بالحكومة
"بالحكومة" means "in the government" or "with the government."
The word 'بالحكومة' in this sentence refers to the organization or body of the government where the subject's brother is employed.
يعمل أخي موظفًا بالحكومة منذ خمس سنوات.
My brother has been working as a government employee for five years.
Here, 'الحكومة' denotes the governing body or authority taking action or making decisions, while 'ب' is not used as the word is the subject.
قررت الحكومة البدء بمبادرة جديدة لتحسين الخدمات.
The government decided to start a new initiative to improve services.
In this sentence, 'الحكومة' again refers to the governing entity, and the word 'مع' (with) indicates direct association or collaboration with the government.
