I need some advice please, I work for a well known retailer and while I was pregnant I was treated quite badly. They took my role off me which I was fine with and put me on a more customer service based role which included working on the customer service desk. I was told several times that other staff members were complaining about me because they wanted to work on the desk. I was then put on a till sat down for 2 and 3 hours at a time, in their own risk assessment they said I couldn't sit down or stand up for longer than an hour at a time. They only carried out a risk assessment at the start and that is it, I was left upset frequently by a supervisor who was horrible to me. I complained more than once and was told by management that they would get someone to "look out" for me. Nothing however changed and due to bad health I was off sick towards the time leading up to my maternity leave. I had sent in all the relevant sick forms and one day a manager who had not been nice to me phoned me and said that I hadn't called them that week and repeatedly kept strongly implying I would be receiving a disciplinary when I return to work after my maternity leave. I was extremely stressed out and that same evening I went into labour nearly 4 weeks early.
During my maternity leave I was diagnosed with anxiety disorder and depression, I was not once contacted by anyone from work throughout until a week before I was due to go back. I sent a letter to head office informing them that I would not be returning. I then heard nothing back and then in the post on Saturday 2nd Feb receive a letter inviting to a disciplinary for being AWOL it was to be held on Friday 1st February! But It was postmarked on Feb 1st and so there was no way that I could attend. Please can you give me advice on what to do and how I go about it?
