Ok say you work at a prison, where there is high turnover of correctional officers and not an adequate supply of them on shift at any given moment. When you were hired in this support staff position (for example office clerk or secretary), your job description was pretty clearly defined--to clerical and/or secretarial duties. You liked the salary, you were fully aware of the job description, as explained to you, so you accept the position.
During the early part of your employment, those in charge are replaced by new people and suddenly things change. You, who is not a certified officer, who was hired as a secretary or clerk, who has absolutely no training in the area of handling inmates on a physical level, is suddenly expected to stay late to serve meals to inmates, shake down their cells and worse--physically pat them down for contraband.
What would you say to those in charge if you were told to do this.
If "go to hell" was part of your answer, then "DING DING" we have a winner.
