I have a particular case where the central government agency is employing security guards from a private agency and wants to calculate their wages on a daily basis, i.e., according to the number of days worked. If the security guard has worked 31 days in the month of January, then they should receive 31 days' salary, and if they have worked 28 days in February, then they should receive 28 days' salary. The agency insists that the salary should be calculated on a daily basis rather than a monthly one. Can you please assist me with this matter and provide guidance on any applicable government regulations?
