Dear Lalitamore,
If you intend to initiate disciplinary action contemplating either a reduction in pay or termination, etc., you have to prepare a strong base by issuing a warning letter indicating all the occasions where the employee has absented without prior sanction of leave or proceeded with loss of pay but without proper intimation, etc. Also, indicate that due to habitual irregular attendance, the same will be viewed very seriously, and further repetition will entail severe punishment.
If there is no improvement in his attendance and the company thinks that allowing such irregular attendance is likely to cause damage to the company's business or give wrong signals to other employees who are regular in attendance, then final action can be taken by giving him a show cause notice indicating the contemplated/proposed punishment.
Hope this clarifies.
