The work load for one person was very hard.
You should be able to voice your concerns about your work load.
Most of the managers are great people others are selfish and non concerning toward their employees. They are only about brownie points and not the person doing the work.
The job in the various buildings was not bad and most everyone is great.
The hardest part of the job is being overworked and nothing is being done about it. They expect you to do all and then demand more.
The most enjoyable part of this was the people you are around and your coworkers.
