Very Worst Company - Senior Quality Engineer BGR Energy Systems Employee Review

Due to my situations, I joined in BGR with very low pay scale, Eventhough I have 6 years of experience. However I feel better at that time. Where ever I joined, I got the good name on my work from management. The same had been carried in BGR also. I put my full effort for four years. But the management didn't provide even a single increments for four years. My head also suggested and provide the NOTE FOR APPROVAL for salary revision . Management didn't bother about it. Who were join after April 2016 they didn't get any increments till date.
