I am at an IT job that I was very fortunate to get, but hasn't been the best fit for me. However since this is a local government agency, people don't get terminated easily.
When I was in my first trimester I was always dog-tired coming into work but my supervisor and co-workers were understanding of this.
Now in my second trimester I am getting my energy back but I am dealing with lot of stress because I suddenly became a single mom (I'm expecting in Oct 2014), so my work quality had taken a hit.
I want to get my focus back because that's what I'm being paid for.
My question is, how and when do I approach my supervisor or HR about my desire to telecommute after my 12 weeks maternity leave is exhausted. I want to be there for my child during feedings AND I also want to deliver excellent work to my organization.
Where I work, they give tasks, but they don't give deadlines. So how do I prove that I am an employee worthy enough to be trusted to telecommute (and go above and beyond expectations)?
EDIT:
I'm a full-time unioned employee .... I haven't spoken to HR yet .... will address more of these helpful comments and answers later
EDIT:
All your answers are great. The answer that says to emphasize this is temporary arrangement really hit a chord. And also, going back to office once or twice a week, and having someone bring the baby to office during feeding times (my office won't mind this one bit, there is even a small room in the ladies room for this type of thing).
Today I started being proactive and forced myself to focus on my tasks (still dealing with other emotional things right now, but that shall pass)
Your answers gave me a lot to think about .....
