I work for county government. I've been in county government now for 23 years.
I was a baby when I started. Anywho. I had worked in another county for 19 years and then we moved because of my hubbys job. I applied at the same office up here just different county and they hired me the same day. So here goes.
I have been offered a job same county just a different office as 1st deputy.
They make more money )lots(more. I am going to take the job come the first of the year. No one but the new office holder and I know this. My friends in the office do not know. I am afraid they will be really mad and upset with me for taking this new job because i will be making considerably more money than them and they have been there longer than I have. They are my friends and have helped me though alot. They even drove 150 miles to be with me when my mom died. I don't want to lose their friendship. But I also have 2 kids in college and a new grandbaby on the way. Thanks for reading and any advice you could give.
