My new employer made it very clear on my 2nd day of work that they can "see" everything I do on my computers. I work at various locations, so about 5 computers all together.
Every computer for the organization is tied to the main server, and everything I do can be "seen" in the form of log reports and server sharing. Also, they can check the site phone logs in real time and see outgoing calls made. Don't know about the cell phones yet. :)
But, they are upfront about it.
Basically, when we are at work we are there to do a job that we get paid for. That means our employer expects us to use our time wisely, and not perform personal business while they are paying us. That is what break and lunch time are for. Yes, everyone, takes a personal phone call or two, and occasionally checks personal email. But, do so knowing that your employer has a right to look at whatever is stored on their computer....because it is their computer.
It is very easy for them to set up programs that monitor your usage. I liken it to the parental control function that I have on my Windows Vista - it gives me a report of every time my son logged on, every web site he visited, and every program used.
I don't mind really, they pay me to do a job, and I don't do anything that they can't see.
Good Luck
God Bless
