Understanding your concerns, it's clear that you're at a crossroads in your career. At 40, considering a career change can be daunting, especially with the current job market and the specific dynamics of your company. Here's a breakdown of the situation and some advice:

1. Evaluating the Current Job: The combination of a small company, additional outsourced work, and a sense of unfair treatment can lead to job dissatisfaction. It's essential to assess whether this situation is affecting your work performance and personal well-being.

2. Future Prospects: Given that the company's future seems uncertain and you're approaching retirement age, it might be prudent to consider your options. If the company culture and the potential for growth are limited, it may not be the most secure path for you.

3. Age as a Factor: Age should not be a barrier to seeking new opportunities. Experience is a valuable asset, and many companies appreciate the expertise that comes with it. However, it's true that permanent positions and salary prospects may vary.

4. The Case for Change: If you are unhappy with your current job and see little chance for improvement, a change might be beneficial. Here are some points to consider:

• New Opportunities: Research the job market to find where your skills and experience are in demand.
• Networking: Utilize your connections to explore job opportunities that might not be advertised.
• Professional Development: Consider if additional training or qualifications could enhance your employability.
• Financial Planning: Evaluate your financial situation to determine how a potential salary decrease might affect you.

1. Transitioning Strategies: If you decide to change jobs, you might want to consider a gradual transition, such as starting part-time or freelance work in your desired field before fully committing.

In conclusion, only you can decide if a career change is the right move. It's important to weigh the pros and cons, considering your personal circumstances, financial stability, and long-term goals. Seeking career counseling or advice from a professional could provide further clarity on the best path forward.
