I currently work as a 1099 sub contractor doing freelance bookkeeping. My boss does not want to give me an email account and asks me to email on her behalf. She gets on me for grammar, capitalization, etc. She states it needs to be professional. If someone gets back to me, she says I need to notify her of responses immediately. On some occasions, she asks me to draw up a draft and then she will go in make changes and send. She doesn't let me talk to people.
She is now questioning how long it is taking me to do my tasks.
This has been going on for 6 months now.
How can I politely ask for more empowerment (my own email account and an introduction to the company I am supporting)?
