    compensation offered is too low compared to the workload, responsibilities, and experience required
    The good thingsThe good thing mon - friday working days
    The challengesExperienced employees are being compensated almost the same as fresh graduates, which can feel undervalued considering the years of technical expertise and field experience involved. Management and salary structure should better reflect employee skills, contributions, and industry standards.
