Busy repair schedule

My girlfriend is 6 months pregnant, and she is due for a sonogram and check up today. I really wanted to join her at the doctor, but I’m too busy at work. I requested the afternoon free, but our schedule is too packed to have the afternoon off. My partner and I have 7 HVAC repairs scheduled for the day. Normally, we only have four or five calls. Everyone is having HVAC trouble at the same time, and that means working a long 12-hour day. My partner and I have been working in the HVAC industry for the past 6 years. We graduated from HVAC technical school at the same time, and received job offers from the same large company. My partner and I have been working together since the beginning, and we have great repair times. My partner and I usually spend most of the day working on HVAC repair jobs. Most of the HVAC installation jobs are completed by an outside contractor. The HVAC installation jobs can take most of the day. Since we have a small crew, it’s better to subcontract these installation jobs to a different company. My partner and I handle HVAC repairs most of the day, while a different company handles all of our installation jobs. I was hoping for a slow day, so I could join my girlfriend at the doctor. Unfortunately, I guess I’ll have to wait to see the small black and white picture. It doesn’t look like I am going to be done with HVAC repair calls anytime soon. I hope my girlfriend will understand.
