My job preparing children for a lifetime of disrespect at work

I work at a school my school that introduced these repetitive computer lessons that now take up a good third if not more of the school day . Some of the kids unsurprisingly hate them and will do anything to get out of them. So now we apparently can’t let them get water or go to the bathroom during computer time until we meet our class quota of minutes . These are very young children I’m so angry .
