sub is bottom of the totem pole, has maybe 2 years in. But he is filling in for his reg because of medical issues. Works 3-4 days a week, calls in sick on days like today. Im the senior sub in the office, yet somehow i still get to work his crappy days. In about a year, he will be my sub, as the reg on that route is retiring. Wish i could train them like the old days..
