The principles discussed in Secs. 778.220 and 778.221 are also
applied with respect to certain types of extra payments which are
similar to call-back pay, such as: (a) Extra payments made to employees,
on infrequent and sporadic occasions, for failure to give the employee
sufficient notice to report for work on regular days of rest or during
hours outside of his regular work schedule; and (b) extra payments made,
on infrequent and sporadic occasions, solely because the employee has
been called back to work before the expiration of a specified number of
hours between shifts or tours of duty, sometimes referred to as a ``rest
period.'' The extra payment, over and above the employee's earnings for
the hours actually worked at his applicable rate (straight time or
overtime, as the case may be), is considered as a payment that is not
made for hours worked.
