Write an email to Tina asking what tasks she wanted me to complete today. See if she got my report from yesterday and if she's had a chance to review it. Keep it short and sweet. Sign it, Amanda
Good morning Tina,

I am writing to inquire about any tasks that you'd like me to complete today. Is there anything, in particular, you'd like me to tackle?

I was also wondering if you had an opportunity to check over my report from yesterday. Your input would be most appreciated as I value your feedback. 

Thank you for your time,
Amanda
