All classified employees are entitled to visit the United States or foreign countries once in every three years, receiving in addition to their accrued leave, one year's vacation leave, allowance of actual travel time at half pay not to exceed sixty days, and return travel expenses from place of residence in the United States, or from port of embarkation in a foreign country to Manila, on the completion of two years of service after date of return. An employee entitled to thirty-five days' accrued leave per annum who visits the United States after having rendered three years of service receives a total of two hundred thirteen days' accrued leave, vacation leave, and half-pay travel time. If he postpones his visit till he has completed five years of service, he receives a total of two hundred ninety-one days' accrued leave, vacation leave and travel time. An employee entitled to thirty days' accrued leave per annum who visits the United States after three years of service receives a total of one hundred ninety-four days' leave and half-pay travel time, and if he postpones his visit until he has rendered five years of service, he receives a total of two hundred fifty-nine days' leave and travel time. It will be seen that these are very liberal allowances. An employee receiving $1200 at the end of two years of service may spend eight weeks of vacation leave visiting Japan or other surrounding countries, and at the end of an additional year's service he may visit his home in the United States with six and a third months' absence on full and half pay and with his expenses from his home to Manila payable two years after his return, and during every three years of his service he may have the same privileges. The law also provides that if an employee is wounded or injured in the performance of duty, he may have a total of six months' leave on full pay in addition to any accrued leave to his credit. Employees who have rendered satisfactory service and resign after three or more years receive in a lump sum all accrued leave due and thirty days' half salary. For example, an employee who has received $1800 per annum and has served five years without taking any leave in excess of the four weeks' vacation leave allowable annually would draw $1025 were he to resign. The school sessions amount to forty weeks per annum and the school vacations to twelve weeks per annum. [491] Teachers receive an annual salary and draw full pay during vacations as well as during school sessions. Every third year they are allowed to visit the United States or foreign countries with an allowance of sixty days' half-pay travel time in addition to the ten weeks' long vacation, and on completing two years of service after return to the islands they are entitled to their travelling expenses from place of residence in the United States to Manila or from port of embarkation in a foreign country to Manila.
