I've currently been signed off for three weeks due to pregnancy problems & stress. The doctor has advised I take the time off as I'm becoming anxious & depressed. However, my boss is threatening to have me sacked due to poor attendance yet I've only been off due to pregnancy related issues. If he decides to sack me do I have any rights? I feel like I'm trying to destress and relax whilst having time away from work but his response and lack of support is making me worry. Additionally, at work he seems to make me feel I'm not great at my job and belittle me in front of others. Is there anything I can do? Am I wrong for having the time off?
