You may worry that they are looking for an excuse to say you can't handle your job. It's best to get these concerns out in the open. Assure your boss that you will be able to keep up with your job and brainstorm ways to accomplish this in different scenarios.
For instance, you can ask if working from home is an option.
You may be able to work shorter days and come in over the weekend to get caught up. A supportive boss will work with you during this time to help you manage work and your pregnancy. A boss that doesn't do this is one you may not want to work for in the long term.
After the Baby is Born
Laws are in place to protect your job and allow you time to recover after the birth of your baby. If you have been employed with your current employer for at least one year, you are entitled by federal law to up to 12 weeks of unpaid maternity leave.
What this law doesn't protect is people's perception that they can do without you or that you won't perform as well once you return.
Even though they are not allowed to fire you to prevent your return, you may worry that it won't be the same once you go back to your position. The best way to allay your fears is to talk to your boss and assure him or her that you can handle the responsibilities of the job and being a new mother.
Your career may have once been the most important thing in your life and now it must share that role with your baby.
However, it is possible to be a good mother and a good employee at the same time.
While the challenge isn't always easy, it is worth the effort as you set an example for your baby that will serve him or her in the future.
