Today is one of my scheduled days off. This morning I was woken up by my phone. I got a call from NOVA asking me to work an overtime shift in Fujinomiya.

Numazu to Fujinomiya (thanks Google Maps)
I was totally caught off guard by the overtime request and still half asleep so I almost said yes. Somewhere in the back of my brain an alarm bell started ringing, reminding me that Fujinomiya was about a 40 minute train ride away and that the school was full of group kids classes. I like extra money, but I needed the day off more so I declined and went back to sleep for a few more hours. I found out later that the overtime shift came available due to a teacher calling in sick the day after a party.
One of the annoying things about being a conversational English teacher is that everyone has different days off. This allows the branch to be open 7 days a week, but guarantees that no matter which night of the week there is a party, someone is going to have to work the next day.
Drinking is part of the English teacher culture – many of the fun events after work involve alcohol in some way. In time you either learn how to moderate your intake on work nights or how to work through a hangover. Calling in sick the next day is universally considered to be bad form among teachers, and will make you very unpopular with managers and branch staff (as I learned first hand).
It should be noted that “not drinking” is always an option, but then you risk truly hearing how bad everyone is at karaoke. I don’t recommend this at all.
If you are teaching English overseas, always make sure you can get into the office the next day!
