Hey everyone. I'm Maltese, and work for a smallish Maltese company. I've been with the company for a bit over a year. It's always been the same bs that I have an attitude problem for not smiling at everyone that walks by. I used to work rather secluded so this issue was easily mitigated. Since moving offices, I have been placed in the centre of foot traffic. I no longer have anywhere to go for my break other than the break room(I used to go to a secluded meeting room or even leave the office and sit on a bench)...which forces me to be around colleagues even more. Today I got an informal warning that if my 'behaviour' doesn't improve, they'll have to take action. I don't speak to anyone outside of my team, I'm not rude to anyone but I don't let people walk all over me so apparently people are scared to speak to me. I just want to go into work, do my job, and leave.
Is there any way this can be argued as unfair dismissal if they do end up firing me?
