Now my dear friend please try to understand just as a patient is important to a doctor , saving lives is important to a firefighter a CEO or BOSS is important to a Office Going person as he is the one who is to answer if work is not done in time.
So your mentioning in first post " even if he is busy with CEO in meeting" is totally baseless, when you agree to doctors emergencies then you should also accept that for your company during important meetings, or interviews or discussions which happen during the day and if they fall during namaz time or friday they are important than prayer and require your time.
Until you realize this and change your mindset it wont do you any good. Because in all these things only you need to suffer. I lived all my childhood in mughal dominated city wont divulge the name and have had close muslim friends, and it totally depends on their brought up, one friend doesnt live to eat non veg, another muslims used to make fun of him, another one was just like you, he used to go to a room upstairs 5 times a day for namaz, and the beauty of this is his supervisor who was a muslim himself had fired this guy because everytime he used to meet this supervisor, he used to greet in urdu salam wallekum, so in a day time you meet your supervisors numerous time in a day and every time he used to greet in urdu and while leaving also he used to greet, that supervisor who inspite of being muslim clearly explained to subordinate that religion and work is different once you wished me good morning in urdu in morning thats enough here we come to work.
Because of this one person leaving work place during office time 4-5 times in a day other staff i.e hindu + muslim staff together, felt that why he is doing like that as to them or to office as per rule you are only allowed lunch break for half hr and this person used to take 15 mins off for 4-5 times a day whereas other muslims of his age i.e 22-25 yrs old did not go with him for namaz, He also did not join us in lunch time wherein we used to have lunch all together and only he used to go upstairs and do namaz and eat alone. From your post i can only remember that persons name in my thoughts.
Also coming to other points, let me tell you even hinduism prohibits all these things but i wholely agree that many times i have done all of the below mentioned points at some or other point in work / life. Many many many times no record of that, but what to do you just dont have a choice, also i dont regret doing these things because all done on behalf of others i.e pressure given by others. These things happen in life and i dont care about them as long as the bad things are not originated in my mind and are done due to pressure given by others. Why we do these to earn money and keep our job stable, so if we have own business then we need not do these things at all......
5. A Muslim can never lie or cheat with anyone (i.e., A Muslim can't lie or cheat with other employees on the behalf of his boss.)
6. A Muslim can't forge HR annual statements or do any manipulation in HR audit - on behalf of his boss
7. A Muslim can't do any favoritism or nepotism on behalf of his boss
8. A Muslim must ensure equity and justice at all times and with all people
9. A Muslim can't pay or accept bribes
So friend, it is your life but truth is you cannot just do these things in office tomorrow if it is objected you may feel hurt, best thing you can do is instead of being employed you can be employer start your own business be your boss work at your own timings follow your own policies, because it is not a question of HR job or Accounts or Engineering job, even a hotel receiptionist needs to tell lies or forge data or tell rooms are full when they really arent, so best option is if these things hurt your conscience too much, you start own business and be your boss.
