How to determince the number of workers to be assigned to jobs in queue

[elhananjair]

Hello friends,
I am new to the queue systems in general, recently I have been working on a simple project. I have two main jobs that get executed in the background, and I scheduled it to a different time that repeats itself daily at a specific time.

I created one queue like this and add job to it.

``
const queue = new Queue('bg_process');

await queue.add('first_job', { intv: 3 });
await queue.add('second_job', { intv: 4 });

And then I created a new worker and process the jobs here: 

const worker = new Worker('math', async (job) => {
if (job.name === 'first_job') {
console.log(job.data)
} else if (job.name === 'second.job') {
console.log(job.data)
}
});

So is this a good way to handle multiple jobs in one worker or should I create another worker and separate the jobs into different queues? 
As an additional thing, I am using Bullmq because the background process is somehow blocking the job, and it blocks the event loop and the front-end UI becomes unresponsive and that's why I am using it. I found it very useful and it worked fine before I changed my code to the above method, before this I just created separate queues and workers. 

Any support is appreciated. Thanks
