Hi Pushpa,
😃 You received many versions clarifying your doubt. Let me provide you with one final version. This is strictly from a management point of view.
Leave is a prerogative of the Management. Leave is considered 'granted' when you apply in writing to the Management, and the concerned authority communicates in writing that the leave you applied for is sanctioned. In all other situations, staying away from duty is termed as "absence." However, the categories of Casual leave and sick leave are not strictly implemented in this manner because absence in these cases is due to exigencies or illness. Generally, oral information is passed on to the employer, and it is "accepted" or presumed that your absence would be validly "regularized as leave" once you rejoin and submit your application for sanction. Hence, in such situations, each organization follows a different principle of either marking CL or SL or A for absent in the attendance register. However, from Management's point of view, until your application is clearly sanctioned, it is considered 'absence.'
Now, regarding LWP, as others explained, LWP can arise in three situations. Firstly, when your employer agrees to consider your absence as leave, but there is no eligible leave balance. Here, there is a technical constraint, and the leave is sanctioned as LWP and authorized. The second situation is when your employer is unwilling to sanction leave because you took sudden leave, and as a disciplinary action, decides to treat your absence as LWP. This is considered "Unauthorised absence" and is a negative record in your attendance/career. The third situation is when there is a family emergency, or you need to be away for important reasons for 2 or 3 months, either domestically or internationally. In such cases, you can 'apply' for LWP seeking special sanction. This is usually considered on a merit basis by Management and sanctioned according to their policy guidelines. Generally, each organization allows 12 to 18 months as LWP eligibility for extreme exigencies, to be sanctioned by the Board of Directors on a case-by-case basis.
Therefore, "Absence" is a term used "until" your application is sanctioned either as CL/SL/PL or authorized LWP leave or unauthorized LWP. Generally, where employees do not inform ahead, the employer simply marks "A" in the attendance.
I felt it necessary to inform you in this detailed manner because employees should not take the leave sanction procedure lightly. Providing prior information to the employer and promptly submitting a leave application upon rejoining should be taken 'very seriously,' otherwise, there may be negative record notations in your career profile regarding your laxity concerning leave rules.
😃😃 Hope this guidance is helpful to you.
