It is legal for an employer to refuse you to have a second job but to give you not more than 23-25 hours a week ?
As long as you can work the hours he gives you, providing any second job is legal, he has nothing to say about it.
Your employer can't legally bar you from having a 2nd job.
its none of there business what u do off of their clock call the BBB on them or workforce and labor
Seems to be the trend to limit hours. However, how you spend your off hours is not the employer's business.
