Assuming that you have accounted for the work time required to deliver the jobs at both workplaces, what is motivating you to take up the second job? Have you considered the growth prospects? How far is it aligned with what you want to become in the next financial year?
Understanding Dual Employment
To begin with, every part-time job is not dual employment. From a talent's perspective, balancing career expectations from the job may not always happen from one job. For example, a faculty member who teaches at an MBA college may also run a management consultancy offering expert guidance on real-life industrial problems. This is not dual employment; it is actually an arrangement where one job supports the other. Working through real-life problems helps the faculty member remain relevant, whereas the research required to teach students makes them an unchallengeable consultant to the industry.
Defining Dual Employment
Dual employment, by definition, is offering the same skill sets one is hired for to more than one employer. It also has to do with the number of work hours spent. For instance, a salesperson cannot sell products for two different companies simultaneously – that's dual employment. However, an IT engineer teaching classical dance beyond work hours for profitable gain will not be dual employment, as the skills required for both workplaces are entirely different. A school teacher managing a private tutorial to teach students from the same school would be considered dual employment since they are offering the same sets of skills for which they are hired for profitable gains.
Analyzing Your Situation
In your situation, the first job requires an in-depth understanding of electronic machines and benchmarking them to quality standards. Do these machines have anything to do with health or medicines?
On the other hand, the medical billing process will require you to work on processing documents, identifying, indexing, tagging, online filing, or defining the documents. None of these skills require knowledge from your primary job.
Alternatively, the employer at the medical billing process should not be concerned about you using the knowledge of billing documentation at the factory.
Considerations for Dual Employment
However, working at two different establishments, both registered under the Shops and Establishment Act, is a point to ponder. Please disclose your intentions to both of your employers. Share why you need both jobs – whether for greater cash flow or career aspirations. Be clear about why it cannot be achieved from one workplace. Share a detailed plan on how you would manage your time and attention.
Has anyone from the factory ever managed a part-time job? Research how people with part-time jobs at the factory have convinced the employer. Prepare your data and work closely with your reporting managers at the factory on how effective you would continue to be even after working at the call center.
Speak openly about your monetary conditions if that is the reason for the second job. If your employer cannot meet your monetary needs, they might allow you to take on the role. A salary hike would be a percentage of your salary, not double the salary. Any amount of overtime at the factory might still not be enough. Present these points to them.
Career Development and Future Prospects
Take a big-picture look. Understand where you want to reach in your career and how. Ultimately, any job you do will make you better for your next role. Identify what competencies from each job will help you build it. Each role we take opens up potential we never knew we had.
Wishing you all the best!
