The year I decided to cut back on assignments is the year that the district says they are extremely short of subs. They blame the recovering economy for subs leaving the sub pool to return to full time, better paying jobs.
That meant that the "roving sub" status they had me on last month had me traveling and working more than I wanted so I did not re-up for the rest of the school year.
The district is "strongly suggesting" to teachers, not take any discretionary days off for the rest of the year unless they personally arrange for substitute coverage.
Judging by the number of emails I am getting, I'm pretty sure I could work almost every school day for the rest of the school year if I wanted.
Things are so dire that I have already booked an assignment for the last Friday of the school year in June.
