Assalamualaikum dear Brother,
without knowing the hole situation and the atmosphere at your workplace, I want to contribute my thoughts on this issue. My experience is: there is or should be always an option to keep your job and still pray your salah at time. Sometimes it will result in a compromise. Let's be serious you can pray the fard of maghreb in 5 to 7 minutes, if you recite short surahs. When you take wudoo before your meeting, you will be out for maximum 10 minutes.
It always depends on the workplace. I think your meetings are in an office place. This is actually more difficult, instead of leaving a warehouse. And is has to do how we Muslims represent our religous, when we have a good akhlaq and tolerate other people and their religion, often you don't get problems, so they tolerate you either.
Just be honest and polite as we Muslims are supposed to. And talk! Talk in manner, that's not overbearing, but make clear, you want a solution. A solution that's good for the company, but make clear, you are just away for 10 minutes and then back to work more productively. Make a compromise: Say, you stay 10 minutes longer. A lot of people are smokers, I guess you have even colleagues they need or want to take a smoke break. Try to pray maghreb in this time span.
