Construction, modernization, and repair work is paid 2x the standard rate for overtime. Scheduled service work overtime is paid 1.5x the standard rate. Service calls on overtime are paid 1.7x the standard rate. Service calls on Sunday are paid 2x the standard rate. The real question here is, do you want to do the overtime?
