puddicat,
I can safely assume that you do work in the Care Sector.
I don't like to generalise normally, but certain aspects or workplaces that we work in can get to this situation.
Just stay calm tomorrow and as you have said, You have written some things down to bring to the attention to your Line Manager.
I would not be discussing this with anyone and just tell your colleagues it is not allowed to be discussed, whatever the outcome may be.
I can relate to what you are saying, a few may spout at team meetings and them others sit and say nothing until they leave the room, then they start. Do not be fighting anyone's battles for them. let them all complain if they have a grievance. Just put across your point, and a valid one you have too.
You obviously care very much for your Residents and I am sure your Manager is aware of the good workers and not so good workers.
I always say, if someone thinks by going off work for one reason or another, it is not their Employers it affects, it affects their colleagues workload and also the Residents.
Tell your manager that you put your Residents first, unless a ral crisis comes up then you would be as understanding as anyone else.
Got to say, I would get fed up also of having scans pushed in front of my nose every minute of the day. Tell your manager the day you stop caring about your Residents is the day you would look for alternative employment. Make sure you are calm and collected, with abit of humour thrown in. x
