I’m not on call
When i applied for this job I was told I’d go on the on call rota which I didn’t mind, especially with the extra dosh plus learning the environment.
After joining I was told I didn’t need be on the rota and therefore no extra dosh.
I was fine with that.
So I don’t have work mail or chat on my personal phone. Outside of working hours I will answer the phone if they call but I limit who has my number and do let whomever calls know I’m 9to5 only.
Even when it’s hectic at work, once my hours are done that’s it, switch off and do something less boring instead.
If they want me to do more hours then we can talk overtime first.
I know it sounds belligerent but for decades I worked more hours than I should and watched those around me get applauded for my graft. The trick is to shine when it matters.
