I've got senior title at engineering field at my current (startup) company, where I've worked for almost one and half year. And then I promised by managers that my salary will be increased after 3 months, because such kind of processes will start in 3 months. After 2 months my company's biggest client chose not to renew our contract and my company started experiencing financial difficulties though hiring and staff replacements are continuing. After 3 months passed I remind my managers about my promised salary and told them that if I would not get my promised salary I have to quit as I took out a loan based on my projected salary. I mentioned that it's really a critical requirement for me. They told me that will speak to CEO and will get back very soon. Now almost three weeks have passed without answer.
I'd like to ask, is it normal behaviour that they're remaining silent? Because in my opinion, even if they don't have a definitive answer they could keep me in the loop, right? Should I break the silence and ask for an update directly? I like my job and tasks I'm working on, so I'd rather stay on.
