there are no more IT emergencies for the next week so that it can get done properly.
Then make sure that the space is available, even when new and unexpected items arrive.
And make sure that we have time to go over inventory (no HDD failures this week).
And make sure that ALL end users know that the IT department is doing other tasks and do not have time to deal with problems, and leave a message telling them to reboot and everything will be OK for another week.

It all depends on your role, space, and how busy you are. It is not just being lazy, so I have to disagree completely. When I am not busy, I often tidy up once a week. When I am busy, I am staying late without pay, crunching to make sure that a high level attorney is still up and running for the weekend, and if the legal svr team needs help, aiding them.
just stating that if it is not always clean is being ignorant of a technicians job duties. It makes assumptions that we are all too lazy to get things done, but if management would staff better, this should not be an issue at all.
