Lord help this person with their work and not be nervous. Help them to remember everything we do we are to do it as if to You so the Glory be Yours. May they gain confidence in their job so they won't have to be nervous about their boss. If it is they finish their job have them remember there are always things to find to do at work, like follow up work, or offering to help others. That will impress the boss, and they may get a raise or a promotion.
May your perfect will be done in their life and their situation. In Jesus mighty name I pray amen.
