9.3. An employee’s salary or wages for the period established in paragraph a of section 9.1 correspond to the salary or wages paid to the employee for his last pay period before a reduction:
(a) entirely included in the established period;
(b) during which the employee worked 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 has received the full salary or wages 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 a of section 9.1.
