I understand that this might be your first job, so as someone with experience, let me offer a few suggestions from my perspective that may help you understand your current situation better. It's important for you to reflect on your job circumstances and make decisions that align with your best interests.
Feeling guilty about being let go without a clear reason is not uncommon in today's job market. There are plenty of opportunities out there that you can explore. However, from my point of view, the reason your employer asked you to leave might be more complex. An employer who shows compassion towards a sick employee is unlikely to dismiss another employee without a significant cause for dissatisfaction. There may have been other incidents during the six months leading up to your departure that contributed to this decision. It's essential for you to reflect on your performance and identify any areas where you may have fallen short. While you don't necessarily need to apologize to your employer right away, self-evaluation can help you prepare to address any concerns that may arise and improve your performance in your current and future roles.
Suggestions for Moving Forward
I recommend creating a list of your achievements and contributions to the company, no matter how small, to showcase your value to your employer. When discussing the situation with your boss, start by acknowledging their positive contributions to the team, as this can help set a positive tone for the conversation. It's also important to express your willingness to understand the reasons behind the decision, while also emphasizing your commitment to self-improvement.
If you are willing to give it another chance at your current workplace, go for it. Otherwise, consider this as an opportunity for growth and be open to new and potentially better opportunities that may come your way. In either case, stay positive and optimistic about the future.
Best of luck!
