There will be people, who will feel it is critical important to post some pictures at 3 am and they will get stressed, if it is not working (say people preparing an event and the pictures should be online the next day).
But .. whether that is worth that engineers must be on call, is a differnt question. I never had a job like this and I know I would never accept it as default for myself.
sometimes i remember some important message i need to send colleagues or clients... for that i like the telegram feature where i can send a message with a delay. i can write it now and it will be sent the next morning or whenever i think is a good time. i wish my email client had that feature too.
They can use a different platform, print the pictures on paper, there are a million ways to deal with these kind of issues.
An earthquake could strike and the event might need to be postponed.
If nobody's life or health is at risk, it is not urgent enough to sacrifice someone else's health for it.
I agree. But I think being on call is possible in a healthy way, if there are long enough brakes in between. Occasionally being a night on call is possible. (Well and normal if you have small kids, but having small kids and having to worry about getting an emergency call any minute, that would be draining)
not if they already committed to this one. you can't make such a change in a few minutes. limitations are so unusual that nobody would expect them and be prepared. and even if they were known ahead of time, you are also not expecting the kind of situation where you have to upload pictures in the middle of the night.
This isn't a 911 dispatching system.
