Work

I have additional work responsibilites this new year at school. Been given 2 extra classes to teach. My co-curriculum duties have increased too. Okay, I must look at it positively. I must have been responsible and that is why I am given more? The human part of me wants to compare with other colleagues I notice they did not receive the same fate as me.
I will resolve to do my best at work and look at the positive side.Ever been in the same situation as me?
