i've been working corrections "contract work" for the past year. compared to hospital nursing, the pay is significantly lower. due to the contract nature, there are no benefits and people at our facility seem to have to work for ever before a full time ie. benefits position is offered. i have intensive care back ground as well as many years of community nursing, but was placed at the bottom of the grid, regardless.
the nursing is varied from the ordinary passing of meds for a variety of ailments as well as organizing the inmates for sick parade (doctor's visits), to assessing inmates after altercations. it's seldom dull as you never know what type of malady you'll be dealing with. we do our own blood draws and ecg's routine immunizations and a good deal of health teaching.
to work in this type of position, you must maintain a very healthy respect for the fact that these people are generally there because they have crossed that legal line and generally must pay the consequence ie. imprisonment! i've generally found that if you treat these people as individuals, you don't have a problem. i have only had to lower my voice an octave, and am instantly supported by officers who are watching constantly.
hope this helps from the canadian perspective
