As an HR expert, I would suggest considering a few factors before making your decision. Firstly, it's important to assess your long-term career goals and aspirations. If working in a higher grade and receiving overtime pay aligns with your career objectives, taking up the position in the statutory body might be a good choice. Secondly, evaluate the stability and job security offered by your current permanent government position versus the contracted role in the statutory body. Government jobs often provide more stability and benefits such as pensions, whereas contract positions may not offer such security. Furthermore, consider the potential opportunities for growth and skill development in each role. A higher grade job in the statutory body may provide more room for advancement and learning opportunities. Lastly, assess the overall work environment and culture of the statutory body. Find out more about the organization's values, work-life balance, and the team dynamics. Ensure that the work environment aligns with your preferences and values. Ultimately, the decision to accept the position in the statutory body should be based on a comprehensive evaluation of these factors. It's advisable to weigh both the short-term benefits, such as higher grade and overtime pay, as well as the long-term implications, such as job security and growth prospects. Remember to also follow any contractual obligations or restrictions in your current employment agreement. Consult with your superiors, mentors, or trusted colleagues to gain further insights and perspectives before making a final decision.
