Can we decrease any employee's salary within a year without changing the designation?

Hi, Can we decrease any employee's salary within year without changing the designation?
Please someone suggest me the way we need to reduce their salary because of my calculation mistake.

Dear Noor,
Arithmetic error in calculation of salary can be corrected at any time and the amount already paid can be recovered as over-payment.

Thank you so much for sharing the valuable information with me sir but how we can correct PF amount which we already paid to PF Department, as I aware PF amount can not be decrease as per the compliance please correct me if I am wrong.

The exercise now you undertake is not reduction of salary but only the correction of the inadvertent arithmetic error in the calculation. The amount of contribution paid to the EPF so far is only based on the wrong calculation. When you set it right now, automatically the contributions subsequent to the correction will be less. Better, you inform the employee and the EPFO in advance.

Respected sir, without going through the contents of appointment letter and your goodself has agreed on calculation error , first see the how it happen, how is written in appointment letter and then decide, whether it is right or wrong. Truly your shashi pandey

Dear Shashi,
Your contention is quite correct and appreciable as well. But, normally, here at citeHR, the answers we give are strictly based on the inputs provided in the query only. Since the poster has categorically mentioned that it was only his wrong calculation that warrants the remedial measure, I think it would not be nice to probe further how the calculation could be wrong. If the situation is otherwise as you've doubted, my answer would be of no use to him.

Dear Noor Alam,
Can we decrease any employee's salary?
Answer is " No"
But you can, provided if the employee is paid more than the actual salary promised in appointment, is due to wrong calculation or clerical mistake. That is not called as decrease of salary rather recovery of over paid amount.
