My coworker is a slacker. She spends most of her time on Facebook, personal calls and personal emails. I'm the only one who can see it because we share an office and our desks are situated so I can see her computer screen. I told her once she spends way too much time online and personal stuff and she when running to the office manager about me. I told the office manager why I said what I did and she agreed that my coworker did only clerk typist work that could be handled by a temp but that her boss had no problem with the way she worked and that I should just mind my own business and not say anything. I did a bad thing and peeked at her paycheck and saw she's paid more than me even though I've been there 7 years longer than her. I've been told I'm rated the #1 asst. out of 5, my reviews are "excellent" and yet, out of five assistants, I'm the second lowest paid. Two of the other assts. Have been there 10+ plus years longer than me. I come in early and work late every day. I don't run out of the office at 4:57 pm like the other assistants. I love my job and since I'm 62, getting another one would be very difficult but I feel like I'm not appreciated and want to leave. But I can't afford to. This has me very upset and I stew about it 24/7. What can I do?
