No, it should be compensated, so Management prioritises fixing issues, instead of adding new bugs
But let's align incentives. Any time spent fixing issues on-call is compensated 4-to-1. Workers may accrue compensation time, and any compensation time in excess of 20 hours is paid 10-to-1 when the employee leaves. The idea here isn't for workers to accrue and cash out comp time, but instead to give an incentive to the organization to ensure workers use their comp time.
Let's align incentives, what's hard on the worker should be hard on the owners and management.
When that's done, chill for a while, do some recruiting and education in the workplace and think about what the next realistic change ought to be.
