My employer has sceded me for two twelve hour days next week where I will be interfacing with customers at a conference. These are normally exhausting, I will be 28 weeks next week and I'm very intimidated. When not standing it will be walking and due to the nature of the work there are no breaks, no sitting. Snacking and drinks are frowned upon in front of the customers, and the one meal is at the employers whim and the employer is horrible... Really horrible! I am debating on calling my doctor to get a note. I could keep up before this. But the last one exhausted me and made me feel like I was going to pass out and that was a month ago.
