PharmaT, in my opinion 'proper' people would say you do have a right to feel tired and that it is totally normal that in your circumstances you would feel exhausted as you do.
I am totally with you on this. I think this is a massive problem that little attention gets paid to.
We don't get breaks at all. Officially on paper we do 'when we can' but in reality we never can. I know this sounds highly far fetched but it is true. If I didn't do what I do I think I might have a hard time believing it myself. Occasionally, there might be time for one person to have a break, but no one wants to be that one person going off for a break when you know that others will not get one. Occasionally, a foolhardy person raises this issue. Big no no, this never goes down well, only troublemakers would winge about not having a break.
I think having a break to the assigned minute should be mandatory. I do think if the 'powers that be' set it in stone and made it mandatory a way would be found. To me it is too lame that there is not enough time. A way should be found to make the time, for goodness sake!
If this was sorted out, I think morale would literally soar, turnover and sickness rates would be less, employees would be healthier and happier and do a better job and those being looked after would benefit.
This is a real bugbear with me as you can tell. It does feel like crying out in the wilderness and that it feels like a waste of breath. Who listens, who cares if we work exhausted and eventually become burnt out? Perhaps one day, when I retire and am safe from possible risk of being labelled as a troublemaker, I may well campaign about this issue.
Just want to say I understand Pharma. Try to make time to rest to when you are at home. If it means letting standards slip a little, let things go, is my advice. You are more important, put yourself first rather than the jobs.
