I guess people have different priorites concerning attendance. I think most feel that if it is possible to get to work, they will try to. I think most of us at one time or another have been sick, had the flu, colds, aches and pains, severe lack of interest, or what ever the reason might have been.
But we still manage to get to work and try to do our best even when our best isn't 100%. I think there is that driving force within us that makes most of us try to give the effort. I also know there are times when getting to work just isn't possible.
I also think there are people that don't have the maturity to have their priorities in the right place yet. Those are the ones that could care less if they had a job or not, they just seem to do things that are convenient at the moment. Not giving any thought to who might be affected by their actions. Those are usually the same ones that cry the loudest when things don't go their way.
I know there are times when a person just can't get to work, whether on time or at all for whatever reason. If there is a pattern formed where a person misses work continually, then I think there needs to be some thought given if that person really has what it takes and has the maturity to be a team player at the work place.
