I work for a large, Fortune 500 company as a software developer. One of the pinch points is that we need to be 'on call' for one week at a time on a rotation and this might include Sundays.
We are not paid extra for being on call and the work can be done remotely at home. There is not always work to be done while 'on call'; it's just if there is a severity 2 bug then you will need to be available to investigate the bug. I still attend mass on those days. It's rare that this occurs on Sundays, because most of our customers do not work on Sundays.
It would be very inconvenient to change my rotation to exclude Sundays and given that it's rare to be called on Sundays, I'm wondering if this is really an issue from a Catholic perspective?
