My attitude is very close to that of Chevygirl's. I enjoy being an admin because of the variety of work and added responsibilities given to me by my boss, who has learned to delegate more and more. However, I am tired of having to leave these assignments and be forced to cover the front desk on a once-weekly basis, and for emergencies. It's not something each of the admins where I work has time to do anymore, and we can't convince management to handle it in any other way. I used to think this was the most aggravating thing about the job, but now...
My boss has had to turn over from our headquarters facility the duty of data entry on the SAP system. I am finding this extremely tedious and it makes me want to scream when HQ refuses to give me the instructions I need to get the job done. They think I should be able to figure the system out on my own. It rarely works the way it should, and even when it does, it's extremely cumbersome.
But on the whole, I like being in this type of job. I like to help people keep their meetings and trips organized, make suggestions for presentation improvements, taking notes at meetings and following up on them. I enjoy the added responsibilities of monitoring certain systems. The varied duties are much more appealing than being stuck doing one thing all day long. I have experience doing transcription work, supervisory work, and tediously strict data entry. I've got to say that admin work beats them all, which is why I returned to this type of job after a break of many years--some of it as a SAHM.
