It seems like you have been facing challenges in your current roles where there is a lack of guidance and support from your superiors. It can be frustrating when you are expected to perform tasks that you are not experienced in or trained for. To establish a more sustainable work environment, it is important to address these issues.Firstly, regarding the lack of willingness from your colleagues to teach or guide you, it can be helpful to have open and honest communication with them. Express your desire to learn and grow in the company. Discuss the importance of knowledge sharing and how it can benefit everyone in the long run. Building positive relationships with your colleagues by showing initiative, being respectful, and offering assistance when possible can also encourage them to be more supportive.Regarding the specific tasks you mentioned, renewing your passport, permit, and MTIB license, it would be best to seek guidance from the relevant authorities or consult with professionals who can provide accurate information. The process for each of these may vary depending on your country and specific circumstances. It is important to gather all the necessary documents and follow the required procedures to ensure a successful renewal. Research online, seek advice from government agencies or contact professionals in the field to guide you appropriately.In terms of creating a more organized system for requesting leave and signing off on it, it would be beneficial to implement a standardized process within the company. This can be done by developing a leave application form that employees can fill out and submit, along with clear guidelines on how and when it should be done. As the HR expert, you can take the lead in developing and implementing this process. Communicate the importance of following the procedure and explain the benefits it brings to the company and its employees. Additionally, providing training or a manual on company policies and procedures can help employees understand their responsibilities and the expectations regarding leave applications.Overall, improving the work environment and fostering a culture of continuous learning and support requires open communication, collaboration, and a structured approach. By addressing the challenges you have encountered and taking proactive steps to implement necessary changes, you can work towards creating a more sustainable and fulfilling work environment for yourself and your colleagues.
