the case supporting these assignments is that they give you experience for working in groups and as a team in the business world. but, even on the apprentice, trump has problems with these geniuses. the difference in the business world is that, hopefully, you have a supportive boss who is fair and uses their authority appropriately to start a fire under these kind of people or get rid of them.
what i always did is made sure that i was in one of the controlling positions in these projects. when i and others who were willing to get the work done saw that a few weren't getting involved i (we) felt there was no choice but to pick up their slack and do their part of the project. any work they are going to contribute is going to be at the last minute and be mediocre at best and i was never willing to let my grade suffer because of them. i also made sure that the instructor knew early on what was going on. i worked with one group where several of the group members actually turned their back on one of these slackers and told her to bugger off when she finally decided at the last minute to get involved after failing to show up for strategy sessions. she ran screaming to the instructor who told her (ha! ha!) that she just had to work it out with the members of the group. the only problem with this is that you are stuck with the slackers often also getting the same grade for all your hard work. however, you really don't have much choice. you either take a lower grade as a result of the slackers not doing their part, or you get a better grade because you took over and did their work. in the incident i referred to, the other members of the group told this student to, basically, sit down and shut up during the oral presentation! she actually had the gall to be mad at them.
the thing is this. . .in the working nursing world, you can't sit back and ignore problems that come up, which is what slackers like this tend to do. these kind of people just don't make very good nurses and problem solvers because of their procrastination. so, in actuality, it is revealing a serious character flaw in them. hopefully, this will be noted by nursing instructors down the road and get added to the assessment files kept by the nursing departments on their nursing students for future job recommendations. on the bright side, and you have to think to the future to accept this one, think about the experience you are gaining in leadership, management and people skills. i know that sounds kind of lame, but the experience will help you to recognize this kind of person later in life and work situations. it also gives you some experience in learning to adapt, re-evaluate, re-assess and intervene to make changes in plans as they are needed.
i wouldn't continue to wait for these last 2 people to join in on the project. i would encourage everyone of the current group to split the work equally and just leave these other 2 goof offs out of loop. let the instructor know what has happened. realize that unless the instructor allows you to dump them from your group, you will have to share any grade you get with the 2 deadbeats because you really have no other choice. i would make sure that everyone else knows exactly what these 2 did (not) do for future knowledge. hopefully, you won't be seeing them in nursing classes.
