9.4. An employee’s salary or wages for the period established in paragraph b of section 9.1 correspond to the salary or wages payable to the employee for his first pay period after a reduction:
(a) entirely included in the established period;
(b) during which the employee works the time provided for in his contract of lease and hire of personal services or in accordance with the requirements of his office; and
(c) for which the employee receives the full salary prescribed for that pay period.
The salary or wages prescribed in the first paragraph must be adjusted to a yearly basis by multiplying the figure by the number of times the employee’s pay period is contained in the period established in paragraph b of section 9.1.
