I just don't see what the big deal is. This job is easy and totally stress free as long as we do it correctly. Report any foreseeable issues like potential service failures to management. Have a witness each time. Don't speed or take any other shortcuts trying to make things happen that otherwise wouldn't be possible.
If given a difficult or impossible tasks just do the job like we all know it should be done and the consequences will fall in the lapse of the supervisors who you warned about those service failures. When they come after you for not "performing" just play it cool and remind them that they were given notice about possible service failures, or that you had too much work, and if they keep pursuing the matter file on it. There is no need to argue and get hostile. Just play it cool and keep doing what we are supposed to do.
