Hi I need some advice and hope someone can help me. I have been with my company 4 years. I have a 12 week notice period. But I believe that they have breached my contract. We had a new manager come in and it was Okish up until I was off sick early Jan 2018 for a week. This was my 5th time being off in a 12 month period. In my employee handbook it states that my manager has to fill in a absence review form after 3 absences in a year. (I am still waiting for the form to be done and forwarded to me). It also stats that if they are not paying me for sickness then they have to inform me prior to revoking sick pay, which wasn't done. I would like to know is the employee handbook part of my contract. The employee handbook is online in a portal. Because of the above and other issues with my line manager I decided to hand my notice in and asked for 4 weeks. My manager has refused this saying that your contract is 12 weeks but might be able to leave quicker. Then he has put an email out to all the other staff saying I will be here for 12 weeks!! The other issues include not given me the opportunity to do some of my role when I have a chance, treating me different to the other staff, calling me names and undermining me to my staff. The Bonus system that is in place has been a farce and a lot of the staff are owed money from this I have been told to put overtime through to cover this (been told that we have to be creative with the money owed!!) He tires to be a bully and the emails/phone calls I get can be quite harsh at times. I do not know where I stand on the contract whether they have breached it or not. I was going to start a grievance process but I saw another member of staff go do this road and they treated him like crap and he got sacked before it was investigated. I feel like just quitting and giving them all their gear back when the four weeks are up. I also do not know if I have a case for constructive dismissal. I have worked all my life and never had to do anything like this before. Please help.... Many Thanks in advance.
