A few things here:
I am okay and believe in the right for unions to organize. They should be free to hold campaign drives as long as it does not interfere with the things mentioned in the redraft. Employers cannot regulate employees to who they talk to off the clock and punish them for that as long as it is not causing a danger in the work place, nor should they be allowed to hire people to intimate employees. I agree there.
Second, union organizers should NOT have free access to businesses any time of the day to the point where they begin to interfere with day to day operations though. There needs to be restrictions because businesses are independent entities and not subject to the whims of unions who are, after all, businesses in their own right that look out for their own interests. We have to respect the boundaries of private enterprise along with allowing the employees to have choices on whether to unionize or remain unaffiliated. A monopoly on either is good for no one.
Third, it should be the unions' job to make themselves known to employees, not the employers having to advertise for the unions. That is not their job. Employees who wish to unionize may do so, but it is the union's responsibility to get their name out there and help the employees organize, which they are more than capable of doing and have done for years and years. It is not the job of the federal government to tell businesses that they must advertise for the unions or give employees handbooks/posters to tell them how to unionize. We are forcing them to favor the unions over themselves. Both sides have their interests - that's what is so interesting about "collective bargaining." It's a bargain! We must keep that balance.
