1. A worker who is familiar with his employer and knows that he usually only has funds on certain days, such as on market day, does not expect to be paid on the day he worked. Therefore, even if by chance the employer does have the money, he will not transgress the prohibition if he does not pay on that day. This is because the worker, in effect, hired himself on condition that he will not be paid that day. Nevertheless, on market day, or whatever date the employer does [usually] have the funds, the employer will transgress the Rabbinic prohibition of, Do not tell your neighbor, “Leave and come back; tomorrow I will give it,” when it is already by you(Mishlei 3:28).

The same rule applies to those who customarily pay their workers only after tallying their hours. In this case, as well, they only transgress the prohibition [of bal talin] after calculating their due, since to begin with they were hired on this condition.
