Since 1940, the period changed to 6 years. Therefore, a claim from a Title 5 employee must be received by the agency or OPM within 6 years after the claim accrues. The term compensable only means to make payment or reparation. It does not solely mean to make payment in the form of overtime money or compensatory time. As an example, Tab 11, has to do with Training as Hours of Work.
Time spent in training during normal working hours is considered hours of work.
It does not mean you pay an employee overtime or comp. If employees want to work compensatory time and the supervisor agrees, then supervisor can approve comp. Yes, this could lead to a problem. Although the same cautionary language is not found in 550.144 for exempt employees, management should not interfere with the employee's right to elect compensatory time. The multiple time zone issue was discussed in Comptroller General Decision B-229355, dated November 22, 1988.
