Greetings for the day! To whom it may concern, My Boss keep on telling me, Give me your Emirates ID and I will cancel your visa and send you to Philippines and 1 year you can’t come here. I admit past few months I have absences due to my monthly period, so there’s months that I have 2 days absent but he never bother to say anything, so that’s why whenever I’m having stomach cramps and severe headache and back pain I’m staying at home, the major reason I can’t go to work when I have this it’s because I have to sit 12 hrs straight in office. I never complain when they cut my salary as I really need to rest those days. But I have never imagine that he will force me to send a resignation letter, that 2nd day I didn’t come to office he called me and was shouting at me. He constantly telling me, Send ur resignation letter right now, he called me 2-3 times and asking me to send through email with my signature but I can’t go down since I’m not really feeling well, I send my resignation letter without signature though, then the next day when I came to work he said he will accept/acknowledge my email. But he didn’t any way. So I thought the issue is finished since my colleagues was saying if boss didn’t reply, so leave it, just keep on working. But after that whenever he’s free he is telling me I will cancel your visa and send you to Philippines I will not allow you to work here in Dubai, it’s not my headache if there’s virus there or don’t have work there. I’m really devastated since I’m working with them for 1 year & 7 months, doing all the work that they’re giving me, they hire me as a Receptionist telling me that u don’t have much work to do here that’s why we offered you 2,000/-AED salary Only + accommodation & transportation, then I signed the contract which is written 2,200 plus transportation and accommodation, till this date I don’t have medical insurance that’s why whenever I’m not feeling well I just rest at home and take medicine I couldn’t go to clinic to get medical certificate since I don’t have medical insurance. Furthermore, the day I joined the company I started doing Data entry, Document controller, Admin Officer and Receptionist Job, despite the 12 hours duty I continued working with them since my Boss told me he will increase my salary if my performance is good, but after doing all my duties and responsibilities that they gave me, I even surpassed their expectations yet he never give the increment that he promised. And I never bother them for the increment any way, So now, I really need your help in this trying times, there’s COVID-19 Due to this pandemic It’s so hard to find a Job, most companies are firing staff, if my Boss keeps on telling me that he will cancel my visa, I’m fine with that even it’s hard for me, but what’s bothering me is that, whenever his saying that he will send me to Philippines and I couldn’t come here since he he’s planning to put ban on my passport. Before I joined this company I was working as Assistant Teacher/Sports Teacher in Government School. I’m a professional licensed teacher in Philippines with Certificate of Shari’ah Training Seminar which allow me to take the Special Shari’ah Bar Examination in Philippines and pursuing my Masters Degree. All these qualifications don’t matter this days due to this pandemic that’s why I’m so helpless and restless... Please advise me what I have to do. I badly need your help. Jazakumullahu Khayran.
