will settle them in cash.The A&R Employment Agreement also modified all stock compensation instruments previously granted to Mr. Croskrey, which stipulated that if shares of common stock are not available to settle the awards as they come due, we will settle them in cash. We previously awarded Mr. Croskrey approximately 1.2 million options with an exercise price of $24.20 that are contingently granted upon on shareholder approval of an increase in the number of shares issuable under the 2020 Incentive Plan, which has not occurred, and therefore these awards not were reflected in our consolidated financial statements. The liability for these options will be marked to market each period end, with the income statement effect of such revaluations prorated through February 2024 and included in stock compensation expense reported within selling, general and administrative expense.The A&R Employment Agreement ends on December 31, 2024, unless earlier terminated in accordance with its terms.
