(a) No compensation shall be payable for total or partial incapacity under the provisions of this chapter on account of any injury which does not incapacitate the injured employee for a period of more than three days from earning full wages at his customary employment. If the incapacity continues for a period of more than three days but less than seven days, compensation shall begin at the expiration of the first three days of total or partial incapacity. If the incapacity continues for a period of seven days, compensation shall begin from the date of the injury. (b) The injured employee shall be entitled to full wages for the entire day of the injury and that day shall not be counted as a day of incapacity. (c) If the employee is entitled to receive compensation for permanent disability to an injured member in accordance with the provisions of subsection (b) of section 31-308, the compensation shall be paid to him beginning not later than thirty days following the date of the maximum improvement of the member or members and, if the compensation payments are not so paid, the employer shall, in addition to the compensation rate, pay interest at the rate of ten per cent per annum on such sum or sums from the date of maximum improvement. The employer shall ascertain at least monthly whether employees are entitled to compensation because of a loss of wages as a result of the injury and, if there is a loss of wages, shall pay the compensation. The chairperson of the Workers' Compensation Commission shall adopt regulations, in accordance with the provisions of chapter 54, for the purpose of assuring prompt payment by the employer or his insurance carrier.
