I have endured bullying and discrimination since a manager was appointed at work, without going into huge detail as this would be a very long post. They seem to be treating me unfavorably because I'm a woman and because I'm currently 5 months pregnant.
The straw that's broken the camels back is that I went for an internal position and they have given it to a less suitable candidate than me (they are less senior, they have less responsibilities, they don't work the hours specified in the job, they have less experience etc). This person is a man and I'm a pregnant woman, I can only assume I have been passed over because of the pregnancy. The company is only aware of the pregnancy because of unfavorable treatment this manager put me through previously. My union was involved with that and there is already a case open.
I have written a email that I can send to HR asking for a formal investigation and I'm aware that once this has started I can start a ACAS case with a view to take it to an employment tribunal should I get to this point within 3 months (the deadline although extends slightly once ACAS are involved).
I'm the first instance I will ask my Union what I should do. I guess my main reason for submitting the grievance is firstly because of the upset of being turned down for a job for a less qualified individual, but also because I don't know how much more of their poor treatment I can endure.
While formal grievances aren't supposed to go against an employee my concern is that they will protect this more important manager over me and with the pregnancy I need this job.
