Worst time of my life - Recruitment Consultant Navartis Employee Review

When I left, there was a significant outstanding bonus due to be paid to me, despite promises, I only received roughly 15% of it, a month late after chasing and when I questioned them, they ignored me completely and haven't contacted me since. Also, they have been funny with paying bonus late with other employees who worked with me at the time. I was paid less than all employees when I joined regardless of experience, but I was the youngest and a 'pay rise' happened which just moved me from minimum wage to the new minimum wage, while actively advertising trainee roles (below my role) for more basic salary than I was on. They use the word 'Fast-Track' which is a good scheme, however when you meet the targets they set for you, all of sudden they say they were not agreed and they get moved up so you don't get the increase in salary. There is also extreme pressure with targets from a very early stage and it only get worse the more you work there. I was also told new trainees were being told I had no qualifications, which could of been in a jokey way, however It's an absolute complete lie and I did not appreciate it. Total lack of credit for what you do, Lack of appreciation, severe favouritism towards certain employees. Expect contact out of hours, I was repeatedly rang at 6am for a week whilst my boss was away and also on most Sundays. Worst work-life balance I've ever had. Do not trust anyone.
