We had a controller who wanted to use holiday leave on July 4th. They had to come in for staffing requirements in the morning but they could have been cut loose in the evening. They told the sup they wanted to take holiday for the rest of the day and our sup denied it so they could be on ground while our sole trainee who has over 20 years of experience and is 6 months from retirement could work local with zero traffic for NTI. Sup ended up getting the controller off position 15 minutes before their regularly scheduled time to leave, basically making them work a full 8 hours, then signed the person out 15 minutes early on annual leave instead of holiday. The controller saw that and thought it would be stupid to sit around since the leave was already charged so they left, and when they confronted the sup about it the next day the sup got all defensive. “Well you said you wanted to leave early, and I saw you drive out the gate so you obviously used it”. Yeah, because YOU went ahead and charged it and signed them out without their permission. Then the sup tried to guilt the controller into just eating the leave - “do you know how much paperwork I’d have to do to get that time back for you? It’s just 15 minutes, are you sure you can’t let it go?” But don’t worry, that sup is becoming our ATM next month so it’ll only go up from here ?
