Being a BPO company, of course, taking a leave of vacation requires approval from not only my supervisor but also their boss. We'd need to file the leaves in advance, and your performance for the current and previous months can affect the result of the approval very much. Also, it can get really tiring to speak since I handled a voice account, with non-stop calls. Dealing with irate customers also took a toll on my health mentally, which caused me to take a break.
