The Commission is also authorized to take this type of action whenever ne­ cessary in order to eliminate or reduce serious pay inequities caused by differ­ ences in pay levels of Classification Act employees and prevailing wage em­ ployees in the same government organiz­ ation and at the same location.

The differential is not a part of basic pay, does not apply when the employee is on leave, and is not included in computing any overtime compensa­ tion to which the employee may be en­ titled. Holiday Pay Eight days are recognized as holidays by federal statute; New Year’s Day, Washington’s Birthday, Memorial or Decoration Day, Independence Day, Labor Day, Armistice Day, Thanksgiv­ ing Day, and Christmas Day. D ays or parts of days on which departments and agencies are closed by executive order are treated in the same way as statutory holidays for pay purposes. The new law provides for extra com­ pensation for working on a holiday when such holiday is not generally a workday in the federal service. A pre­ mium rate of one and one-half times the regular daily rate is established as (Continued on Page 20)
