As an HR, we recruted one Business Development Manager and given appointment letter stating that she is responsible in a particular region/states to develop and increase business. Even after paying their salary for a few months, there is not a single business generated and the company spends thousands on her travel to several states. Even though she committed in writing that she will do this much lakh of business in one month, nothing happened and in next month, we sent a notice mail stating that during your tenure no sales happened and that next month's salary will be based on any sales from her. Since in 3 months not a single business developed and we spend lakhs towards salary and travel, is it okay to hold the salary? We have not given a termination letter to her so far and she demands a salary for the month in which she did nothing. This job is WFH and not from the office.
