I have pretty good attendance at work which I am glad. I don't call in unless its an emergency.
I have noticed staff call in sick due to personal reasons, or say they shovelled the snow and now their back hurts. They call in sick from work, and then we work short if there are no replacements.
Thing is some staff say they just don't feel like coming to work, but they don't feel bad. Some say they are stressed which I understand, family complaints, managers on your tail etc... sometimes you are not sick and just need a day of healing mentally. Some staff do get burnt out. Some staff lets say had an argument one day and did not get over it so they need one day (sick) to recover but not actually sick.
But, do you feel bad if they work short? Myself in my experience when nurses book off and I am alone on the floor, I am fine you are not hurting me, you are hurting the Residents. Even when PSW's book off as well.
Have you ever called in when not really sick? I notice that its a habit for some staff.
