It's so easy now to send and receive salaries using bitcoin. No need to queue for long to withdraw money if you use bitcoin. That's where the convenience is. Another advantage of receiving a salary in bitcoin is that it can be saved for a long period of time with measurable financial management partly to be exchanged for fiat and partly for investment.
There is only one obstacle, not all countries accept salary payments in bitcoin which is legally permitted like accepting fiat currency.

Workers who live in underdeveloped countries who find it difficult to get internet will experience difficulties. But that is not possible because the company where I work is usually located in a city where internet access is available, so I will ignore the issue of difficulty in internet access.
If I experienced the same situation as you in paying salaries, it would be a pleasant thing.

Good job in convincing the employer.
